A generalized parity-time (PT)-symmetric telemetric sensing technique, which enables new mechanisms to manipulate radio frequency (RF) interrogation between the sensor and the reader, in order to boost the effective Q-factor and sensitivity of wireless microsensors was theoretically proposed and experimentally shown. This sensing technique which used MEMS-based wireless pressure sensors operating in the radio-frequency spectrum, overcame the long-standing challenge of implementing a miniature wireless microsensor with high spectral resolution and high sensitivity, and opened opportunities to develop loss-immune high-performance sensors, due to gain-loss interactions via inductive coupling and eigenfrequency bifurcation resulting from the PT (PTX)-symmetry. It was shown that a real and constant eigenfrequency in specific higher-order of the generalized PT-symmetric electronic systems was exploited to realize a robust wireless power transfer platform locked to the frequency of operation. This PT system, provided breakthrough in dynamic and alignment-free wireless charging technology with extended range wireless charging and sensing at the same time.
