Laser Folds Tiny Origami for US Army

Lasers could help fire weapons or set off explosive warheads for the U.S. Army in the near future. That possibility comes from a lab demonstration of how a simple, handheld laser can fold tiny metallic structures in a style that mimics Japanese origami.

The demonstration suggests that similar systems could produce tiny grippers and switches that would act as mechanical components in small devices. The components could be used to detonate explosive or propellant material, attach identification transponder tags to clothing, or even enable a new generation of extremely tiny robots or electronic devices.
