Piezoceramic bending transducer and use thereof |
摘要 |
A piezoelectric bending transducer includes a support body, a stack of piezo-ceramic layers, arranged thereon and flat electrodes arranged between the layers. On the side of the support body facing the stack, an adaptation layer is arranged with essentially the same coefficient of expansion as the piezo-ceramic. The bending transducer displays a good actuating power and a low thermal natural distortion with economical production costs. The transducer is particularly suitable for application in a valve.
