What if instead of electricity used ultrasonic waves to upload your mobile phone or computer? Wireless energy may be about to reach markets.
An investigation team led by Sunghoon Hur has developed a device that resolves many of the deficiencies of current technologies Wireless energy transmission.
The authors of this week in Advanced Materials created a extensible and biocompatible ultrasonic receiver which fits perfectly to the curves of the human body, gaining simultaneously a stable energy conversion.
According to scientists, ultrasounds are more “friends” of tissues and less absorbed by the body. Thus, they become a reliable option for feeding implantable devices adherent to the skin.
The device was created through the use of Piezoelectric subjects of high efficiency and a unique structural conception.
They were able to transmit 20 MW of power at a distance of 3 cm from underwater and 7 MW at a depth of 3 cm from the skin. This power is sufficient to continually feed low power portable devices or implantable medical devices.
It is now expected that the device can be applied not only to medical devices, but also the drones underwater and sensors Marine that need long -term electric power, explains the.
“Through this investigation, we have shown that the transmission technology of wireless energy Using ultrasounds can be applied to practice, ”said Sunghoon Hur.“ We plan to conduct more research to miniaturize and marketing to accelerate the practical application of technology. ”
