Wireless data demands wireless power
The low power connectivity evolution has made it possible to create small devices that can transfer data wirelessly. But what if these devices could be powered without the use of batteries and the need to replace them? Imagine the value that reducing or eliminating batteries could bring to a world teeming with trillions of sensors.
This is exactly what Epishine has been imagining for years. Light is a fantastic way to transfer energy, and by optimizing our light energy harvesting modules, we harness indoor lighting to create energy to support these low power devices.
By using small supercapacitors your devices can stay powered even when the lights are off.
