Energy Harvesting PMICs
What is Energy Harvesting?
Energy harvesting is the process of collecting, or harvesting, minute amounts of unharnessed energy from the surrounding environment, including light and vibration, and converting these to electricity. Energy harvesting is expected to be used as a power source in sensor nodes for wireless sensor networks, among other potential applications, thereby contributing to the realization of a low-carbon society.
These new products will contribute to new battery-free technologies in areas such as energy management for homes and buildings as well as wireless sensor networks for farms, and will also lead to longer battery lives for portable devices.
