Polymer-Based 2D-to-3D Transformable Surfaces

Technologies using stretchable materials are increasingly important. Yet, in general, it is not possible to control how they stretch with much more sophistication than inflating balloons. A method was developed that allows the calculated transformation of 2D stretchable surfaces into targeted 3D...

Soft robots inspired by nature can crawl, swim, grasp delicate objects, and even assist a beating heart, but none of them has been able to sense and respond to the...

A “4D printing” method was developed for a smart gel that could lead to the development of living structures in human organs and tissues, soft robots, and targeted drug delivery.

Microphones, from those in smartphones to hearing aids, are built specifically to hear the human voice — humans can’t hear at levels higher than 20 kHz, and microphones max out at...

Engineers Put 'Spring' in Robots' Step

The ATRIAS robot model developed at Oregon State University uses a "spring-mass" walking approach. The natural-gait method gives human-sized bipedal robots the ability to blindly react to rough terrain, maintain balance, retain an efficiency of motion, and walk like humans.
