No sooner had interest in wireless sensors developed batteries were identified as a weak point. Sending maintenance crews out routinely to replace batteries became a sticking point. For every difficulty lies an opportunity. Technologies to harvest energy from equipment vibrations and other sources went into development.
Here we are many years later and a notice of more kinetic energy harvesting came my way thanks to an exhibit at the annual Consumer Electronics Show in January.
WePower Technologies introduced Gemns Energy Harvesting Generator (EHG) product line. The Gemns product line includes three distinct products, each of which use both permanent and oscillating magnets to harvest kinetic energy through electromagnetic induction: the Gemns G100 Integrated RF Switch, the Gemns G200 EHG, and the Gemns G300 EHG.
The kinetic energy transient provided by each of these Gemns products can be used to trigger a sensor, perform a reading, form a data packet, and transmit a radio signal with the range and reliability necessary to advance the RF communication needs of the IoT industry.
The three products are:
- Gemns G100 Integrated RF Switch – A wireless industrial push button, the G100 has been tested to over 1 million activations and has served as the initial proof of concept for the growing Gemns product lineup. The G100 includes space for Gemns’ energy harvesting circuit and another PCB that would typically be the transmitter. Anticipated applications beyond industrial will include automotive, smart home and city, and aerospace.
- Gemns G200 EHG – The workhorse of the Gemns lineup, this is our most powerful EHG. Initially designed for industrial IoT applications in safety and limit switches, the expected applications where the G200 will excel include automotive, home/office IoT, and other higher energy applications.
- Gemns G300 EHG – A high-output device that requires less force to activate, making it useful for consumer products in lighting and smart home devices, as well as in future IoT products where new activation methods will be explored.
