114. The Big Deal In (Smart) Diapers

The Next Byte Podcast · 21 Mar 2023 · 20m

What this episode covers

Hosts Daniel and Forbode discuss a flexible humidity sensor developed by researchers at Penn State University that enables smart diapers and other health monitoring applications. The sensor is created by spraying paper with a sodium chloride (salt) solution and drawing a circuit with a pencil, leveraging graphite and ionization to detect moisture. The hosts explore its ability to monitor breath patterns for respiratory health, skin humidity for dehydration detection, and its potential for low-cost touchless sensing interfaces.

    394: Being Four-Year-Olds

    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.
