| 摘 要： | 本文设计了一种新型的金属—压电陶瓷结构的触觉传感器.由于具有月牙状浅穴的作用.可将z方向的应力转变成很大的径向应力.因此在d_k中d_(33)与d_(31)不再是相减,而是相加,因而传感器的灵敏度大大提高.这种结构的传感器制作简单,成本低廉,具有极强的耐磨性和耐冲击性,且动态范围宽,可靠性强等特点.

| Abstract: | A new type of tactile sensor composed of metal(brass) end caps and piezoelectric ceramic is described in this paper. A shallow cavity called'moonie'between PZT ceramic and thick metallic electrode is designed to convert a portion of z-direction stress into a large radial and tangential stress of opposite sign, thereby causing the d33 and d31 contribution to d to add rather than subtraction. The construction is simple,in-expensive,robust,and likely to have very high reliability. |
