the power of sound
With pioneering ultrasound technology, uBeam creates an aura of safe, wireless energy that charges your personal devices, keeping them all in perfect orbit. We are building the energy infrastructure of the future, helping us all cut the cords once and for all.
so how does
ubeam work?
transmitting
power

It all starts with the transmitter. It works like a speaker, but instead of emitting audible sound, it emits high frequency sound, which is inaudible to you and your pets.

ULTRASONIC SOUND THROUGH THE AIR

Humans can only hear sonic frequencies between 20 Hz and 20 kHz. uBeam emits sound far above the upper limit of human hearing, defined as ultrasound.

focusing
beam

uBeam emits targeted, focused power directly to receivers actively requesting power. When the requests stop, power delivery ceases.

RECEIVING
ENERGY

Like a microphone, the receiver picks up the sound and converts it into usable electrical energy using our proprietary energy-harvesting technology.

life at 100%
uBeam is an innovation that will breed innovation. Ubiquitous wireless power will lead to a world with smaller batteries and thinner, lighter devices. With wires virtually eliminated, TVs can sit in the middle of a room cord-free and light fixtures will become “stick-on” without the need for routed power. uBeam is also a universal standard, making those bulky travel adapters a thing of the past. Imagine charging your phone, laptop or even your hearing aid virtually anywhere, without any effort. This is life powered by uBeam.

the safety of sound.
Ultrasound has been used safely for nearly 100 years. It has been studied extensively due to its use in medical imaging, and, unlike X-rays, there is no issue with a cumulative effect, meaning there is no risk of prolonged exposure to the uBeam system. uBeam emits targeted, focused power directly to receivers that are actively requesting power, and power delivery ceases immediately once that request stops. Because uBeam’s system functions only in the “line of sight,” devices obscured by solid objects will not have power beamed to them. In the uBeam environment, you aren’t subjected to random acoustic power beams.
Completely safe, even when standing directly in front of the beam
uBeam’s ultrasound energy will not beam to the skin, and the power levels beamed are more than 50 times lower than the lowest ultrasound imaging exposure limits set by the FDA for medical imaging, making the system inherently safe and within all existing regulatory constraints.

Ultrasound is classified as “non-ionizing radiation,” meaning it does not have any of the properties of “ionizing radiation,” such as X-rays. Unlike ionizing radiation, ultrasound waves do not cause cancer, radiation sickness or other genetic damage. When transmitted through the air, uBeam cannot penetrate solid materials like skin. That’s very different from ionizing radiation like X-rays, UV rays, and Gamme Rays, which can cause free radicals leading to cellular radiation.

Unlike radio frequency emissions, ultrasound decays rapidly in the air. This creates a safe and containable system, ensuring that no power is sent beyond the set range of the transmitter. uBeam is the only wireless power technology that can be used in an aircraft, car or hospital because it does not interface with any existing communication systems or electronics.
ubeam's system is smart. real smart.
Meaning the ultrasound waves are only sent to and received by uBeam designated receivers (in this instance, the phone case that will be available at launch). Ultrasound can’t be emitted unless there is a uBeam receiver within range of the transmitter that is requesting power. If a person or other material comes between the uBeam transmitter and receiver, the system will stop emitting ultrasound.

Our system is set up such that humans and pets will not be exposed to the ultrasound, but we went a step further. If a person were to be exposed to the uBeam ultrasound source, 99.9% of the emitted ultrasound will bounce off the skin, which is the same occurrence as with fluorescent lights and rear parking sensors and other ultrasonic devices around us every day. Compare that with medical imaging, where the body absorbs most of the ultrasonic energy.
Pets, wildlife and ultrasound
uBeam operates at such a high frequency that even animals, such as dogs, are not sensitive to its transmission. Animals hear at different ranges, but uBeam’s frequency is too high for dogs and most mammals. Even if an animal could perceive the frequency of sound emitted by uBeam, the uBeam system power drops exponentially outside the narrowly-focused, emitted beams, making the sound effectively inaudible.
uBeam operates safely and complies with all regulatory bodies
uBeam has consulted with leading regulator legal authorities and determined that, beyond the standard regulatory issues consumer electronics require, we comply with the other current government regulatory requirements. The effect from uBeam on the human body is significantly below the FDA’s own limits.

Over the last two years, as part of the extensive due diligence of our investors, we have employed third party ultrasound and safety regulation experts to investigate the uBeam system for both performance and safety. They were fully satisfied that uBeam exceeds all safety and regulatory requirements.

Time is everything. That’s why we designed uBeam to keep charging your phone even while you’re moving, in any environment.
AT HOME

Smart phone meets smart home. Wireless power will revolutionize the way we organize and interact in our own space.

on the go

uBeam technology will soon be implemented in public transit systems, such as buses, trains and airlines, keeping us charged when we’re on-the-move.

AT work

With uBeam transmitters in the workplace, you can work freely in any space and move untethered throughout your day.

EVERY WHERE uBeam technology inside of coffee shops, gym, hotels and stadiums will make wireless power as pervasive as WiFi.
