Abstract :
Recently, the acoustic-impedance microscope has been developed by the application of pulsed electro-acoustic (PEA) method for the biomedical sample observation. The acoustic-impedance microscope can measure the difference of acoustic impedance in thickness direction in materials. When measuring the space charge distribution of a polymer insulating material by using the normal PEA method, the acoustic waves to obtain the space charge profile are detected by piezoelectric device in the system.
