Abstract
Abstract Due to various causes such as diseases, natural calamities, accidents, and other miss-happening, hundreds of thousands of people have lost limbs, notably the lower half of the body. According to a survey conducted in India, in 2011 out of 121 crore population, about 2.68 crore persons are physically disabled which is approximately 2.21487% of the total population of India. Human tissue cannot be regenerated using the current biomedical technology. The most optimal way to compensate for the ambulation of amputated lower limbs is a prosthesis. The smart prosthesis orchestrates electronic technology, biomedical technology, mechanical technology, control technology. It incorporates a shank pole, thigh pole and a prosthetic foot, and the connection between the human body and the lower limb prosthesis. The knee joint has one degree of movement and is controlled by resistance spring. The smart prosthesis leg's foot and ankle joint has one degree of freedom of movement and adopts energy-storing solid ankle prosthesis. The mechanism can mimic the natural movement of a leg, thereby helping amputees gain mobility and freedom to move. This reflects progress socially and elevates awareness and compassion to relieve an amputees’ pain. Essentially, the amount of care required for the disabled is scaled down.
