heading down the final stretch... my fascination with sensors as an electronics concept began with small pamphlet electronics instruction books from Forrest Mims [0] found at Radio Shack though they are widely available online these days. [1] if interested in programming microcontrollers though have not been introduced via non-computer breadboard electronics, it may be of interest to look at and learn from circuits in these notebooks, which provide basic concepts for how the circuits work and the principles they involve. for a technical person it could be instructive, for those like myself with a mental gap in the fundamentals there may still be questions that need to be answered before able to access and intuitively understand exactly what is going on, modifying it from there so, engineering mindset, great resource. artistic mindset, perhaps still a significant boundary before understanding though i have trouble with reading and ambiguous concepts so it could be only my limitation that kept me from learning the basics of electronics in terms of circuitry. another is: having the parts that are needed, versus just looking at the diagrams and understanding what is happening, or using these for reference, to build other circuits via same approach or extending or borrowing certain parts of designs. quite interesting to locate a Mims book on sensors and piezo kit together in regard to ongoing issues with piezo sensors and energy harvesting. [2] what captured my imagination was the particular notebook on sensors, their conceptual nature as this relates to issues of feedback and intelligence that effectively maps onto switches and gauges as measurements of activity, indicators of events; likewise, the reversibility of sensors, how some if not many can be inverted in their functioning, such that a microphone can be a speaker and vice versa PVDF piezo film as a sensor material exemplifies the tremendous range that a given material and its properties can connect with, in varying dynamics and dimensions. (if not mistaken, it can even detect airflow while potentially creating air flow likewise) and so one of these unique properties of piezo film is that it can detect temperature differences. this got me wondering (reading of its application in the tech manual), that given its incredible sensitivity, would it be able to detect electromagnetic fields due to the gradiated change in radiation levels surrounding wires, in proximity to EMF signals this combined with the idea of the PVDF sensor as an ANTENNA then had me wondering if this could function in a similar realm as the standard linear Hall effect sensor [3] that senses magnetic fields and functions as a strain gage (analog) or on/off switch (binary/digital) in the presence of electromagnetic fields. and thus EMF meters, most presumably, utilized Hall effect sensors that have multiple axes, 1-axis to 3-axis that relate to the geometry of the EM field in space, and thus rotating a probe for an EMF meter in a given context which generate varying signal, helping define the shape and direction of the signal, as it is positioned in space [4] [5] so my thinking was as follows... there are these small piezo sensor 'film tabs' that can be hooked up to a speaker, and if they could detect signals from home wiring in the wall, as a microphone, then essentially it approximates an EMF meter without the display details, though could indicate an intensity level by how loud or soft the noise that is picked up. perhaps this is actually not possible though it my questioning of its use. and this could require holding or moving the piezo film tab, the rectangle with an audio cable connected to it, then connected with a small preamp/mixer, amplifier or headphones, and perhaps moving it along the wall -- which seems unlikely due to sensitivity -- because it would generate massive noise seemingly, or, to potentially move it in the air, likewise that could seemingly make lots of noise by its movement, masking any other signals. it seems to go nowhere as an approach, yet my question remains that if this PVDF material can and does function as an antenna and it could pick up signals via vibrations, that perhaps if it was held or moved against a wall with electrical wiring inside, it could access this intense vibrational activity in some way it is obviously unclear as an approach, as multiple aspects coincide, both in attempting to access a signal and how this could occur... and thus: the issue could be having the PVDF film tab register 'temperature variation' as a way to monitor the difference in heat between a less electromagnetic realm and more electromagnetic realm as the radiation is monitored by the sensor and is this possible or not. and further, would the fact that the device is a capacitor then influence its charge via induction, such that the EMFs would charge the PVDF film, again via vibration or heat, though which could be used as electricity in a circuit it connects to, via energy harvesting. the concept is that the EMF meter as device would generate power when detecting signals. and so the existing rectangular film tabs [6] are potentially one way of going about this, in terms of 'mapping temperature' as mapping of EMFs, and seemingly related to this is the issue of the sensor being shielded or not, as this potentially relates to issues of tuning. what frequency or temperature range can influence the sensor a hypothetical application the PVDF sensor used for mapping out EMFs, is that a cellphone could contain such a device and be held against the wall or on a shelf in which there is electrical wiring, and the induction that occurs from the wires to the capacitor via vibration of EMFs could in effect provide charging power to the cellphone or other once-battery-reliant device, if energy harvesting was paired with wiring in the home and electrical power already in place, it would be an issue of locating it, excavating a hidden environment, so the EMF meter as indicator of signal strength or of radiation levels as temperature could provide a diagnostic of a local area via mapping it out as EM environment, and then