There are many 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.
SonicEnergy, a specialist inventor of ultrasonic power-at-a-distance Always-On Wireless Energy utilizing ultrasafe, ultrasonic array technology, delivers reliable, long-range wire-free charging. The innovative wireless technology uses ultrasonic transducer arrays to convert electrical energy into acoustic energy. It transmits this energy through the air in a tightly focused beam, to power electronics tens of feet away.
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, SonicEnergy’s system will automatically stop.
Since it’s a contained system, SonicEnergy 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.
Like a microphone, the receiver picks up the ultrasound waves and converts the acoustic energy back into usable electrical energy via SonicEnergy’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.
SonicEnergy’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.
By developing proprietary transducers, transmitters, receivers, and custom enterprise software, SonicEnergy’s technology delivers usable power to devices ranging from portable electronics, medical & aerospace devices, to IoT devices and networks. As the technology is safe and non-invasive, it is not limited by FCC power regulations. This allows SonicEnergy to achieve higher power density.
