A study on MicroCantilever Deflection for the Infrared Image Sensor using Bimetal Structure


Article Preview

This is a widespread requirement for low cost lightweight thermal imaging sensors for both military and civilian applications. The feasibility of micromechanical optical and infrared (IR) detection using microcantilevers is demonstrated. Microcantilevers provide a simple Structurefor developing single- and multi-element sensors for visible and infrared radiation that are smaller, more sensitive and lower in cost than quantum or thermal detectors. Microcantilevers coated with a heat absorbing layer undergo bending due to the differential stress originating from the bimetallic effect. This paper reports a micromachined silicon uncooled thermal imager intended for applications in automated process control.
