Abstract
This work for the first time presents a wireless electric current sensor via integrating a magnetic-piezoelectric cantilever and a trapezoidal-structured microstrip antenna. The wireless current sensor system, consisting of both the magnetic-piezoelectric cantilever for measuring electric currents and the trapezoidal-structured microstrip antenna for transmitting output voltages, are designed and integrated for demonstration, at an operating frequency of 3 GHz with the lowest return loss. Although output errors of 2-7% are observed for output voltage range of 88-116 mV, the signal transmission measurement demonstrates that the proposed integration is experimentally feasible and effective. Owing to the ultra-wideband (2-11 GHz) and low-power consumption of the integrated microstrip antenna, the proposed integration is expected to be applicable to various kinds of wireless sensor nodes of different frequencies or multi-sensors monitoring systems.
