A photolithographic process was used to integrate the conducting polymer poly(3,4‐ethylenedioxythiophene):poly(styrene sulfonate) (PEDOT:PSS) with parylene C, yielding highly conformable electrode arrays that were only four micrometers thick (shown here to conform to the midrib of a small leaf). The arrays were sufficiently self‐supporting to allow in vivo evaluation in rats, yielding high‐quality electrocorticography recordings.
