摘要
The present invention is directed to the production of stretchable wrinkled film electrodes for use in wearable/portable ROC systems using electrochemical analysis techniques. A polymer layer is disposed on a conductive substrate and a sacrificial layer is disposed on said polymer layer. An electrode shape template is cut out of adhesive and disposed on the sacrificial layer. A metallic film is disposed on the sacrificial layer by the electrode shape template. The disposed layers are removed from the conductive substrate and placed in an oven to allow said layers to shrink. The shrunken metallic film is treated with a solution to promote bonding between the film and an elastomer. The elastomer is drop-cast onto the shrunken film and the sacrificial layer is dissolved to detach the shrunken polymer layer. The shrunken film and elastomer are placed in a chemical bath and dried, producing the stretchable wrinkled film electrode.
