Abstract
The present disclosure provides an electrostatic self-powered strain grid sensor configured to measure strain of a component to be measured. The sensor includes a slide groove and a slide sheet. The slide groove is fixed to a fixing end and a sensor array is arranged at an inside bottom of the slide groove. The slide sheet is fixedly connected with the component to be measured and a lower end part of the slide sheet is in contact with the inside bottom of the slide groove. An electric signal is output when the slide sheet sweeps over the sensor array. Based on the output current of a sensor unit of the sensor array indicated by the signal, the number of segments swept over by the slide sheet and a distance swept over the sensor units in a single sensor array by the slide sheet is obtained, thereby acquiring a structural strain.
