Wi-Charge systems deliver power using narrow beams of infrared light.
The Wi-Charge transmitter (often mounted on the ceiling) sends focused and safe infrared beams to receivers. Receivers (typically embedded in the devices to be powered), convert the light to electricity. Receivers use small photovoltaic cells. This concept is similar to solar panels converting sunlight into electricity.
Infrared beams can travel with little degradation over a distance. Thus, Wi-Charge systems can efficiently provide power across a room.
Not yet, but soon.
We are working with select partners to integrate our technology into unique products. Are you excited about the breakthrough opportunities that wireless power transmission brings? Do you want to invest with us in bringing this to market? If so, let’s talk.
There are other ways to transmit power wirelessly. For instance, others have used RF, ultrasound and magnetic approaches.
The best approach depends on the specific application. Having said that, we feel that our infrared technology is dramatically better in being able to safely and efficiently deliver high power (watts) over a long distance (meters).
When looking at an alternative approach, ask yourself questions such as:
We put together a white paper comparing the various technologies. Contact us to request it.
We have publicly demonstrated power delivery of approximately 2.5 watts over 5 meters (~16 feet).
We are working on delivering more power over greater distances.
Qi pads charge phones that touch or are very close to the Qi charger, which is near-field charging technology. However, Wi-Charge technology can charge phones from afar, such as from across a room. It is a long-range power technology.
With Wi-Charge, the device to be charged can be anywhere in the room and does not have to be placed on the charging pad.
Just like phones, Wi-Charge can also power wireless speakers and other devices that cannot be practically placed on a charging pad.
Both US and international regulatory agencies have reviewed and approved Wi-Charge products and determined them to be safe.
The green areas on the map below designate countries for which Wi-Charge already received safety certification. Contact us for details or any questions.
Our products classify as Class 1 laser products, which is the category of products that are (safe under all conditions of use and exempt from any protective measures.
Our products use infra-red light which is a natural light used in other devices such as remote controls. IR accounts for 50% of sunlight and has always been part of Earth’s ecosystem.
