Energy harvesting and solar charging ICs from ST supply the Internet of Things ecosystem by extracting energy from ambient light or thermal differences to power small devices in applications such as wireless sensors for smart lighting, home and building automation, remote monitoring, presence detection and industrial equipment controls as well as wearables and fitness sensors.

These ICs make the small devices energy autonomous and protect the environment by reducing the use – and waste – of primary batteries, while reducing the heavy impact of cabling cost and enhancing flexibility in legacy buildings. Given their ability to “cut the cord” and replace primary batteries, hundreds of millions of these devices could be deployed in environments such as offices, buildings, hotels, industrial sites, airports, malls, remote monitoring infrastructures and wearable fitness / healthcare devices.



eDesignSuite is a comprehensive set of easy-to-use design-aid utilities ready to help you streamline the system development process with a wide range of ST products.
