Using a 3D-printing process called microstereolithography, researchers at MIT, in collaboration with Singapore University of Technology and Design, have created small structures that respond to temperature while remembering their original shape. Printed with a polymer mix that hardens or softens with temperature, the objects can be contorted, yet return to their initial shape. Applications for the technology include medicine, aerospace engineering, and even pharmaceuticals. “We ultimately want to use body temperature as a trigger,” says Nicholas Fang, associate professor of mechanical engineering at MIT. “If we can design these polymers properly, we may be able to form a drug delivery device that will only release medicine at the sign of a fever.” [Engadget + MIT News]
