Abstract
A sensing system includes a sensor, a wireless transmission system, a wireless receiver system, and a controller. The sensor is configured to determine sensor data, the sensor data associated with a sensing environment. The wireless transmission system is configured to wirelessly couple with the sensor, the wireless transmission system configured for wirelessly providing significant electrical energy to the sensor as wireless power signals and receive the sensor data as in-band data signals encoded in the wireless power signals. The wireless receiver system is operatively associated with the sensor and with which the wireless transmission system couples with the sensor and is configured to receive the significant electrical energy as the wireless power signals from the wireless transmission system. The controller is operatively associated with the wireless transmission system and is configured to decode the in-band signals from the wireless power signals as the sensor data.
