ABSTRACT:
An electrically reactive composite article comprising a random or regular array of microstructures partially encapsulated within an encapsulating layer, microstructures each comprising a whisker-like structure, optionally having a conformal coating enveloping the whisker-like structure is described. The composite article is useful as an electrically conducting component of a circuit, antenna, microelectrode, reactive heater, and multimode sensor to detect the presence of vapors, gases, or liquid analystes.
