FRICTION GENERATOR AND VIBRATION SENSOR USING DIPOLYMER COMPOSITE FILM AND PREPARATION METHOD THEREFOR

摘要

Provided are a friction generator and a vibration sensor using a dipolymer composite film and a preparation method therefor. The friction generator using a dipolymer composite film comprises a first electrode layer, a first macromolecular polymer insulating layer and a second electrode layer which are all arranged in a stacked manner, wherein the material adopted for the first macromolecular polymer insulating layer is the dipolymer composite film. A frame structure capable of vibration is arranged between the first macromolecular polymer insulating layer and the second electrode layer of the vibration sensor or between the first macromolecular polymer insulating layer and a second macromolecular polymer insulating layer. An intermediate electrode layer or an intermediate thin film layer may also be further added between the first macromolecular polymer insulating layer and the second macromolecular polymer insulating layer, and the frame structure capable of vibration may be formed between every two of these layers. The friction generator and the vibration sensor using a dipolymer composite film can improve vibration performance and acoustic sensing performance remarkably and have outstanding low-frequency response performance.
