| 摘要 |
A film (10) of a polymeric piezoeletric material such as polyvinylidene fluoride is connected to an external circuit (18) without the use of any electrically conductive connection to the film (10). Conductive elements (14) are spaced from the film (10) by a dielectric material (12), conveniently in the form of an adhesive which also secures these members together. In preferred embodiments, the elements (14) are mechanically compliant, such as conductive cloth or foam. |
