Nissan has developed sweat-sensitive car seats that turn a different colour if the driver is dehydrated.
It’s supposed to work as a safety feature, as dehydrated drivers can make as many mistakes as those who are over the drink-drive limit.
So the car manufacturer has produced a prototype material which they’re calling Soak, that coats the steering wheel and front seats and changes colour depending on the hydration levels of the driver’s sweat.
Dr Harj Chaggar, a medical consultant for Nissan Motorsport, said: “While many athletes are well-versed on keeping hydrated, many people outside the sporting sphere remain unaware of the impact of dehydration on physiological performance.
“Sweat-sensing technology built into a car is an innovative way of highlighting this, aiding prevention by warning the driver directly.”
Nissan is not currently planning to add Soak technology to their vehicles.
