Abstract: Zero-power system for remote monitoring of heat sources is provided. The systems detect failure indicators of remote equipment including power substations, oil rigs, large inaccessible machinery in a factory, and communications equipment. The systems also can be used to detect the presence of people in buildings or in other locations, so as to improve HVAC utilization in large buildings. When the zero-power monitoring systems detect heat sources, such as the presence of people, failure indicators, or a targeted environmental signal, a circuit is closed using the energy of the detected radiation, and activating an RFID tag, a radio transmitter, or an alarm. The monitoring systems can remain deployed and active for many years without the need for battery replacement.

Abstract: A resonator includes a piezoelectric plate and interdigitated electrode(s). The interdigitated electrode includes a plurality of conductive strips disposed over a top surface of the piezoelectric plate. A two-dimensional mode of mechanical vibration is excited in a cross sectional plane of the piezoelectric plate in response to an alternating voltage applied through the interdigitated electrode. The two-dimensional mode of mechanical vibration is a cross-sectional Lamé mode resonance (CLMR) or a degenerate cross-sectional Lamé mode resonance (dCLMR).

Abstract: Zero power wireless sensors, devices, and systems are used for crop water content monitoring. The sensors consume no power while monitoring for the presence of dry crop conditions. Infrared reflectance from plants is measured and when selected spectral conditions are met, a circuit is closed, activating an alarm, an RFID tag, or a radio transmitter. The deployed sensors consume no power while monitoring, reducing or eliminating the need to change batteries.

Abstract: A zero-power plasmonic microelectromechanical system (MEMS) device is capable of specifically sensing electromagnetic radiation and performing signal processing operations. Such devices are highly sensitive relays that consume no more than 10 nW of power, utilizing the energy in detected electromagnetic radiation to detect and discriminate a target without the need of any additional power source. The devices can continuously monitor an environment and wake up an electronic circuit upon detection of a specific trigger signature of electromagnetic radiation, such as vehicular exhaust, gunfire, an explosion, a fire, a human or animal, and a variety of sources of radiation from the ultraviolet to visible light, to infrared, to terahertz radiation.
