September 16, it is reported that American researchers have made full use of human kinetic energy to develop a device for generating electricity by using human motion, put them in shoes, and generate electricity while walking. They can charge mobile phones, MP3 and other devices.

Crew Pepin and Taylor, Professor of mechanical engineering, University of Wisconsin, published a report in the magazine to reveal the details of the device.

Crew Pepin said: "in general, a person is a machine that can generate powerful energy. When fast running, a person can generate 1000 watts of power."

He explained that in the past, researchers had tried to pform kinetic energy into electric energy while walking, but the efficiency was too low to be of practical value.

He and his colleagues invented a new energy harvesting technology: reverse electrowetting, which can solve this problem.

Electrowetting is the use of voltage to change the shape of droplets on the hydrophobic surface. In turn, the researchers used this principle to pform the energy of micro droplet flow into electrical energy.

The device is similar to a shoe insole, containing thousands of tiny droplets.

Inside, with the power generated by walking, the power can reach up to 10 watts.

According to the researchers, enough to charge a cell phone or laptop.

Charging through human motion has been used in some devices that consume less energy, including watches and sensors.

There has been no high energy consumption device for mobile phones.

How to connect power generation devices to mobile phones is still a challenge.

One way is to insert a USB wire on the shoe, but this method may not be very practical.

Scientists at University of Wisconsin have put forward a more ingenious way to connect the power generation devices and the most electric part of the cell phone to the shoes, and then connect the device to the mobile phone in a short-range wireless pmission system, such as Bluetooth.

The soldier's shoes are equipped with this.

Soldiers can take fewer batteries and reduce weight.

At the present stage, some soldiers in the United States are carrying 9 kilograms of equipment on their backs so that they can recharge the night vision goggles and electronic devices such as the global positioning system.

Japan's two railway station laid electric blankets and went over to generate electricity.

In fact, it is a precedent to use the human body to generate electricity.

The two railway stations in Tokyo, Japan, are laying electric blankets under the floor, using the vibration generated by pedestrians when they walk to generate electricity on the ground, generating electricity to provide automatic doors for railway stations and other equipment.
