A Possible Fix for 3D-Printed Objects: Separate the Sensor Material From the Wiring
Researchers at CSAIL and Tianjin University in China may have found a way to 3D-print more precise interactive objects. The sensors and the wire-like elements have typically been made from the same material, so they emit similar signals.
Their X-Hinges software automatically embeds two different materials: a filament for the sensors, designed to send the strongest signal possible, and another for the wire-like elements that don't interfere. That lets a printed item use up to three axes of motion—compressing, up and down, or to the sides—instead of the single axis of earlier approaches.

The interesting part isn't the hinge; it's the accounting. One material has to be loud for sensing, the other quiet enough not to drown it out.
Quiet is doing a lot of work there. The traces are still conductive elements, so the second material has to be useful for wiring without broadcasting over the sensor.
