Take action to power devices sustainably, battery-free.
Discover Gemns™ Energy Harvesting Technology for Modern Device Design
“In the trillion IoT sensor world predicted for 2025, we are going to be throwing over 100 million batteries everyday into landfills unless we significantly extend battery life”
Mike Hayes, head of ICT for energy efficiency at the Tyndall National Institute in Ireland.
The Future of Power
For decades, batteries have powered the connected world, but they’ve also held it back. Every wireless sensor and switch eventually needs replacement power, leading to maintenance headaches, design limitations, and billions of batteries being discarded each year.
Gemns™ energy harvesting technology changes that.
Using an existing motion, such as a push, flip, or press, Gemns captures and converts kinetic energy into clean electrical energy that powers wireless transmissions instantly. Each energy harvesting generator is battery-free, maintenance-free, and infinitely repeatable.
Gemns represents the next generation of energy harvesting generators, engineered to deliver up to 40× more energy output than comparable generators and power the future of sustainable IoT design.
Why It Matters
Gemns™ Energy Harvesting Technology
The growth of the Internet of Things has created a new challenge: how to power billions of remote sensors and devices reliably, efficiently, and sustainably. The world needs autonomous, maintenance-free energy, and Gemns delivers it.
Our patented electromagnetic induction technology harvests energy at a significantly higher voltage level than any other kinetic energy harvester on the market. This enables the transmission of higher-quality RF signals over longer ranges, with compatibility across today’s most common wireless standards, including Bluetooth, LoRa, Z-Wave, Matter, Thread, and ISM.
Gemns eliminates the cost, complexity, and environmental impact of batteries, unlocking true freedom in device design

Powering the IoT: Gemns™ Energy Harvesting Generator (EHG)
-
Permanent Magnets
Gemns devices utilize precision-engineered permanent magnets for optimal field shaping and concentration, resulting in a higher energy output through electromagnetic induction. This enables greater functionality, reliability, and transmission range from sensors and switches.
-
No Batteries Required
Gemns energy harvesting generators are designed directly into IoT devices to permanently eliminate the need for batteries. They’re small, durable, and endlessly repeatable, reducing maintenance while increasing performance, whether powering a million-sensor network or a single smart switch.
-
40 Times More Power
Gemns energy harvesting generators deliver energy in the millijoule range, which is 40 times greater than that of competitive kinetic energy harvesting generators. More power means longer RF range, higher data integrity, and expanded processing at the edge.
-
Protocol Agnostic
Gemns products communicate seamlessly via Bluetooth, LoRa, ISM, Z-Wave, Matter, and Thread. Designs can be adapted to meet your requirements for form factor, energy demand, and environmental rating.
