Internet of Things


Smart applications need smart energy

Globally networked devices, machines and sensors have long left the realms of fantasy and become reality thanks to the “Internet of Things” (IoT). The Internet of Things is about to revolutionise our daily lives. A precisely tailored energy supply is an essential prerequisite for ensuring that the growing and increasingly differentiated IoT applications function. We are focusing on the technologies Lithium-Ion, Lithium and Nickel-Metal Hydride cells as tailor-made energy supply for the diverse applications in the IoT.


A customized primary lithium coin cell LIR2032 with pin tags empowers for example the world´s smallest wireless sensor. These IoT sensors are tiny, robust, low cost and scalable with a long battery lifetime.
