Columbia Engineering researchers announced today that they have developed the first stand-alone, conformable, fully organic bioelectronic device that can not only acquire and transmit neurophysiologic brain signals, but can also provide power for device operation.

New York, NY May 10, 2021 As researchers learn more about the brain, it has become clear that responsive neurostimulation is becoming increasingly effective at probing neural circuit function and treating neuropsychiatric disorders, such as epilepsy and Parkinson s disease. But current approaches to designing a fully implantable and biocompatible device able to make such interventions have major limitations: their resolution isn t high enough and most require large, bulky components that make implantation difficult with risk of complications.
