Wearable Robot Skin Could See Missions In Space Or On People

Purdue University engineers are working on what they call robotic fabrics that can change shape to perform different functions. 

The material is a cotton fabric with flexible polymer sensors and actuators made of shape-memory alloy that bends and contracts when electric current is applied. The system can constrict around an object if the actuators are aligned in one direction or bend the object if aligned another way.

Cover of Konstantin Tsiolkovsky’s 1914 version of “Исследование мировых пространств реактивными приборами” (“The Exploration of Cosmic Space by Means of Reaction Devices”), initially published in 1903. This was the first text to seriously demonstrate the possibility of spaceflight, outlining several foundational principles of rocketry, including the use of a multistage rocket fueled by liquid oxygen and hydrogen.

I’d just like to point out the fact how cool is that Canadians put science related imagery on their money instead of old geezers who were mainly politicians.
