While smartphones, smart homes, and even smart wearables are growing more advanced, they are still limited by power. The battery hasn’t advanced in decades. But we are on the verge of a power revolution, the future of batteries looks bright.
It may be some time before we get a week’s battery life from our phones, but development along those lines is progressing well. While chips and operating systems are becoming more efficient to save power we are still only looking at a day or two of use on a smartphone before having to recharge. From super-fast 30-second re-charge, the future of batteries will also include ‘over the air’ charging on gadgets soon.
uBeam ‘Over the Air’ Charging.
uBeam uses ultrasound to transmit electricity. Power is turned into sound waves, inaudible to humans and animals, which are transmitted and then converted to power upon reaching the device. The uBeam concept was stumbled upon by 25-year-old astrobiology graduate, Meredith Perry. She started the company that will make it possible to charge gadgets over the air using a 5mm thick plate. These transmitters can be attached to walls, or made into decorative art, to beam power to smartphones and laptops. The gadgets just need a thin receiver in order to receive the charge. This is considered the future in the world of gadgets.
StoreDot charges mobiles in 30 seconds.
StoreDot, a start-up born from the nanotechnology department at Tel Aviv University, has developed the StoreDot charger. It works with current smartphones like Samsung Galaxy series and iphone 11. The result is a charger that can recharge smartphones in 60 seconds and 10 minutes maximum. The battery comprises “non-flammable organic compounds encased in a multi- layer safety-protection structure that prevents over-voltage and heating”, so there should be no issues with it exploding. The company has also revealed plans to build a battery for electric vehicles that charges in five minutes and offers a range of 300 miles.
