Ultrathin, Soft, Bioresorbable Organic Electrochemical Transistors for Transient Spatiotemporal Mapping of Brain Activity (Adv. Sci. 14/2023)

Abstract

Organic Electrochemical Transistors This cover demonstrates a bio-tissue compatible and biodegradable electronics neural interface for efficient monitoring and recording of brain activities. The neural interface features with the formats of ultra-thin, soft, and conformal mounting on brain, which allows high-fidelity recording ability. Besides, the biodegradable property appears in the cover as these scattered points around the device, referring to the tiny fragments of the device, as well as the water and carbon dioxide produced during degradation. This biodegradable electronics-based neural interface suggests an intuitive, facile and efficient methods to a broad audience of researchers in the fields of materials science, microfabrication engineering, mechanical engineering, biomedical engineering, etc. More details can be found in article number 2300504 by Enming Song, Junsheng Yu, Xinge Yu, and co-workers.
