Tattoos of the future
A team from MIT and Microsoft Research have developed metallic temporary tattoos that can act as an interface on your skin. Called Duoskin, the wearable tech can act as a tracking pad that could, for example, control music volume on a smartphone. The key to the tattoo’s ability is the conductive gold leaf material used to form the circuit. Accompanied by tattoo paper silicone, touch electrodes are attached to the gold leaf design and a capacitive touch controller. The information from the tattoo is then transmitted via Near-far Communication (NFC) to a device. The team also developed a tattoo that changes colour relative to body temperature and one with in-built LED lights.
Temporary tattoos could be the future for controlling our smartphones
