Cyberdyne’s Hybrid Assistive Limb ( HAL) is a powered exoskeleton suit developed by Tsukuba University in Japan. It has been designed to expand and improve the physical capability of its users, particularly disabled people. HAL uses skin sensors to detect electrical commands as they travel from the brain to the muscles, and the suit moves the body even before the muscles move.

The HAL suit is currently available for rental/lease by medical institutions throughout Japan.
