Courtney Webster, a biomedical engineer with the Army Research Laboratory, or ARL, is in the middle of testing with her team the prototype “Energy Harvesting Backpack” at the Soldier Performance and Equipment Advanced Research, or SPEAR, facility here.

HOW IT WORKS

A frame mounted to the standard-issue assault pack contains a two-spring, rack-and-pinion suspension system that allows it to gently glide up and down as the Soldier is walking or running, Webster said.

As the assault pack moves, the mechanical energy produced by the motion recharges the Soldier’s battery, she said.

MEASURING ITS EFFECTIVENESS

The SPEAR facility, which resembles a warehouse about the size of a basketball court, has the requisite …Read the Rest
