Kent State University researchers have developed a fabric that can be turned into a sensor sock for diabetics.
The liquid crystal in the prototype sock changes color depending on body temperature. Inflammation, swelling and infection cause an increase in temperature, and poor circulation causes a decrease in temperature. This is a simple way to detect changes early and avoid significant diabetic complications.
Patients put the socks on in the morning. If they notice a color change, they are prompted to call their doctor. The most common change would be to blue or green, indicating heat.
