ECG electrode based on CNT/aPDMS.

(a) The aggregated CNTs are mixed with aPDMS by using flow stress. The CNTs are in electrical contact, which means that CNT/aPDMS is conductive. (b) A SEM image of CNT/aPDMS after removal of some aPDMS with THF solution. (c) Conformal contact of CNT/aPDMS with wrinkles and rough skin and (d) a SEM image of a CNT/aPDMS electrode attached to a PDMS skin replica. (e) Structure of an ECG electrode composed of a PDMS base, a metal-patterned layer (Au/Ti/PI), a frame layer (aPDMS) and a CNT/aPDMS interfacial layer. (f) Upper surface of the ECG electrode and serpentine lines. (g) Bottom surface of the ECG electrode, which is the surface attached to the chest.
