Patent abstract
A pressure sensitive acoustic wave sensor and actuator include an acoustic wave cavity foπned in a substrate, a transducer generating an acoustic wave substantially trapped in the acoustic wave cavity and an acoustic wave absorbing member that absorbs more acoustic wave energy in the acoustic wave cavity in response to increased pressure on the member. The speed and/or braking of an electric vehicle is controlled through operator input of a foot pedal, using the pressure sensitive acoustic wave sensor.
