Images of CFM and CNF electrodes. Photographs of (a) CFM and and (c) CNF devices after fabrication. Scanning electron microscopy images of (b) CFM encased in a borosilicate capillary and (d) CNF-based 3 × 3 sensor pad array. High-resolution scanning electron microscopy images of (e) CNFs on a sensor pad prior to dielectric encapsulation and (f) CNFs on a sensor pad after dielectric encapsulation. Scale bars are 20 µm, 800 µm, 2 µm and 5 µm, respectively. An imposed tilt of 30° was utilized in (e).
