Absrracr-The piezoelectric polymer polyvinylidene fluoride (PVF2) has recently shown great promise in medical imaging applications when combined with integrated circuit technology to form a broadband acoustic detector. The application of polyvinylidene fluoride as a generator of acoustic energy in the 1-10 MHz frequency range is considered. The acoustic response of rigidly backed PVFz to voltage and current-source electrical drive is analyzed, and the broadband nature of the response to current… CONTINUE READING
