Flexible three‐dimensional printed antenna substrates

The Journal of Engineering, 2015
Flexible heterogeneous substrates have been constructed, using three‐dimensional printing in a single process, by introducing air‐filled slots. These substrates have been used to substantially reduce the substrate losses for a flexible microstrip patch antenna causing an increase in its radiation efficiency.

Three-Dimensional (3D) Printing in Orthopedics Education

Journal of Long-Term Effects of Medical Implants, 2020
Three-dimensional (3D) printing is a newly established concept in orthopedics compared with other industries. Surgical applications of 3D printing and tissue engineering have been investigated since the early 2000s, almost two decades after Charles Hull had patented the first device currently in use for additive manufacturing, also known as rapid ...

Bioinspired Shape‐Memory Hook Fasteners With Programmable Interlocking and Silent Release

Advanced Engineering Materials, EarlyView.
Bioinspired hook fasteners made from epoxy shape‐memory polymers are shown to switch between strong, secure attachment and gentle, silent release when heated. By combining programmable geometry and material response, these adaptive fasteners outperform commercial systems in strength and noise control, enabling new solutions for robotics, medical ...
