The Gemns G100 EHG Wireless Panel Switch by WePower Brings Energy Harvesting to IoT Product Design and Development

The G100 EHG replaces a traditional battery to harvest kinetic energy as the power source for wireless signal communications.

Sagaponack, NY – May 17, 2023 – WePower Technologies, a provider of  patented energy harvesting solutions for wireless data transmission in IoT  and IIoT devices, has released the Gemns™ G100 EHG (G100) Wireless Panel  Switch for OEMs and product developers. The G100 is part of the portfolio of  WePower patented technologies that enable reliable and lifetime  maintenance-free performance in large-scale deployment of IoT devices for  industrial, automotive, smart home, smart city, and aerospace applications  that are simply not achievable with device designs dependent on battery  power. 

What is the G100? 

The G100 is an EHG in a Wireless Panel Switch form factor for industrial  applications. The G100 uses both stationary and oscillating magnets to  harvest kinetic energy through electromagnetic induction. In the reference  design pictured below, the G100 is realized in a standard 22mm panel mount  switch that contains both the EHC100 (Gemns energy harvester charger  board) and the manufacturer’s chosen MCU or RF transceiver board as the  target application. With the simple activation of the G100’s push button, over  3 millijoules of usable energy are available to power a target’s MCU and  perform such tasks as reading sensors, performing computations, and  transmitting encrypted data over an RF link. The energy produced transports  signals such as BLE, Zigbee Green Power Device, LoRa, Z-Wave, Thread, and  other wireless communications easily, with up to 20-dBm of output power. The G100 is retrofittable into the common push button of today’s industrial  machinery controls with no new design engineering. 

“The future of IoT is pervasive connectivity. It’s where everything is connected  and exchanging data wirelessly over trillions of sensors. But this connectivity  comes at a price; more wireless sensors mean more batteries, and more  batteries mean more waste and downtime,” said Larry Richenstein, co founder and CEO of WePower Technologies. “WePower has engineered a technological solution that is now ready for integration in millions of IoT  devices.” 

Benefits to Manufacturing 

The future requires autonomously powered, maintenance-free, and  permanent wireless solutions. Harvesting energy from motion for on-demand power is a sustainable way to eliminate the need for battery power in many  product designs, thereby reducing the costs associated with integration,  recurring maintenance, wiring, and waste. On-demand energy also means  less downtime and less manpower needed to manually replace batteries  across complex infrastructures. WePower is helping manufacturers rethink  how sensors both in the IoT and IIoT are designed for environmentally green,  maintenance-free, ultra-reliable operation. 

Anticipated applications include remote on/off control of devices and  equipment, wireless door sensors, industrial on/off switches, and remote  triggering controls. The core G100 energy harvester mechanism also lends to  easy design and integration into custom solutions and applications.  

Case Use Example 

Wireless remote controls are used in industrial and automation applications  to control such devices as pumps, valves, lighting, cranes, and motors.  Consider an industrial application operated by a wireless remote control. 

In this example, this remote switch houses a cell battery and  transmitter to send the signal to remotely turn on an industrial water pump located approximately 1 km away.  With daily use in an industrial setting, the life expectancy of  this battery is under 3 years.  Using the G100 to replace the current design, the device  will no longer need a battery, and instead, harvests kinetic  energy from the push button motion to provide an ultra  reliable, maintenance-free solution.

In a replacement design, the G100 will harvest energy from the 70 ozf  actuation force to produce upwards of 3 millijoules of energy depending on  the application load profile. Load-dependent energy output curves are provided below for reference.
