A Shear-Mode Piezoelectric Heterostructure for Electric Current Sensing in Electric Power Grids

This paper presents a shear-mode piezoelectric current sensing device for two-wire power cords in electric power grids. The piezoelectric heterostructure consists of a cymbal structure and a permalloy plate. The cymbal structure is constructed from a permanent magnet, a brass cap, and shear-mode pie...
