Abstract :
A calculation using the FEM (Finite Element Method) is employed for the design of electromagnetic devices and products made of composite polymer materials. Applications include the insulating materials of high voltage machines or cables, and sensor materials for the low frequency range. In this study, an acoustic sensor composed of a polymer electret membrane is designed using FEM. This sensor shows a good response in the low frequency range
