3D Printed Multi-Point Capacitive Touch Sensing

Designing interactive devices is a challenging task that requires careful mechanical design and wiring to integrate electronics. Using multi-material 3D printing and computational tools, this work demonstrates an approach to generate and fabricate conductive traces within objects to support capacitive touch sensing. Touching different parts of an object produces a unique delay in the electrical signal across the integrated electrical circuit. The signal delay allows users to sense exactly where someone touches an object.
