Power Through Motion
Credit-card-sized origami-inspired folding devices that generate electricity through the physical motion of folding and unfolding. Each fold produces power through embedded piezoelectric and triboelectric layers.
You're stranded with a dead phone in an airport. You pull out a slim card from your wallet, snap it open with a satisfying fold, and watch your phone screen light up and start charging — no outlet, no solar panel, no waiting — just the power of your own hands folding a piece of paper-thin material.
