Most embedded devices and remote sensors are powered by batteries. Yet, lifespan of the batteries is limited to few years. To eliminate costly battery replacements issues, especially when it is impractical or dangerous, energy harvesting technologies provide unique opportunity for unlimited operating life of low power devices.
Energy harvesting offers an alternative source of usable electrical power by capture and conversion of available energy in the environment. Activities in our research group enable self-powered and independent energy systems for predictive maintenance by generation of electrical energy from low-thermal energy, vibration, light and kinetic energy.
