Cool Shirt Answered

Hi there - wonderful minds!
I am seeking some help here in creating a shirt that should sense the temperature or sweat and then itself sprays some coolant to cool off. Much useful in summer season ofcourse

I don't really see the point but anyway:
If you measure the body temp on a hot day with a shirt you also have to compensate for the outside temp of the shirt and the actual skin temp.
Walk from the sun into the shade and all values change instantly.
Adding water to cool down will give you a cold skin temp while the body might actually still overheat.
Well, and once the shirt is wet - how do you want to know it is sweat or colling water?
If you want to sense temperature using a color changing shirt ;)

Why? Your body has all that built-in! Temperature sensing to a tenth of a degree (either °C or °F)! Sprays coolant (aka sweat) when overheating! Can even produce heat when undercooling (aka shivering)!

We future space travellers need something like that with temperature sensing to a tenth of degree in °K! Actually, that kind of device might be useful to monitor kids or pets in a car or prevent heat injuries when overengaged in sports activities.

Sorry, but I'm compelled to object. Everything already built-in and in place for at least a few millennia. For leaving kids and pets in a car, the solution is easy: Don't. (Or technically: Once the air in the car is saturated with water, the shirt will not cool any more and kid/pet will die no matter what)

Overengaged in sports? Listen to your body and drink (or rest in the shade) or go the Darwin way (the one that's bad [aka terminal] for you personally, but good for the human race as such).

And in space - nobody can smell you(r) sweat.

Btw, a tenth of a °C is exactly the same as a tenth of a °K (not that you didn't know that already :-)
