    Abstract: A pyroelectric thermal energy harvesting apparatus for generating an electric current includes a cantilevered layered pyroelectric capacitor extending between a first surface and a second surface, where the first surface includes a temperature difference from the second surface. The layered pyroelectric capacitor includes a conductive, bimetal top electrode layer, an intermediate pyroelectric dielectric layer and a conductive bottom electrode layer. In addition, a pair of proof masses is affixed at a distal end of the layered pyroelectric capacitor to face the first surface and the second surface, wherein the proof masses oscillate between the first surface and the second surface such that a pyroelectric current is generated in the pyroelectric capacitor due to temperature cycling when the proof masses alternately contact the first surface and the second surface.

    Abstract: A waveband imager includes an imaging pixel that utilizes photon tunneling with a thermally actuated bimorph structure to convert infrared radiation to visible radiation. Infrared radiation passes through a transparent substrate and is absorbed by a bimorph structure formed with a pixel plate. The absorption generates heat which deflects the bimorph structure and pixel plate towards the substrate and into an evanescent electric field generated by light propagating through the substrate. Penetration of the bimorph structure and pixel plate into the evanescent electric field allows a portion of the visible wavelengths propagating through the substrate to tunnel through the substrate, bimorph structure, and/or pixel plate as visible radiation that is proportional to the intensity of the incident infrared radiation. This converted visible radiation may be superimposed over visible wavelengths passed through the imaging pixel.

    Abstract: An electromagnetic radiation sensor that exhibits improved performance by virtue of an ability to tune its sensitivity is disclosed. The electromagnetic radiation sensor incorporates thermal actuators that act in opposition to one another, but which have a slight difference in responsivity. A temperature controller is used to tune the sensitivity of the electromagnetic radiation sensor by controlling the temperature of the substrate on which the sensor is formed.

    Abstract: A radiation sensor array that exhibits improved performance is disclosed. The radiation sensor array dissipates kinetic energy within a capacitive sensing element and establishes an electric field across a two capacitor bridge circuit that comprises the capacitive sensing element, wherein the electric field has substantially constant magnitude during both sensing and reset modes of operation. The electric field, however, has opposite polarity during the sense and reset modes.

    Abstract: Highly efficient binary and ternary gas mixtures for use in diffuse glow discharge closing switches are disclosed. The binary mixtures are combinations of helium or neon and selected perfluorides. The ternary mixtures are combinations of helium, neon, or argon, a selected perfluoride, and a small amount of gas that exhibits enhanced ionization characteristics. These mixtures are shown to be the optimum choices for use in diffuse glow discharge closing switches by virtue of the combined physio-electric properties of the mixture components.
