WePower introduced itself to me (and the world) at CES 2023. Way back when process instrumentation companies were developing wireless sensors (remember the “wireless wars”?) the big question was battery life. I was just searching for the first energy harvesting company I interviewed. I guess it was published at Automation World rather than my blog.
Technology progresses. WePower unveiled some cool energy harvesting generator (EHG) tech last year. They are back at CES this year with three additional products.
Wireless, batteryless Gemns EHGs from WePower harvest energy from motion and convert it into usable electricity for small-scale data transmission devices like sensors across a wide range of applications. This waste-free transient power generation is critical to the growth of the IoT, especially in the United States where consumers throw away more than three billion batteries a year.
- G100 Push-Button Switch: This 22mm push-button switch uses permanent and oscillating magnets to capture kinetic energy at a rate of more than 30 times that of the competition, and convert it to usable electricity, enabling a transmission output exceeding 8 dBm. This extra power enables data transmissions of significantly larger size, complexity, and distance across most advanced communication protocols, including ISM, Bluetooth, LoRa, Z-Wave, Thread, and Matter. The G100 push-button has been tested for a lifespan of over one million activations and is ideal for applications in industrial settings, smart home, and smart building environments.
- G150 Vibration-Activated EHG: This continuous operation EHG component draws power from vibrations to drive its functionality as a sensor. WePower will demo this component using a speaker with variable vibration to showcase the product’s ability to harvest energy continuously while also registering and communicating the vibrations’ magnitudes. This combination of functionalities make the G150 EHG an ideal solution for applications in the mining and automotive industries where any variation in production line performance must be caught and communicated.
- Industrial Limit Switch with G200: Designed to integrate seamlessly with industrial limit switches, the G200 EHG powers secure wireless transmissions across a diverse range of chips and is compatible with most advanced communication protocols. The principal unique benefit of the G200 is its substantially higher power output compared to current market offerings, enabling a game-changing two-way communication in industrial settings. This capability allows networks to confirm the receipt of safety-critical transmissions, ensuring that vital communications are both uninterrupted and verified, wirelessly and without the need for batteries—ultimately streamlining operations, reducing risk, and cutting down on waste.
