Description

technical field [0001] The invention relates to the field of electronic devices, in particular to a material used for the preparation of zinc oxide piezoresistors. Background technique [0002] The varistor is a voltage limiting protection device. Utilizing the nonlinear characteristics of the varistor, when an overvoltage occurs between the two poles of the varistor, the varistor can clamp the voltage to a relatively fixed voltage value, thereby realizing the protection of the subsequent circuit. In recent years, with the rapid development of information technology, the miniaturization, multi-function, and high stability of electronic equipment have become an inevitable trend of development, and the varistor as a protective semiconductor element is also correspondingly moving towards thinner, lower voltage, and higher reliability. sexual development. [0003] Zinc oxide varistors have been widely used because of their simple process, low cost, and convenient use. But now...
