Smart tattoos that work as a sensor on any surface
While tyre pressure and breathing patterns are very different systems, the two could soon be measured using the same device. The sticker also contains zinc oxide nanotransistors on silicon wafers thinned down to microscale dimensions for maximum flexibility. Dr Hussain and his team also found a way to make the sensors work on multiple applications by using inkjet printing to write conductive wiring patterns on surfaces like paper or clothing, allowing the stickers to be attached and detached to any location. Dr Hussain and his team also found a way to make the sensors work on multiple applications by using inkjet printing to write conductive wiring patterns on surfaces like paper or clothing, allowing the decals to be attached and detached to any location. Current devices to measure sleeping patterns are heavy and uncomfortable to wear, but the e-stickers could provide a comfortable and cheap alternative Dr Galo Torres Sevilla, another author of the study, said: 'You can place a pressure-sensing decal on a tyre to monitor it while driving and then peel it off and place it on your mattress to learn your sleeping patterns.'
