Neural probes 3D printed for softer, more flexible implants

A team of researchers from Massachusetts Institute of Technology (MA, USA) has 3D printed soft, flexible neural probes as a potential replacement for the traditionally used rigid, metal probes. A team of researchers from Massachusetts Institute of Technology (MIT; MA, USA) has developed 3D-printed neural probes for softer, flexible neural implants to replace traditional metal, rigid implants that can cause inflammation and scarring. Outlined in Nature Communications, the devices are made from an electrically conductive polymer that can form stable, electrically conductive patterns once 3D printed. Having implanted one device into the brain of a mouse, the team reported to...
