Iron-on patches can repair clothing or add personal flair to backpacks and hats. And now they could power wearable tech, too.

An Iron-on Electronic Circuit to Create Wearable Tech

Researchers reporting in ACS Applied Materials & Interfaces have combined liquid metal and a heat-activated adhesive to create an electrically conductive patch that bonds to fabric when heated with a hot iron. In demonstrations, circuits ironed onto a square of fabric lit up LEDs and attached an iron-on microphone to a button-up shirt.
