A portable cooling device on your wrist.

txrlmlerke

Hi Ben

 

I been trying to power a peltier cooler to wear on your wrist to cool the body down. it needs to be small like a in wrist sweet band.. the problem I have designing it is the power. my question is can a peltier be power with a 3 v coin battery and made rechargeable? or you can make it on your show.

    Amazing - you would definitely be better off with just the fan - except possibly if the air temperature was above 37C. I think the fan blowing on wet skin (sweat will do) will beat the peltier up to much higher temperatures.

     

    It is actually very difficult to measure the cooling effect on a human of this thing or a direct fan so comparing them will be subjective - I look forward to hearing about the OP's results.

     

    @ Robert - note the size of battery in the video.
