--Piezoelectric nanogenerators (PENG) are used to monitor physiological signals. PENG are made of piezoelectric material and zinc oxide is a promissory material due to its biocompatibility; however, its electrical output is not competitive compared to lead-based materials. Doping and morphology control are strategies for to reduceing this disadvantage. In this paper, electrodes were developed using a textile, and commercial ink and zin oxide. Polyvinylidene fluoride (PVDF) modified with zinc oxide was evaluated to be used as piezoelectric generator
