An engineer's answer to an ordinary fall

Magic Shields began with a motorcycle crash, a grandmother’s fracture and a stubborn engineering question: why should a floor be hard at the one moment it matters most?

Simo built machines that protect people at speed

Hiroshi “Simo” Shimomura spent years at Yamaha Motor developing racing motocross bikes, with a Master’s in robotics engineering and a career built on impact absorption. When a close friend was badly hurt in a motorcycle accident, he began inventing protective devices on his own time. When his grandmother fractured her hip in an everyday fall, became bedridden and passed away, the mission found its true shape.

One ordinary fall changed the course of her life. He decided it shouldn't have that power.
