The days of having to carry a phone charger everywhere could soon be igan researchers have revealed
a major breakthrough in harvesting energy from human say it could lead to smartphones powered for
a week by the motion of a swipe(重击).
Michigan State University’s low-cost device,known as a nanogenerator,has already been ntists successfully operated an LCD touch screen,a bank of 20 LED lights and a flexible keyboard,all with a simple touching or pressing motion and without the aid of a groundbreaking findings,published in the journal Nano Energy,suggest “We’re on the path toward wearable devices powered by human motion,” said Nelson Sepulveda,associate professor of electrical and computer engineering and lead researcher of the project.
“What I foresee,relatively soon,is the capability of not having to charge your cell phone for an entire week,for example,because that energy will be produced by your movement,”said Sepulveda,whose research is funded by the National Science Foundation.
Electrical energy is created when the device is compressed by human completed device is as thin as a sheet of device used to power the LED lights was palm-sized,while the device used to power the touch screen was as small as a ntages such as being lightweight,flexible and low-cost could make it a promising and alternative method in the field of Mechanical-energy harvesting.
The device also becomes more powerful when lveda said,“You can start with a large device,but when you fold it once,and again,and again,it’s much smaller and has more it may be small enough to put in a specially made heel of your shoe so it creates power each time your heel strikes the ground.”
Sepulveda and his team are also developing technology that would transmit the power generated by the heel strike to,say,a wireless headset.
