All Printed Flexible and Morphing Electronics
Heat-driven shape memory polymers (SMPs) can revert to a memorized geometry once they reach the phase-transformation temperature. This work merges the fused filament three-dimensional (3D) printing and nScrypt microdispensing to create morphing and flexible electronics that could result in innovations in antennas and sensors for biomedical and aerospace applications. Polyurethane and polylactide will first be printed simultaneously on a 3D printer to form SMPs. The thermomechanical properties of the printed SMPs will then be characterized for different TPU/PLA ratios. By nScrypt printing silver electrodes on the SMPs, a morphing antenna will eventually be prototyped and characterized.
