The newly developed shape memory polymer resist which allows for high-resolution 4D printing, promises a platform for information hiding for optical anti-counterfeiting and tunable photonic devices.

The Singapore University of Technology and Design (SUTD) and its research collaborators have successfully demonstrated the four-dimensional (4D) printing of shape memory polymers in submicron dimensions which are comparable to the wavelength of visible light. This novel development has allowed researchers to now explore new applications in the field of nanophotonics.
