MIT researchers have invented a way to integrate “breadboards” — flat platforms widely used for electronics prototyping — directly onto physical products. The aim of these 3D printed CurveBoards is to provide a faster, easier way to test circuit functions and user interactions with products such as smart devices and flexible electronics.

Breadboards are rectangular boards with arrays of pinholes drilled into the surface. Many of the holes have metal connections and contact points between them. Engineers can plug components of electronic systems — from basic circuits to full computer processors — into the pinholes where they want them to connect. Then, they can rapidly test, rearrange, and retest the components as needed.

But breadboards have remained that same shape for decades. For that reason, it’s difficult to test how the electronics will look and feel on, say, wearables and various smart devices. […]
