Oregon scientists use 3D printed nerve tingling device to better understand birdsong 

Researchers from the University of Oregon (UoM) have developed a 3D printed device that’s capable of recording and stimulating the electrical impulses that drive vocalizations within songbirds.  The team’s microscopic device, featuring a tiny thin-film electrode with a 3D printed housing, functions by decoding and modulating electrical signals sent to either the brain or spinal cord.
