During the walking process, the human body spends little energy, but, according to some researchers at the University of Michigan, in the United States, little energy can be collected and converted into electricity. For this purpose a special device is being developed that, grasped at the knee, collects the energy generated in the walking process. Researchers have shown that electricity can be obtained efficiently by studying knee

movement. When walking, when the knee advances in each step, it takes speed. When the foot touches the ground, the knee stops in the new position on the foot. The energy the device receives is the braking energy of the knee. Due to the weight of the device, the occupant must perform an additional force to dress the device, but researchers have managed to capture more energy than this, enough energy to launch a mobile phone or a GPS, according to them.
