摘要

纵向(“RIBBIE”)形式的剪切放大传感器已经测试了放大的d/sub / 15/响应。机械放大的挠性扭曲系统可以通过将器件上的压缩应力传递到电陶瓷元件上的横向剪切来提高d/sub h/g/sub h/优值。这种类型的放大系统在机械上被归类为扭曲的，因此没有体积变化。通过将静水应力转化为横向应变，横向力可以用来产生剪切应变并激活d/sub 15/系数。电极沿传感元件的两侧放置。对挠性扭曲器件进行测试，以检查其性能中的灵敏度极限。

Flexi-distortional piezoelectric sensor results

A longitudinal ("RIBBIE") form of a shear amplification sensor has been tested for amplified d/sub 15/ response. The mechanically amplified flexi-distortional system may improve the d/sub h/g/sub h/ figure of merit by transferring the compressional stress on the device to a lateral shear on the electroceramic element. This type of amplified system is mechanically classified as distortional and, therefore, without volume change By transforming the hydrostatic stress to transverse strain, the transverse forces can be used to develop shear strain and activate the d/sub 15/ coefficient. Electrodes are placed along the sides of the sensing element. Flexi-distortional devices are tested in order to check for the limits of sensitivity in their performance.
