A challenge to wearable technologies is that they’re typically not flexible – so they have to be embedded in something that can be strapped to your wrist, arm, head, or carried in your pocket or on a chain. An advance in conductive printing technology could change that.
Researchers at the University of Tokyo have designed a flexible conductive ink that can be printed on textiles in a one-step printing process.
The ink is made of silver, rubber and organic surfactants and solvents. It can be stretched 3X and still maintain its conductivity.
This opens the way to flexible sensors that could be printed on anything that needs to flex – clothing, shoes, headbands or even asphalt or EPDM roofing materials!
