Sony Semiconductor Solutions Corporation (SSS) has developed an energy harvesting module that uses electromagnetic wave noise energy. The module, based on technology developed during tuner development, can generate power from electromagnetic wave noise with a high level of efficiency. This technology can utilize the constant electromagnetic wave noise generated by various electronic devices to power low-power consumption IoT sensors and communications equipment. SSS aims to incorporate this technology into a power circulation model to contribute to the development of a sustainable IoT society. The module’s compact design allows for easy installation, and it can also identify the internal status of electronic devices.