situate devices in this specific location, in proximity to wires to maximize energy harvest via vibration that perpetually charges the capacitor (note here: if the PVDF film were etched as was previously mentioned with further patterning, this could massively increase voltage potentially, via increasingly its capacitance or storage capacity for holding energy, seemingly of higher voltage) though what really got my mind spinning was the idea of another format for this piezo polymer and that is 'piezo coaxial cable'. [7] [8] in that, this idea of PVDF as an antenna then is tending towards a shape or form that has been used for antennas, that is: a length of wire that picks up signals as wavelengths geometrically align with, map onto, influence its properties. (that is, if not mistaken in how things work) and so my mind starts thinking of making a loop out of this cable, as if a transponder that is used to track some emitting signal, or as a certain type of TV console antenna even, if not rabbit ears in retrospect. and what is the actual difference in these different materials functioning, plain metal and piezo polymer, in terms of antenna the obvious is that the latter generates power if it begins to vibrate. and holds onto it as a capacitor, so it builds up and stores the external influence. though more, consider the issue of high-voltage, that a long length of wire could potentially hold a lot of charge. and this in a context of sensing... there is the classic example of 'wireless power' in a person holding fluorescent tube lights under the powerlines of a high-voltage pylon corridor that in turn illuminates the lights via EMFs by way of the surrounding intense levels of radiation that bathe the area in proximity to such towers so there is massive energy in the air, ionizing it, around high voltage electric transmission towers, enough to light a fluorescent (AC) lightbulb that otherwise requires a ballast/transformer to do so (again, if not mistaken), in that charge/electrons are rapidly moving back and forth through a gas held inside the unlit tube that then generates light by triggering a reaction that releases or produces photons via the current shooting through the gas (sidenote: LEDs interesting in similar way, light or photons produced by jumping gap in a circuit) note: DANGER: DO NOT ATTEMPT TO DO THIS WITHOUT PROPER EXPERTISE/QUALIFICATIONS... now imagine you have a loop of piezo coaxial cable that can function as an antenna. potentially and-or seemingly, it would be able to 'read' the temperature difference via the radiation in the area underneath or nearby similar high-voltage towers. though this may co-exist as a variable with frequency/vibration thus heat may just be another way of saying the same thing, though in a more tangible or perceivable way, in that its influence may be more apparent. here is why it is not advisable for a do-it-yourselfer- because any length of this piezo cable is a capacitor that can store energy, and the larger the cable the more voltage that could be stored, it would appear, and thus if such an antenna were use and capable of storing large amounts of high voltage charge, it then could be deadly dangerous to be holding onto this cable because it would be inducing current from the powerlines and potentially into the body, in terms of its grounding (say, straight through an arm to heart then out one foot or both) potentially like getting hit by lightning. any precautions that would be taken by electrical workers that work on high voltage lines would be relevant as security precautions for any such experimentation. and yet, if a circuit were made around such an antenna -- potentially via paired or matching VIBRATION alone, this same piezo cable device could potentially provide much more power and current via its energy harvesting. (or so it is speculated here) in a more removed situation, or a smaller antenna, it could potentially be used to map EMFs via piezo wire in the way Hall effect sensors are used today, though again with the benefit of energy harvesting and providing power to circuitry. thus piezo cable, as antenna, could have its own unique attributes and properties that could better align in certain situations or circumstances to provide power or function as an antenna, whereby the 'microphone' or listening is occurring in a vibrational realm that is not connected to material vibration beyond its own support structure, instead, as antenna it is tuning into strong fields (as heat, here proposed) that would potentially be capable of providing this source of vibrational needed to power circuitry, yet further, also a signal of meaning about the nature of the environment in its electromagnetic composition and ordering, mapping or direction based on these attributes, features of landscape that is relevant in terms of health and energy so then i was done with thinking about it and then encountered a photograph that inspired another layer of thinking within this domain... it was of a woman's hat [9] created by a fashion designer that spoke to these issues in terms of its language and aesthetics, providing insight into the nature of the questions involved. what if, for instance, the piezo film tab sensors were able to monitor the heat or radiation as this correlates to vibrational frequencies of cellphones as they are held against the skull, and evaluate the radiation involved at the blood-brain barrier as this influences tumor development in humans via sending this transmission of cellphone signals from the phone to the cellular towers? in other words, what if this little sensor could be placed on a hat, alongside the surface of the skin, and register and monitor the radiation levels from omnidirectional antennas shooting EMFs and coded patterns into the human brain, as part of this relation between people, tools, technology and infrastructure - "daily ~communionication" again, the wonders of the piezo film indicate that they do respond to monitoring of skin, and thus likely a viable approach to modeling this relation, and testing against "official evidence" about how these antennas and vibrations are