Wireless power transfer to embedded sensors

摘要

In certain embodiments of the present disclosure, a wireless sensor system is described. The wireless sensor system includes a near-field wireless power transfer component, at least one measurement sensor, and an antenna. The antenna is in communication with the measurement sensor and can transmit measurements from the measurement sensor. The near-field wireless power transfer component can wirelessly receive power to operate the measurement sensor.
