Falling asleep while driving is a common occurrence. According to the National Highway Traffic Safety Administration (NHTSA), each year, more than 100,000 police-reported car accidents result from drivers who fall asleep. This is most times caused as a result of inadequate sleep or tiredness, can you rely on yourself to know when you are too tired to drive? irrespective of your answer, there’s now a shirt that helps you to monitor that.

This shirt was created by Japanese company Toyobo, the company teamed up with Union Tool to create ‘Cocomi’, a drowsiness detecting shirt that identifies a specific pattern of electric signals of the heart which indicate the onset of sleep. This was achieved using Toyobo’s high-tech Cocomi material and Union Tool’s “Safe Driving Support Tool Drowsiness Notifier DSD”.

Cocomi is about 0.3mm thin and has low electrical resistance, it can collect high-accuracy biological data and has high precision and conductivity.

According to the Japan Times, the Cocomi undershirt is currently being tested in parts of Japan by the Chuichi Rinkai Bus Company, many drivers that work long hours use the sleep-detecting clothing. When in use, the shirt should sense changes in the user’s biometrics then sound an alarm to alert the driver if necessary.

Cocomi is set for a full release later this year
