Energy Harvesting for Battery-less IoT Device Operation
This component project of the CIDR program explores a battery-less IoT device through multiple energy harvesting technologies. The environmental, economic, and logistical issue of battery replacement in the deployment of millions of IoT devices can be solved by utilizing super-cap instead of batteries. One possible solution for realizing these battery-less IoT devices is through multiple energy harvesting with design optimization of the circuit power consumption. Moreover, this project aimed to develop a customize and reconfigurable power management integrated circuit (IC) designed chip with different energy harvesting technologies; a combined or stand-alone energy harvesting unit (e.g., light, thermal, and RF sources), depending on the application of the wireless sensor node (WSN) or IoT device.
