Chinese researchers published a paper in the new issue of the American Journal of Applied Physics, saying that they have developed a power generation device that can be worn on the legs. It can generate electricity by capturing the kinetic energy generated by the knee bending when people walk. Wear a health monitor and other power supplies. Professor Liao Weixin of the Department of Mechanical and Automation Engineering, The Chinese University of Hong Kong, China and his team used piezoelectric fiber materials and connecting rods to design a device with a similar engine crank structure. The device weighs only 307 grams.
After being worn on the legs, it can capture the kinetic energy generated by the knee's natural bending while the human body is walking, and convert it into electrical energy.
When a person wearing this device walks at a speed of 4 kilometers per hour, the output power of the device is 1.6 microwatts. The researchers compared the breathing conditions of the subjects when they walked with and without the device, and believed that walking with the device did not require extra effort.
Previously, some wearable energy harvesting devices used vibration generated when people walked to generate electricity, with low efficiency. Liao Weixin said that people ’s walking frequency is very slow, and the efficiency of collecting energy from vibration is low, and the equipment developed this time uses the kinetic energy generated by knee bending to bypass this limitation.
Researchers believe that the new human kinetic energy collection technology is expected to promote the development of wearable devices, so that wearable health monitors and other "self-powered", users can get rid of the inconvenience caused by the need to charge frequently.
