A study shows that the gastrocnemius muscle group on our calves has a special function, which is to buffer the kinetic energy generated during walking. Some scientists in the United States have taken advantage of this feature to develop a walking exoskeleton device, which is tied to the heel and calf knee. When we walk, the springs behind it will absorb/release the kinetic energy generated, and when the soles of the feet push on the ground, they will be cushioned. The kinetic energy of the spring will be released to help the soles of the feet to exert force. This cycle helps us walk more easily. According to reports, wearing this exoskeleton is equivalent to losing 4.5 kilograms of weight.
