## Summary

Professor HyunJoo Oh of Georgia Tech’s CoDe Craft group discusses her research into 'paper mechatronics,' which integrates computing with everyday craft materials like paper. She explains how her group developed accessible sensor kits using copper tape and silver nanoparticle ink to teach engineering concepts to students, and shares the open-source PaperMech and FoldMecha tools for designing paper-based mechanical movements. Oh details the transition from her PhD work on kinetic paper sculptures to creating educational platforms that lower the barrier to entry for mechanical and electrical design.
