Abstract: An infrared imager includes an array of capacitance sensors that operate at room temperature. Each infrared capacitance sensor is composed of a bi-material strip (110) which changes the position of one plate (100) of a sensing capacitor in response to temperature changes due to absorbed incident thermal radiation. The bi-material strip (110) is composed of two materials with a large difference in thermal expansion coefficients.
