Transparent Heat Pad Reduces Burns

Transparent Heat Pad Reduces Burns
A new, transparent heating pad could help protect users from accidental burns.

The pad was designed with the elderly in mind, who often lose sensitivity in their skin and do not detect excess heat. To make it easier for these users to track their heat exposure, the new thermotherapy pad is made up of conductive silver nanowires that have been embedded in a polyvinyl alcohol film. The film and a copper electrode were then contained inside a transparent, biocompatible silicon. Since the pad is transparent, the patient can simply glance at their skin to see if it is getting too red.

The pad will heat quickly and can withstand being bent thousands of time, in contrast to other versions that were too expensive or too stiff.
