Energy Harvesting
Energy harvesting is the process of capturing and converting ambient energy from the environment into usable electrical power for small electronic devices, such as sensors, wearables, and IoT nodes. It enables self-sustaining systems by eliminating the need for batteries or wired power sources, drawing from sources like solar, thermal, vibration, or RF energy. This technology is key to powering low-energy devices in remote or inaccessible locations.
Developers should learn energy harvesting when designing IoT systems, wireless sensor networks, or wearable devices that require long-term, maintenance-free operation, such as environmental monitoring or smart agriculture. It's essential for applications where battery replacement is impractical or costly, and for sustainable, energy-efficient solutions in edge computing and embedded systems.
