The piezoelectric coefficient d33 were investigated as function of PZT content, poling temperature and electric field. The highest value for d 33 coefficient was around 6pC/N for 50 vol% of PZT content in the composite. As PHB is a biodegradable polymer the composite has potential application as sensor minimizing the environmental problems.172-173engBiodegradable polymersComposite materialsElectric fieldsLead compoundsPolymer filmsCeramic powderLead zirconate titanate (PZT)Piezoelectric coefficientPoling temperaturePiezoelectric ceramicsTrabalho apresentado em evento10.1109/ISE.2005.1612348WOS:000236764500045Acesso aberto2-s2.0-3384770903410168699749881900896348165708140
