- 06 Dec 2016
TL;DR: The use of stretchable optical waveguides for strain sensing in a prosthetic hand using optoelectronic strain sensors that are easy to fabricate, are chemically inert, and demonstrate low hysteresis and high precision in their output signals is reported.

Poroelastic Foams for Simple Fabrication of Complex Soft Robots
Benjamin C. Mac Murray,Xintong An,Sanlin S. Robinson,Ilse M. Van Meerbeek,Kevin O'Brien,Huichan Zhao,Robert F. Shepherd +6 more
TL;DR: Open-celled, elastomeric foams allow the simple design of fully 3D pneumatic soft machines using common forming techniques and an entirely soft, functional fluid pump formed in the shape of the human heart is demonstrated.
