The invention discloses a dielectric electrophoresis-based arrayed liquid crystal sensor, comprising an upper sidewall and a lower sidewall, wherein the peripheries of the upper sidewall and the lowersidewall are sealed and form a chamber for accommodating liquid crystal droplets, and the upper sidewall and the lower sidewall are correspondingly provided with array electrodes. By providing arrayelectrodes correspondingly on the upper sidewall and the lower sidewall of the dielectric electrophoresis-based arrayed liquid crystal sensor provided by the invention, when the liquid crystal droplets are introduced into the chamber, the array electrodes are energized, alternating electric fields are correspondingly formed on the upper sidewall and the lower sidewall, the liquid crystal dropletsmove to the same spatial plane under the action of the electric field force and form a regular patterned array arrangement, and the final arrangement effect is related to the distribution of the arrayelectrodes, so that the array arrangement effects of different liquid crystal droplets can be realized by changing the arrangement mode and spacing of the array electrodes, that is, the constructionof the array of the liquid crystal droplets can be realized under the effect of dielectrophoresis.
