3D-printed live bacteria creates world's first "living tattoo"

2 pictures Researchers used a 3D-printed patch of bacteria cells to create a "living tattoo" that changes color in the presence of certain chemical stimuli A team at MIT has genetically modified bacteria cells and developed a new 3D printing technique to create a "living tattoo" that can respond to a variety of stimuli. Electronic tattoos and smart ink technologies are showing exciting potential for reframing how we think of wearable sensor devices. While many engineers are experimenting with a variety of responsive materials the MIT team wondered if live cells could be co-opted into a functional use. The […]
