Animals’ natural defenses are providing inspiration for researchers developing the next generation of lighter, tougher body armor.

Benjamin Bruet, a graduate student in engineering at the Massachusetts Institute of Technology in Cambridge, is part of a team funded by the U.S. military to create new materials to protect soldiers in the field.

New Backpack Generates Its Own Electricity

Publication: National Geographic News   Date: September 8, 2005   View Article

A backpack that generates its own electricity may soon allow rescue workers, explorers, and soldiers to power their equipment while on the go, a team of scientists reported today.

The backpack will derive its power from the motion of the person carrying it.

The invention, known as the suspended-load backpack, frees handheld computers, cell phones, and dozens of other devices from the constraints of limited battery life and the reach of the power grid.
