In 2022, a rehabilitation device that, when fitted to the arm of a person suffering loss of hand function due to stroke, moves the fingers as the patient performs the action in their mind became a reality. It was developed by an innovative startup that produces such medical devices as well as avatar robots using the biosignals emitted by human muscles to reproduce their function. Masahiro KASUYA started the business with his friends in 2013, while in graduate school. He says his aim is to use cyborg technology to enable people to do what they want to do. We look at a vision for the future of humanity from a genius entrepreneur on the cutting-edge of Japanese technology.
