  • Abstract
    Infrared and Ultrasonic sensors have been fabricated by using ferroelectric thin films on diaphragms of Si wafer. Si membranes plays as thermally isolated substrate in the infrared sensor and vibrating substrate in the ultrasonic sensor. Infrared and positional image can be obtained by using their sensor arrays.
