Wonder what happened to UBeam, most recently "Sonicenergy".

Someone still owns ubeam I guess as it redirects to sonicenergy

Looks to me like a poor quality article/very vague (hardly any detail) with a stock looking photo.

I did look and it looks like it is real from an article I found from a reverse image lookup with the "stock looking photo" and see attached screenshot (translated)

- Using friction power generation, ultrasonic wireless energy transmission efficiency↑
- Expected to be used for wireless charging of batteries in underwater or human implantable electronic devices

The number of patients using implantable electronic devices such as artificial pacemakers and defibrillators is increasing worldwide due to advances in medical technology and an aging population . Currently, incisional surgery is required to replace the battery of implantable electronic devices, and complications may occur during this process . Accordingly, the need for a technology that wirelessly transmits power to the inside of the human body to charge the battery is emerging . Wireless power transfer technology is also required for devices that need to charge batteries in an underwater environment, such as sensors that diagnose the condition of submarine cables .

The Korea Institute of Science and Technology (KIST, President Seokjin Yoon ) announced that the research team led by Dr. Hyuncheol Song of the Electronic Materials Research Center has developed an ultrasonic wireless power transmission technology that can solve this problem .

Representative wireless power transmission technologies include electromagnetic induction and magnetic resonance . Electromagnetic induction is a technology already used in smartphones and wireless earphones, but it does not pass through conductors such as water or metal, and the charging distance is very short . In addition, there is a disadvantage that can harm the body due to heat problem during charging . In the magnetic resonance method, the resonant frequencies of the magnetic field generating device and the transmitting device must exactly match, so there is a risk of interference with wireless communication frequencies such as Wi-Fi or Bluetooth .

Instead of electromagnetic waves or magnetic fields, the researchers employed ultrasonic waves as an energy transmission medium . Sonar equipment using ultrasound is already common in the sea, and the stability of the human body has been guaranteed to the extent that ultrasound is commonly used in the medical world to diagnose organ or fetal conditions . However, the conventional energy transfer technology using ultrasound has low energy efficiency, making it difficult to commercialize .

The research team has developed a device that receives ultrasonic waves and converts them into electrical energy using the triboelectric power principle that can convert very small mechanical vibrations into electrical energy . By adding a ferroelectric material to the triboelectric generator, the research team greatly increased the conventional ultrasonic energy transmission efficiency of less than 1 % to more than 4% . Through this , it succeeded in charging more than 8mW of power at a distance of 6cm , which is enough to transmit data by turning on 200 LEDs at the same time or by operating a Bluetooth sensor under water . In addition, the device developed by the research team produced almost no heat due to its high energy conversion efficiency .

Dr. Song Hyeon-cheol said, “ In this study, it was shown that electronic devices can be driven by wireless power charging through ultrasound, so if the stability and efficiency of the device are further improved in the future, power will be wirelessly supplied to implantable sensors or deep-sea sensors, which are cumbersome to replace batteries. It is expected to be applied to technology that

The results of this research were carried out by the Ministry of Science and ICT ( Minister Hye -sook Lim ) , the Creative Convergence Research Project of the National Research Council for Science and Technology , the New R&D Project of the National Research Foundation, and the Energy Technology Development Project of the Ministry of Trade, Industry and Energy ( Minister Seung - wook Moon ) . The results were published in the latest issue of 'Energy & Environmental Science' (IF: 38.5, top 0.182% in JCR) , an international academic journal in the field of energy .
