Carbon micro-coils (CMCs) with 3D-helical/spiral structures and coil diameters of orders were obtained by the metalcatalyzed pyrolysis of acetylene at 700-800°C. In this review, the preparation process, morphology, microstructure, properties, and some applications of CMCs are introduced and their future prospect is discussed. The as-grown CMCs have almost amorphous structure, but were graphitized by high temperature heat treatment with full preservation of the coiling morphology. The CMCs could effectively generate inductive electromotive force, inductive current and thus Joul's heat under the application of microwaves. The CMCs/elastic polymer composite elements showed high tactile/proximity sensing properties which are comparable to that of human skin. The CMCs are a possible candidate for electromagnetic wave absorbers, remote heating materials, visualization elements of microwaves, tactile/proximity sensor elements, micro-antenna, chiral catalysts, bio-activators or bio-deactivators, energy converters, etc.
