E-peas' RF energy harvesting IC solution - AEM40940 - is the next generation integrated energy management subsystem integrating a rectifier that extracts AC power from ambient RF waves to simultaneously store energy in a rechargeable element and supply the system with two independent regulated voltages. This allows product designers and engineers to extend battery lifetime and ultimately get rid of the primary energy storage element in a large range of wireless applications like industrial monitoring, home automation, wearables.
