The HAL (Hybrid Assistive Limb) suit works by detecting faint bio-electrical signals using pads placed on specific areas of the body. The pads move the HAL suit accordingly and can increase user strength by up to 10 times.
When a person attempts to move, nerve signals are sent from the brain to the muscles via motoneuron, consequently moving the musculoskeletal system as the result. At this moment, very weak biosignals can be detected on the surface of the skin. HAL catches these signals through a sensor attached on the skin of the wearer. Based on the signals obtained, the power unit is controlled to wearer’s daily activities.
HAL suit can be used on helping people with movement disabilities, augmenting strength for difficult industrial tasks, disaster rescue, and entertainment.
Cyberdyne Corporation of Japan and Daiwa House has already started mass production and would be able to produce 400 units annually. HAL suit should be marketed at approximately $4,200 US dollars.
