Although electrospinning (ES) allows the production of unsurpassed nanoscale polymer fibers, the major drawbacks are the nozzle-clogging and single-jet spinneret, respectively. This is a real limitation in terms of usable polymers and for patterning active organics. Nowadays the micro-engineering of smart materials could represent a new route for many fields of technology ranging from the production of electronic and photonic devices 1− 3 to regenerative medicine and tissue engineering. 4− 7 An enormous technological interest is related to the possibility of patterning fibers directly in well-ordered patterns avoiding the deposition of nonwoven submicrometer mats often occurring in ES. 8, 9 In the past decade several attempts have been made using fieldinduced 10− 13 and near-field ES, 14, 15 but only very recently, with the introduction of mechano ES, 16 has the production of wellordered fiber patterns been …
