Abstract
A passive acoustic sensor circuit and related wireless sensing system are provided. The passive acoustic sensor circuit is configured to induce an electrical current in response to receiving a radio frequency signal. The passive acoustic sensor circuit includes a sensor circuit, which can detect a sensory event (e.g., a touch or key press) and cause a variation in the electrical current in response to the sensory event. In contrast, the sensor circuit will not cause the variation in the electrical current in absence of the sensory event. In this regard, the presence or absence of the current variation, which can be detected remotely and wirelessly, will serve as an indication of the sensory event. By detecting the current variation remotely and wirelessly, it is possible to reduce physical wiring in an electronic device (e.g., smartphone, smartwatch, etc.) to help reduce design and manufacturing complexity of the electronic device.
