Electroactive polymers for printed organic electronics, Piezotech RT terpolymer P(VDFco-TrFE-co-CTFE) Arkema, France and dimethyl sulfoxide (DMSO) was purchased from Sigma Aldrich and used as received. The polymer was dissolved in DMSO at 30 wt% and stirred using a spatula in an Eppendorf tube at room temperature. The viscous fluid was introduced into a 3 mL syringe that could then be placed in the printer.
