Your Amazon Echo has a hidden motion sensor feature that allows you to do some pretty cool stuff, from switching on lights to setting alerts for intruders.

The piezoelectric sensor works at extremely high temperatures. Source: University of Houston Sensors operating in nuclear reactors, geothermal wells, petrochemical plants and other harsh industrial ...

The purpose of a piezoelectric sensor is to measure the vibratory movements of structures by the direct effect of the piezoelectric material. In this paper, the operating principle of the ...

Monitoring extreme environments requires a sensor continues to work in high temperatures. Now, researchers have developed a piezoelectric sensor that operates reliably at the temperature of ...

2 Sensor test principle The sensor is mainly composed of two parts coupled with piezoelectric material and piezoresistive material. Due to the inverse piezoelectric effect, the dimensional changes in ...

In this article, a novel sensing structure is proposed to measure tensile loading. The sensing structure is motivated by the operating principle of the tendon. The fibroelastic characteristic of the ...

A monitoring system using a piezoelectric sensor was developed for the quantitative analysis of the stirring process in which a mixture of a thickener with water was prepared. A thin piezoelectric ...
