The Powermat PMT 100 is a wireless charging solution that allows small IoT devices to be charged more safely at faster speeds. The Powermat PMT 100 is a hybrid solution that uses both inductive wireless charging and resonance, thus, creating more power, more freedom of positioning, longer ranges between wireless power transmitters and receivers , and low implementation costs. In addition, the module does not require any external receiver, microcontroller and few peripheral components, thus reducing the complexity of the design and cost while also reducing the size of the product. The Powermat PMT 100 enables a higher level of performance and a seamless charging user experience at a price that supports the scale. The PMT 100 is suitable for use in a variety of applications including small medical, lifestyle, and smart home internet of things (IoT) devices.

“IoT unlocks enormous business value and stands to change many aspects of our society,” said Powermat CEO Elad Dubzinski. “Whether in the form of small personal health trackers that detect exposure to COVID or home security systems, these devices need reliable wireless power and seamless connectivity to unlock their full potential. -function – where the Powermat is.”

The PMT 100 takes advantage of Powermat’s SmartInductive Technology, which is based on magnetic induction but allows a wider range of capabilities than traditional magnetic induction solutions found on the market today. It offers a hybrid solution between inductive wireless charging and resonance, producing more power, more positioning freedom, longer ranges between wireless power transmitters and receivers, and lower implementation costs.
