#MEMS: "Sensors In Drivers Ears Makes Sunday's Indy 500 to be Safest Yet"

This weekend’s Indy 500 (May 27) could be one of the safest in U.S. auto racing history by combining 200-mph race cars with emerging MEMS technologies.


Along with new safety features created by IndyCar engineers, MEMS sensors like the three high-G accelerometers inside each driver’s earpiece will be used to detect concussions. The same high-G sensors may eventually be used by NASA to protect astronauts from hard splashdowns.


IndyCars are now equipped to stream data from three high-G accelerometers into black-box accident recorders looping through a 90-second memory. In an accident, the system shuts down on impact. After a crash, accelerometer data from 30 seconds before and 60 seconds after impact are correlated with head injuries. Accident data can then be used to improve IndyCar cockpit safety.
