Abstract
The present disclosure provides systems and methods implemented using physical property sensors. A physical/property sensor includes a sensor coil configured to wirelessly communicate with an external interrogator, an analog front end communicatively coupled to the sensor coil, a microcontroller communicatively coupled to the analog front end, and a physical property sensing element, wherein the microcontroller is configured to generate a digitally modulated electrical signal based on signals generated by the physical property sensing element, and wherein the analog front end is configured to forward the digitally modulated electrical signal to the sensor coil for transmission to the external interrogator.
