Flexible organic transistors for neural activity recording

Flexible electronics capable of interacting with biological tissues, and acquiring processing information, are increasingly demanded to capture the dynamic physiological processes, understand living organisms, treat human diseases. Neural interfaces a high spatiotemporal resolution, extreme mechanical compliance, biocompatibility essential for precisely recording brain activity localizing neuronal patterns that generate pathological signals. Organic transistors possess unique advantages in detecting low-amplitude signals at physiologically relevant time scales biotic environments, given their inherent amplification capabilities situ signal processing, designable flexibility, features. This review summarizes recent progress neural stimulation enabled by flexible stretchable organic transistors. We introduce underlying mechanisms multiple transistor building blocks, followed an explicit discussion on effective design strategies toward arrays improved transduction transistor/neural interfaces.
