Skin

Student researchers have developed a 3D-printed electronic skin that can flex, stretch and sense like human skin, opening the door for new advances in human-machine interaction.

The technology could be used to print temporary sensors on the bodies of soldiers, for example, to detect chemical or biological weapons. Printed solar cells could also be used to charge electronics.

New method said to be around 50 times cheaper than alternative methods and requires 10 times less base material.
