There have been many approaches to designing components that can provide portable power for wearable electronics. A new study by researchers at Michigan Technological University, Arizona State University, and NanoSonic Inc. looks at how energy might be harvested from walking about with a backpack. The approach uses piezoelectric materials in the shoulder straps of the backpack, which generate power due to the differential forces between the pack and its wearer. Their goal is to develop a discreet system that is inconspicuous to the wearer and does not hamper movement, nor endurance. The paper develops a theoretical model of the piezoelectric strap and uses experimental testing to identify its performance.
