METHODS, DEVICES AND SYSTEMS FOR SELF CHARGING SENSORS

摘要

Methods, systems and devices for an energy harvesting sensor are disclosed. A sensor device may include an energy harvesting element configured to harvest energy from a source of energy that is to be measured by the sensor device, and an energy storage element configured to store energy generated by the energy harvesting element. The sensor device may further include a transmitter circuit coupled to the energy storage element and configured to transmit a wireless signal when the energy stored in the energy storage element is sufficient to power a transmission of the wireless signal. The time between transmissions by the transmitter may be used by a receiver of those transmissions to calculate a measure of the quantity being used for energy harvesting.
