  • Abstract
    The authors develop an acoustic emission sensor using a Ca-modified PbTiO3 ceramic-PVDF copolymer composite as piezoelectric element. The sensor´s experimental impedance and frequency bandwidth are determined and it is concluded that the device can operate over a large frequency range
