From: Bidirectional rotation control of a carbon fiber in nematic liquid crystal using AC electric field
Schematic diagram explaining the bidirectional rotation of CFs in the experiment. The curves are the plots of \({F}_{CF}\) from Eq. (9) by the strength of an electric field. The CF was stable at the local minima of each curve. (a) When the electric field was gradually increased from 0 V/\(\mathrm{\upmu m}\). (b) When a strong electric field of 0.09 V/\(\mathrm{\upmu m}\) was applied and then decreased steadily. In both images, the processes follow the arrows starting from the minimum of the black curve (0 V/\(\mathrm{\upmu m}\)).
