N2 - Wireless transmission systems fed by ambient harvested energy power sources can operate continuously, without needing battery replacement. Such systems are ideal for applications with limited or difficult accessibility. Ambient energy sources exhibit a stochastic nature, so an energy storage device must store the harvested energy. In this work, a control method that minimizes the use of storage is developed. The strategy is to match data transmission rate as close as possible to the availability of harvested power, so the energy storage capacity can be reduced. An audio recording sensor is designed and simulated using SPICE to validate the proposed controller. For this system, the size of storage device is reduced by a factor of 24.
