If you are the kind of person who forgets to drink enough water, you might find this texting coating technology interesting. While you might have heard of heat-sensitive apparel before or smart jewelry that can inform you of your body's functions, this fashion invention was designed to detect dehydration in the wearer.
Designed by Paulien Routs, SOAK is a sweat-sensitive texting coating that warns you if you are getting dehydrated. It uses color as a visual cue. Shades of blue indicate you are well hydrated, green means your hydration level is normal, where as yellow or brown denotes dehydration. This is based on the amount of acid detected in the wearer's sweat.
SOAK is an interesting application of how the skin can be used to determine health factors.
