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

Aerospace

In air and space travel, every gram and wire matters. Gemns supports lighter, more flexible control layouts and helps manufacturers reduce wiring complexity and power load.

Lighting Control

The Gemns G300 EHG makes wireless, battery-free lighting a reality by replacing wired switches with self-powered controls that can be mounted anywhere, with no maintenance required.

Smart Homes & Buildings

Gemns enables next-generation smart devices, self-powered door sensors, leak detectors, lighting switches, and remote controls, without wires or batteries. Place controls anywhere, not just where the wiring allows.

Automotive

Lightweight and simplified wiring are priorities in modern vehicles. Gemns enables wireless switches and sensors without adding weight, wiring, or maintenance needs.

Energy & Utilities

Remote power generation sites are costly to instrument and monitor. Gemns provides reliable, self-powered sensors for wind, solar, and hydro applications, reducing wiring costs and improving data transmission reliability.

Industrial & Manufacturing


Gemns began here. Originally designed to replace wired limit and safety switches, Gemns powers robust wireless industrial networks. With the G100 and G200 EHGs, facilities can deploy batteryless sensors and emergency switches across large operations.

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.
