Organic transistor technology holds great promise for creating a conformal, human-safe electronic neural interface. These interfaces must amplify the low, microvolt-range brain signals so they can be utilized in analog and digital applications. Brain signals from sensors must be relayed to the transistor’s gate through the dielectric and semiconductor layers, as well as through an encapsulant w...
