    • Abstract
  • One piece of piezoelectric-film of ferroelectret polypropylene is piled up to make a sensor by encapsulation.An amplifier is designed to enhance the output signal, then direct the amplified signal to a wireless transmitter, and a wireless receptor is contacted to a signal-processing module.This kind of wireless sensor can be used for alarming and activity monitoring.
