PROCESS FOR MANUFACTURING AN ACOUSTIC SENSOR WITH AN ESSENTIALLY NON-DETACHABLE PROTECTIVE LAYER, AND ACOUSTIC SENSOR SO OBTAINED. |
摘要 |
<p>The invention relates to a method for manufacturing an acoustic sensor, and also to the sensor. The sensor comprises a piezoelectric sheet (12) mounted on a support (14) and electrically connected to electrodes (16,18) connected by electrical conductors (20,22) to a measurement device, characterized in that the assembly constituted by the sheet (12) and its support (14) is coated with a one-piece polymerizable coating layer (24) which is preferably electrically insulating, such that the portion (24a) of the coating layer (24) overlying the sheet (12) constitutes a protective layer which is rendered non-detachable or essentially non-detachable from the piezoelectric sheet (12). The method for manufacturing this sensor is extremely simple and inexpensive, and the protective layer is non-detachable.</p> |
