A group of researchers at the Hong Kong University of China recently developed a technology that can operate your devices by walking.
The researchers explained that the energy in the knee can generate 1.6 microwatts of power, and this energy is sufficient to operate health monitoring devices and GPS devices.
According to the author Wei Hsin Liao, a professor in the Department of Mechanical Engineering: “Self-operating GPS devices will attract the attention of the mountaineer.
The scientists used the smart microbe, which generates energy by any kind of bending, to create a mechanism, similar to what drives the engine, so they attach the device to the knee because of the large movement of the knee joint compared to most other human joints,
Thanks to the bends that occur when wearing this material, every time the knee is flexed, the device bends and generates electricity. This means that the bio-mechanical energy can be obtained through the normal movement of the human knee.
The first model weighs only 307 grams (0.68 pounds) and has been tested on people walking at speeds of 2 to 6.5 kilometers per hour (about 1 to 4 miles per hour).
Researchers compared breathing patterns worn to and without the device, and determined that the energy needed for walking did not change , Which means that the device generates energy at no cost to the human.
