Voltage Sensor utilizing Inverse piezoelectric effect and Fiber Grating

A voltage sensor based on inverse piezoelectric effect and fiber gratings is presented in this paper. Besides basic sensor validation test of working frequency signals, two sensors with similar parameters were tested and analyzed with working frequency signals and operation voltage signals. Test results indicate that the sensor can work well in working frequency but can only respond to part of the operation voltage signal properly. This is a potential passive sensor consist of the piezoelectric element and fiber element, more work should be conducted to enlarge its working frequency range.
