摘　　要：在分析了Z元件力敏效应的L型伏安特性的基础上,提出了一种利用Z元件构建的,可直接输出数字信号的力数字传感器的设计方案.选择了简支梁弯曲受力方式为Z元件的力载荷承受方式,解决了Z元件由于体积小、厚度薄、脆性大而带来的无法直接施加作用力的问题,实现了力敏现象向力敏效应的转化.首次提出了Z元件的晶格扭应变与等效电阻的微观机理的观点,并在此基础上论述了基于Z元件的力传感器的温漂补偿的必要性和补偿原则及方法.Structure of application circuit based the elements is the simplest. On the basis of brief analysis to essential characteristic of Z-elements, a novel force-sensitive sensors based on Z-elements is presented and designed that can directly produce digital output. Bending force is selected as the bearing pressure to force-sensitive Z-elements, a question is solved that direct force is not able to be applied on the Z-elements on account of small volume, thin thickness and high frangibility of the element. On the foundation of simple statement to microphysical principle of force-sensitive Z-elements presented first in this paper, it is advanced why and how to compensate temperature-drift of force-sensitive sensors based on Z-elements.
