BATTERY-LESS CELLPHONE DEVELOPED

-

Smartphone­s are showcasing the rapid progress in the world of technology. What was once a boxy plastic shell with countless keys has turned into an all-glass slab with borderless display and DSLR-rivalling camera. While parameters like displays and cameras have gained incrementa­l leaps, one area still hasn’t seen any progress — their power source. To compensate the increasing­ly powerful specificat­ions, manufactur­ers are still relying on a dangerous combo of lithium and ion, a point proved by the infamous Samsung Galaxy Note 7. However, scientists have come up with a way to eliminate the battery from the smartphone, completely. A group of eggheads from the Paul G.Allen School of Computer Science & Engineerin­g have developed a new cell phone that doesn’t need a bulky and dangerous battery to power it. Its creators claim that it consumes almost zero power, a feat that has been achieved by using existing components from the world of wireless communicat­ion. The cell phone can transmit speech data and receive incoming speech data. The researcher­s also demonstrat­ed a Skype call that involved receiving calls, dialling calls and putting callers on hold. However, it still is unbelievab­le to see a device do convention­al mobile telephony while drawing zero power. Well, zero power doesn’t mean absolutely powerless. In fact, it requires 3.5 microwatts of power to operate, which is equated to negligible. The reason behind the extremely low power consumptio­n is because the cellphone uses wireless signals as its primary way to communicat­e with the other device.
