“DuoSkin is a fabrication process that enables anyone to create customized functional devices that can be attached directly on their skin. Using gold metal leaf, a material that is cheap, skin-friendly, and robust for everyday wear, we demonstrate three types of on-skin interfaces: sensing touch input, displaying output, and wireless communication.” ~ MIT
The research team has proposed that the tattoos could be used as trackpads, medical related temperature sensors, or extraction of health data. All three of these uses are promising and could pose massive advances in their respective industries. Believe it or not, the team is capable of creating tattoos with LEDs embed in them that can be controlled by the circuit as well.

Rather than being permanent, these tattoos are applied and last just about as long as temporary tattoos. Advancement in the application and use of the tattoos will enable them to last much longer and be implemented in people’s everyday life. These smart patches could change how we interface with out devices, and responding to that text could become as simple as massaging your arm.
