(a) Charged jet deviates from the straight motion track under DC electrical field; (b) nonuniform fibrous structure deposited on insulating PET substrate under DC electrical field. Experimental condition: kV, mm, μL/hr, and wt%; (c) stable straight jet under AC electrical field on the insulating substrate; (d) uniform fibrous structure direct-written on insulating PET substrate. Experimental condition: wt%, kV, kV, Hz, %, mm, μL/hr,and mm/s.
