Nissan reveal dehydration detection car seats that measure your sweat 0


You certainly can’t accuse Nissan of lacking innovation. The Japanese car maker has just revealed a prototype car seat that detects driver dehydration by measuring their levels of sweat.

A recent study by the European Hydration Institute found that dehydrated drivers were just as likely to cause an accident as those who have been drinking.

With that in mind, Nissan have shown off the concept car seat, imaginatively called SOAK. The technology changes colour if the seat occupant’s perspiration is high in salt, suggesting dehydration.

The sweat sensitive coating – also applied to the steering wheel – changes from yellow to blue, depending on the driver’s levels of hydration.

Prof Peter Wells, an expert in business and sustainability from Cardiff University Business School, said that measuring additional factors which impede drivers’ abilities made as much sense as monitoring factors which affect the vehicle itself.

“This is part of the overall idea that it’s not just about monitoring the car but also the driver,” he said.

“This particular application is obviously on the edge of usefulness but it shows a willingness to think more generally about these things and find a way forward.

“I’m not sure that way of showing you are dehydrated is going to appeal to many people – but I like the concept.”

Prof Wells added that other potentially measurable factors which affect drivers could include their emotional state – perhaps by monitoring adrenaline or hormone levels.

“We are going to get more and more of this kind of thing. Many factors affect our ability to drive,” he said.
