A young Kenyan inventor might have developed a phone charger that can stand up to the pressure of daily use. Literally.
Researchers say “reverse electrowetting,” going on right in the sole of your shoe, could produce enough power to run a laptop computer.
A new integrated cellphone/kinetic charger concept spins on your finger to recharge battery and disassembles easily at the end of its life.
The Charge Battery concept by Yeon Kyeong Hwang & Mieong Ho Kang houses a kinetic charger and rechargeable battery in the same device, recharging via wind-up.
While many renewable energy technologies generate electricity via movement of the elements, a new class of devices are wholly human-powered.
The Cycle Wheel Harness concept by Jinsik Kim and Boseung Seo turns the wheel of a bike into a generator via kinetic energy, suitable for device charging.
A new concept design uses a nanogenerator attached directly to a shoe to harvest kinetic energy from everyday physical activities for powering mobile devices.
