AirCord™ Technology
Far-field wireless technology that has power, distance, and safety.
At Wi-Charge, we are making Nikola Tesla's dream of far-field wireless power transmissions a reality. While Tesla dreamed of beaming energy via large conductive coils, we found a more practical, efficient, and safer means of over-the-air power transmissions by using infrared beams. With more than 8 years of deep R&D, we've figured out how to harness the power of infrared to beam several watts of power at distances of 30 feet or more to thumb-sized receivers that can be embedded in all types of IoTs and other electronic devices. Furthermore, Wi-Charge transmitters support charging of multiple receivers, smartly dividing the total energy among charged devices.
Power
AirCord™ delivers more usable power over distance than any other approach, enough to safely charge even a smartphone. This is thanks to a focused beam that transfers the energy directly from the transmitter to the receiver.
Distance
AirCord™ powers devices at room-sized distances and beyond. Power is the same regardless of distance, unlike other technologies whose power drops as a function of the distance squared.
Safety
AirCord™ is certified safe for consumers in all usage scenarios. Power is delivered only to the target device and does not bathe the environment with unwanted radiation.
AirCord in action
The demo video above demonstrates what the future of power looks like. For our partners, this future is present reality. Each Lego train in the video represents an electronic device that can be powered wirelessly, whether static or in motion.
​
It can be your smartphone or electric toothbrush at home, a digital display at the edge of a supermarket shelf, a vibration sensor on an industrial production floor, or a smart door lock in a hotel hallway. It can be anywhere you need to power devices at a distance, over the air, safely, and without user intervention.
How it works
Wireless Power Transmitter
​
-
Plugged to the mains (AC or DC) or track lighting
-
Converts electricity into safe infrared beams
-
Automatically identifies client devices
-
Delivers infrared energy to client devices
Wireless Power Receiver
​
-
Plugged to or embedded in a client device
-
Receiver converts IR to electricity
-
Receiver charges an internal rechargeable battery or a super-capacitor which the client device uses
-
The receiver sends back client device telemetry including battery status, usage stats, billing info etc.
