日本村田制作所利用压电陶瓷研制出一种可以测量动态压力的新型接触压力分布传感器.这种传感器是由敏感部分和控制部分组成的.敏感部分的压电元件排成矩阵形,以最小为25μs的时间间隔,最多为255次连续地测量在上述矩阵形压电元件区移动的物体的接触压力,然后把测得的数据存贮在计算机的存贮器中,形成以压力一时间特性为输出信号的系统.每个压片元件都是一个边长为1cm的正方形陶瓷片,它可以测量10~4～10~8Pa的压力. Japan’s Murata Manufacturing Co., Ltd. developed a new type of contact pressure distribution sensor that can measure dynamic pressure using piezoelectric ceramics. The sensor consists of a sensitive part and a control part. The sensitive parts of the piezoelectric elements are arranged in a matrix shape with a minimum of 25 μs, up to 255 times, the contact pressure of an object moving in the above-mentioned matrix-shaped piezoelectric element area is continuously measured, and then the measured data is stored in the memory of the computer to form a signal having a pressure-time characteristic of System for outputting signals Each tabletting element is a square ceramic piece with a side length of 1 cm, which can measure the pressure of 10 ~ 4 ~ 10 ~ 8Pa.
