GenerEn develops patent-protected magnetic-flux and vibrational energy harvesters that power battery-free wireless transmitters and remote-control systems. Led by inventor David Deak, the St. James, New York company also makes a batteryless water-leak detection system designed to trigger wireless alarms and shut off water supplies. Its generators are offered through licence-to-manufacture agreements and are compatible with EnOcean and Ezuria transmitter modules.
GemnsGemns, the new name for WePower Technologies, develops patented electromagnetic energy-harvesting generators that turn everyday motion into battery-free power for connected devices. Its technology began with industrial wireless switches and now supports applications such as smart-home controls, lighting and remote sensors, delivering up to 40 times the output of earlier kinetic harvesters. Led by founder and CEO Larry Richenstein, Gemns holds more than 15 patents across multiple countries.SAGAPONACK, NY
