+With wireless communication often comes an incentive for power source without need for external wires and power transmission network. Significant research has been made to alternative power sources for IoT devices from prevalent energy sources like light, vibration, temperature gradient and similar. Use of small solar panels with potential large capacitor seems to be the most viable out of these but there [tuzdroj].
