METHOD FOR PRODUCING ELECTRET-CONTAINING DEVICES |
摘要 |
A new method for fabricating electret-containing devices is disclosed. The inventive method includes a new technique for fabricating electrets, which involves applying a voltage across an electrically polarizable body. Large-scale breakdown effects in the body are avoided by reducing the voltage across at least a portion of the body undergoing polarization in response to a current indicating the onset of a breakdown in the body. |
