Nowadays, many exoskeleton walking aids are perfectly functional in terms of functionality, but most of them still have two problems that cannot be overcome, namely, they are bulky and rely on batteries for propulsion. In response to the above shortcomings, a foreign biotechnology company has developed a lightweight walker without batteries. It relies purely on mechanical structure to help people with weak lower limbs, spinal cord injuries or stroke patients walk. They can walk freely without support. This walker is inspired by the tendon tissue of the horses leg. It uses a spring mechanism that fits the leg to absorb and release the energy generated during human movement to promote the entire walking process. The walker is already on sale in the United States. Before using the device, you need to obtain the guidance of a professional physician and customize the shoe device according to the users different conditions. This can improve the safety factor of the walker during use.
