Abstract

Disclosed are interfacial layers with enhanced functionalities, devices having such interfacial layers, and systems and methods of using or producing such interfacial layers and devices. An interfacial layer includes a polymer having a combination of poly(3,4- ethylenedioxythiophene) (PEDOT) and PEDOT bearing an acid moiety (PEDOT-acid). A device includes one or more electrodes, each including a substrate having a surface coated with the interfacial layer. The one or more electrodes are configured to detect one or more electrical signals generated by muscles or nerves of a subject or to apply electrical stimulation to the muscles or nerves of the subject through contact with the skin of the subject.
