  • Abstract
    The use of a dual layer transducer as a touch sensor has been explored both through experiments on simple prototypes, and FEM modeling. An adhesive free method was developed to deposit piezoelectric P(VDF-TrFE) polymer directly onto a standard Kapton (polyimide) film yielding touch sensors with good acoustic response in the ultrasonic band between 40 MHz to 60 MHz.
