YES! The new first battery mobile phone without charger crazes everyone which requires only 3.5 microwatts of juice. Power from radio signals and light help to transmit a signal back to the base station placed at a distance of 50 feet away. An antenna is attached to those components which transform in the standard analog radio signal. The process involves using almost no power.
The University of Washington scientists and electrical engineers have found a method in which analog signal converts into digital data so that sound gets transmitted easily without hindrance. The battery free cell phone is capable of utilizing the tiny vibrations which occur in a phone’s microphone or speaker while an individual is conversing.
Prof Shyam Gollakota, a researcher at University of Washington says, “We’ve built what we believe is the first functioning cell phone that consumes almost zero power.” “One could imagine in the future that all cell towers or Wi-Fi routers could come with their own base station technology embedded in it,” says Tall, a former UW electrical engineering doctoral student. “And if every house has a Wi-Fi router in it, one could get battery-free cell phone coverage ubiquitously.”
Author Vamsi Tall said the battery free mobile phone can be widely spread out due to its base station technology. To send speech, the phone uses vibrations from the device’s microphone to encode speech patterns in the reflected signals. While to receive speech, it converts encoded radio signals into sound vibrations that are received by the speaker. In the prototype device, the user presses a button to switch between these two “transmitting” and “listening” modes.
“In today’s world, we depend mostly on cell phones. Thereby, people will prioritize those devices which could sustain for long period of time without battery. More beneficial it will be if it were a cellphone,” says Joshua Smith, professor in both the Allen School and UW’s Department of Electrical Engineering.
We hope that rapid growth of technologies will merge the gap between imaginary perspective and the reality.
