ENERGY HARVESTING FOR WIRELESS SUBJECT MONITORING SENSOR

A sensor apparatus configured to detect at least one physiological parameter of a subject includes a sensor that detects at least one physiological parameter of the subject as sensor data. An energy harvesting circuit includes a plurality of energy harvesting devices configured to harvest ambient energy from an environment of the subject. The energy harvesting devices generate power at a plurality of voltage potential levels from ambient energy. A conditioning circuit is configured to adjust the plurality of voltage potential levels to a bus voltage supplied to a supply bus. A controller receives operating power via the supply bus and controls the activation of the sensor and the wireless communication circuit.
