59-year-old Les Baugh lost his both arms as a teenager. Now he is testing a new generation of prosthetic limbs. These limbs absorb the signals given from the brain to the external body regions for an action and send the right signal to the artificial arm, for eg. close the fingers. This technology still need some years to become ready for the mass production. Especially because it’s very expensive. The price is at 500.000$ per arm.
