The result indicated that the DMAEMA monomer content and the pressure could significantly influence the electric sensitivity of hydrogel. With the increase of the DMAEMA content and the non-contract electric field, the Poly(AMPS-co-DMAEMA) hydrogel first bended toward the cathode and then bended toward the anode.
