Fig. 2From: Characterization of 3D electrospinning on inkjet printed conductive pattern on paperAnalysis of factors affecting electrospun fiber stacking through modeling and electrospinning experiments. a Electric field calculated through Eq. (1) for continuous and controlled jet ejection. b, c SEM and CCD camera images of stacked fibers on the conductive pattern when high electric field and low electric field were applied respectively. Through image confirmation, it is possible to confirm that the fiber is well stacked (b) or not (c)Back to article page
