Scientists Develop A Phone That Can Make Calls Without A Battery
"One of the biggest gripes consumers have with their smartphones is the battery life. While we have seen big leaps in almost all aspects of a modern smartphone, the battery technology has remained stagnant.'' That problem may be one step closer to being solved, though. In the future, phones may work without a battery. Scientists at the University of Washington have created a mobile phone prototype that doesn’t require a battery to operate. The phone consumes almost zero power and runs by obtaining energy from ambient radio signals or light. The research team demonstrated the prototype using Skype, and they were able to receive incoming calls, dial out numbers and place callers on hold with the battery-free phone. Though the battery-free phone still requires a small amount of energy to perform certain operations. The prototype has a power budget of 3.5 microwatts. The power is obtained from ambient light with a very small solar cell which is roughl...
