Ferrari Press Agency Ref 8709 Tattoo 1 06/12/2017 See Ferrari text Picture MUST credit : Massachusetts Institute of Technology A living tattoo that can warns wearers about environmental pollution and temperature changes is being developed by researchers.It opens the door for the developmnt one day of living computers, it is claimed.The tattoo is made of modified bacteria cells and uses a new 3D printing technique.A team from the USA???s Massachusetts Institute of Technology looking at wearable sensor devices wondered if live cells could be co-opted into a functional use.The first step was to look at what organic cells could be utilized.They discovered the strong cell walls of bacteria were best as they could survive the force of a 3D printer's nozzle. Bacteria also proved to be perfectly compatible with the hydrogels needed for accurate 3D printing.To test out the technique the team created a 3D-printed patch of bacteria cells on a thin polymer strip known as an elastomer layer .This layer was designed to resemble a tree. The bacteria in each branch of the tree was engineered to respond to a different chemical stimuli. When the patch was tested on a human hand that had been applied with different target chemicals the bacteria successfully illuminated its branches when sensing the corresponding chemical.The ultimate outcomes for the technology are incredibly futuristic, with the team suggesting the technique could conceivably lead to the development of a kind of "living computer." Complex structures could be created that contain many different types of engineered cells that communicate with each other in the same way as transistors on a microchip.MIT study co-author Hyunwoo Yuk said:"This is very future work, but we expect to be able to print living computational platforms that could be wearable.???More immediate, pragmatic uses include the development of warning stickers that contain cells engi
