抄録

A flexible strain sensor based on a unique ZnO microwire network structure was constructed in this work. The current characteristics of the sensor were investigated by applying tensile and compressive static strains, and the sensor showed quick current response properties. Moreover, the sensor exhibited excellent response properties to the periodic microstrain with 1.0 and 0.2 Hz frequencies. The unique piezoelectric and piezoresistance of ZnO resulted in the sensor had excellent sensing performance to microstrains. The highest gauge factor of the sensor was up to 900. The results provide a new design method for high-performance microstrain sensors based on piezoelectric materials.
