    • 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.

    • 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.
    • 波段成像器包括利用具有热致动双压电晶片结构的光子隧穿将红外辐射转换成可见光的成像像素。 红外线辐射通过透明基板并被由像素板形成的双压电晶片吸收。 该吸收产生热量,其使双压电晶片结构和像素板朝向衬底偏转成由通过衬底传播的光产生的瞬逝电场。 将双压电晶片结构和像素板穿透到瞬逝电场允许通过衬底传播的可见波长的一部分穿过衬底,双晶片结构和/或像素板,作为与入射强度成比例的可见光辐射 红外辐射。 该转换的可见光可以叠加在通过成像像素的可见波长上。
