Researchers 3D Print Electronics on Moving Hand

In the future, you will be able to have smart wearables 3D printed on your skin. In fact, researchers at the University of Minnesota have already tested the idea using a low-cost 3D printer. The portable printer used for this project was worth less than $400.

The customized 3D printer can adjust to small movements of the body during the printing process. A specialized ink make of silver flake was used that can cure and conduct at room temperature. To remove the electronics, one simply has to wash them off.

Such an approach can be used by soldiers on the battlefield to print temporary sensors to detect chemical agents or solar cells to charge their electronics. Pretty neat, don’t you think?
