Abstract
A bolometer type ultra-sensitive silicon sensor pixel of a multi-pixel sensor wherein each pixel includes a detector stage, an intermediate stage, and a heat bath stage. The detector stage, the intermediate stage and a portion of the heat bath stage are generally co-planar and are interconnected by I-beam bridges so as to permit mutually co-planar rotation in response to stress and strain. Electrical coupling is improved between a micro-antenna and the detector stage by a two stage transformer assembly that couples the micro-antenna to the detector stage.
