How uBeam Works
uBeam’s innovative wireless technology uses ultrasonic transducer arrays to convert electrical energy into acoustic energy.
Then it transmits this energy through the air in a tightly focused beam, to power electronics tens of feet away. uBeam is a safe and reliable wireless energy solution that can make the vision of an always on IoT network a reality.
The transmitter works like a regular audio speaker, except it transmits an ultra-high frequency sound that is imperceptible to the human ear. The transmitter is modular and can be scaled to an appropriate size for any application. Each transmitter can be customized to include functionalities such as dynamic beam forming, computer vision, mobile receiver tracking, and simultaneous multi-receiver support.
Like a microphone, the receiver picks up the ultrasound waves and converts the acoustic energy back into usable electrical energy via uBeam’s proprietary ultrasonic transducers. The receivers can be charged either while they’re static or in motion. The receivers can be embedded directly into various electronic devices, or as retrofit kits to replace existing batteries or cords.
uBeam’s proprietary power management software allows users to monitor devices on a real time basis, and obtain insights on power levels, device health, sensor readings, and more. The information is stored securely on Amazon Web Services (AWS) and historical data can be used to analyze trends and predict future performance.
Safe and Reliable Wireless Power Solution
Safer. Smarter. Higher Power.
The Safety of Sound
Ultrasound is inherently safe and has been used in various applications for more than 50 years – from parking sensors to cleaning equipment. Unlike radio frequency emissions, ultrasound does not permeate surfaces or walls. If a person or an object is in between the transmitter and the receiver, uBeam’s system will automatically stop.
Since it’s a contained system, uBeam will not transmit acoustic energy outside its predefined beam. It’s the only wireless energy technology that’s safe for use in aircraft, cars, or hospitals, because it doesn’t generate any electromagnetic interference that could compromise the performance of other electronic devices.
Higher Density Power at a Distance
Because uBeam’s technology is safe and non-invasive, it’s not limited by FCC power regulations. This allows uBeam to achieve higher power density. We believe this will propel uBeam into the leadership position for power transfer at a distance.
uBeam vs Other Technologies
There are several other ways to transfer electrical power wirelessly – induction, magnetic resonance, RF and infrared lasers – all of which are electromagnetic. Issues with using electromagnetic energy to transfer power include interference, tissue penetration, material heating and strict FCC/FDA regulations capping power outputs.
uBeam has done extensive due diligence to ensure the safety of our ultrasound technology. We’ve studied decades worth of research. We’ve employed some of the best third party ultrasound and safety experts as well as top tier universities to ensure the entire system performs safely. All of our findings over the last 24 months indicate that uBeam causes no adverse effects.