influencing the human physiology. real-time cellphone monitoring (another approach could involve a PVDF sensor at the only opening of an otherwise EMF-opaque box or container that has a cellphone in it, attempting to transmit or radiate its signal, and measuring activity via vibration or heat from this at various distances) additional hats provided further insight into aspects of multiple tunings [10] via adjusting cantilevers or tuning forks, to what frequencies are related to and through, as part of consciousness as information, this in a non-electromagnetic framework seemingly. and also of the nature of the mind being targeted by hostile signaling [11] in these toxic domains of the technical wilderness, functioning against humanity. in that disease and illness correlate with these same issues as they remain ignored and unaddressed, and allowing continuing abuse of power based on hidden leverage that results from no checks and balances upon unrestrained technological development for private goals and agendas, against public interest the kicker is that such technology could already be deployed in a hidden framework or context, just as it is hard to imagine ubiquitous mass surveillance via technological infrastructure without this corresponding in some significant way to a paid informant network on the ground, in close proximity, allowing full spectrum monitoring that tends towards gossip as power that is exploited in the political bias within infrastructure, emperor no clothes policy laid bare via own tattle tales thus, what if likewise, the potential for such sensing as harvesting of free energy already exists yet remains in a realm of secrecy, leveraged against populations on the outside of this inner society. what if different truths exist that remain unaccounted for, different economics that then become the basis for exploitation via illusion, via not sharing the discoveries and using this for power, to take over domains via ruse, deception, ill-intent, etc in other words: the conspiracy revealed, now out in the open... take for instance the unusual aesthetics of a local substation for electric power 'delivery', like a router, bus, or hub that then transforms the voltage en route to its destination. under the ordinary or standard model of power distribution, this could be assumed to function in one way and one way only... powerplant ==> transmission towers ==> substation ==> distribution poles that is, the power is generated at a power station, moved through high-voltage cables suspended from towers to a substation, where this power is stepped down and then further distributed via wooden poles to various dwellings though 'the antennas' could be for lightning protection, it seems highly unusual to have a large array of them or at least this design approach has not yet been encountered before this, and calls into question what is new about it. i had previously speculated it was a free energy substation tapping into atmospheric electricity via the antennas, though until the PVDF sensors did not understand how this might be possible. in fact, thinking about it right now, combining piezo antennas with HAARP atmospheric injections of frequency is potentially the model for remote power delivery at national or international scale, ala Nikola Telsa's Wardenclyffe Tower [13] in this scenario, the substation would be the 'generator' in that it could tune into a given vibration (perhaps Schumann resonance) and create high voltage electricity on-site, via remote transfer of energy -as information- seemingly, outside an electromagnetic context yet tied back into it via properties of nature, its order. in this way, power delivery could begin at the substation locally, then distribute back outwards to both high-voltage lines and the reduced-voltage distribution poles, from the substation itself, a decentralized power generation and delivery system, in effect, locally, though harmonized at a larger scale via atmospheric electricity as the generator or transmitter of 'motive power', if not conceptualizing this in error. that would be the illusion, that the powerplant is sending the power and not substation substation ==> transmission/distribution ==> local power thus like a crystal oscillator functioning in reverse as piezo sensor, if 'free energy' were being harvested at the substation-level, then a different organization of these relations exists than what is said to exist and used as a basis for top-down power structures in society. a decentralized, distributed, non-toxic energy that is limitless versus an infrastructure based on oil and gasoline and goal and nuclear energy that is destructive, basically raping the earth and likewise its inhabitants to fuel a given insane development strategy functioning against humanity as this aligns with 'green politics' and 'environmentalism', its politics and moral agenda within what is a warped accounting for various such factors. in other words, perhaps battery power is only an issue for those on the outside of this. if it indeed were to exist as a parallel infrastructure in the everyday environment. and maybe that is being used as leverage, a secret hidden development with different economics, social dynamics, and political goals that are not 'represented' in existing language, instead functioning outside or beyond its limiting frameworks and outdated views and beliefs, which provide cover and camouflage for sustaining trickery, exploiting it, and securing its place in relation to the rogue world state, thoroughly invested in its mission to serve its hidden special interests, having divested humanity long ago for private rewards in doing so. wouldn't it be nice to see a circuit diagram of how those antennas are hooked up at the substation. really interesting if it involved more than 'ground' and instead was part of a piezo-based energy harvesting engine capable of generating constant high-voltage power, for instance. and who would the power to such oversight to occur within society? seemingly nobody. that is the entirety of the situation right there- *game over* (...as if anything was ever was that simple) 0.
