COMSOL® finite-element simulation results, fabricated serrated teeth, and electrospinning results from (A1–A5) [20 mm, 13.3 mm, 161°]; (B1–B5) [10 mm, 10 mm, 143°]; and (C1–C5) [5 mm, 10 mm, 60°] serrated teeth deign; where (A1,B1,C1) are simulated electric potential contours; (A2,B2,C2) are simulated electric field profiles; (A3,B3,C3) are zoomed-in images of electric potential contours near each tooth; (A4,B4,C4) are fabricated serrated teeth; and (A5,B5,C5) are images³² of electrospun fibers collected by each collectors.
