Nowadays smartphones are coming with different brands and a lots of features but the most competitive part is keeping the smartphone charged.  It is the biggest issue when you are traveling.

But due to rapid development in the technology, charging the smartphone with just a finger swipe may be soon be possible. It is due to a new low cost, film like device that can harvest energy from human motion. This device is known as nanogenerator.

Scientists 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 they have used it without the aid of any of a battery.

“We are on the path towards wearable device powered by human motion”, said Nelson Sepulveda, associate professor at Michigan State University in the US.

“What I foresee, relatively soon, is the capability of not having to charge your cellphone for an entire week, for example because that energy will be produced by your movement,” said Sepulveda.

This device is as thin as a sheet of paper and can be adapted to many applications and sizes.

The innovative process starts with a silicon wafer, which is then fabricated with several layers or thin sheets of environmentally friendly substances including silver, polyimide and polypropylene Ferro electret.

Ions are added to the device which keeps the device particle charged. When the human motion is created, an electrical energy is created by the motion compression or mechanical energy.

This completed device is called a bio-compatible Ferro electret Nanogenerator or FENG.

Remarkably, the device also becomes more powerful when folded.

“Each time you fold it you are increasing exponentially the amount of voltage you are creating”, Sepulveda said.

“You can start with a large device, but when you fold it once, and again and again, it’s now much smaller and has more energy”, he said.

“Now 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”, he said.

Researchers and scientists are developing the technology that would transmit the power generated form the heel strike to say, a wireless headset.

There are a lots of advantages of this device when developed and come to the use in the public. It’s lightweight, flexible, bio-compatible, scalable, low cost and robust which could make FENG “a promising and alternative method in the field of mechanical energy harvesting”, for many autonomous electronics such as wireless headsets, cell phones and other touch screen devices according to the study.

This will utilize the touch screen advantage which is broadly getting used nowadays.
