We all know Formula 1 is a test bed for a variety of technologies that will eventually trickle down to the street. Now, McLaren is taking its go-faster know-how and applying it somewhere a bit unexpected – health care. The body armor you see here was created in response to a client’s request for a device that would help keep his organs protected after undergoing surgery. It’s called Invincible shield, and it protects the rib cage through the use of high-failure strain Dyneema fibers, as well as woven fabrics and a highly-toughened resin system. The construction and materials pull from McLaren’s F1 experience, and includes the same fibers used as side-impact crash protection in the race car. Essentially, this armor is made from the same stuff that’s going into next year’s F1 competitor.
