Engineers from MIT have created a 3D printing technique that involves the use of a new kind of ink made from "genetically programmed living cells." As a result, the cells are made to light up in response to a variety of stimuli.
To demonstrate the capabilities of this printing process, MIT engineers created a thin, transparent patch with cells arranged in the shape of a tree. After a test subject’s hand was covered in different chemical compounds and the living tattoo patch was placed on top, the branches of the tree began to light up due to a response between bacteria and the chemical stimuli. With this technology, researchers say that the technique may "be used to fabricate 'active' materials for wearable sensors and interactive displays."
