Engineers at the MIT have developed a 3D printing technique for genetically modified bacteria cells to create a “living tattoo”.

A team of MIT engineers have developed a 3D printing technique that makes use of a an ink made from genetically programmed living cells. These cells are designed to light-up in response to a number of stimuli. When tested on a human hand that had been applied with different target chemicals, the patch successfully illuminated its tree-like branches as it detected the corresponding chemicals. According to MIT News, “the technique can be used to fabricate “active” materials for wearable sensors and interactive displays.”

Research and development into creating smart materials have been ongoing for decades. These materials are expected to be capable of responding to heat, chemical stimuli, and much more. For instance, a smart material that is responsive to heat can be used to create moving or self-assembling robots; those responsive to chemicals can be deployed in chemical sensors, etc.
