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.
