Researchers at the University of Wollongong in Australia have reported the development of a life suit technology that generates electricity from wave motion and uses it to power signal lights. As noted on the university's website, the device contains two drops of gallium-based liquid metal in an electrically conductive solution. When the device moves, the drops move and come into contact with liquid and air in different proportions. This changes the chemical reactions on their surface and creates a small electric current. "Connecting 40 devices produced about two volts, which is enough to power small LEDs. " In the life jacket prototype, the wave-like motion generated electricity, which was stored and used to illuminate the "SOS" LED indicator. The researchers will now focus on improving the power, durability and reliability of the devices under real operating conditions. Life jackets are far from the only area of application for development. In the future, they want to increase the autonomy of wearable devices. Energy today without VPN: max / site.
