Adaptive Power Management for Energy Harvesting Embedded Systems

WithJun Lu, Shaobo Liu, Qing Wu, Qinru Qiu

Real-time embedded systems (RTES) have wide applications from sensor networks, personal communication, and entertainment devices to control and management units of unmanned vehicles. Renewable energy is energy generated from natural resources such as sunlight, wind, rain, tides geothermal heat, which are naturally replenished. Energy harvesting, also called energy scavenging, refers to the process of collecting and converting renewable energy to be utilized by electronic systems. It is a promising technology for overcoming the energy limitations of battery-powered systems and has the potential to allow systems to achieve energy autonomy. Recently, great interest has risen in powering RTES with renewable energy sources.
