It has been used in printing electronics on flexible substrates such as films, papers and textiles. This paper presents a low temperature screen-printable PZT/polymer paste consisting of PZT powder, high dielectric constant polymer binder and solvent. The optimization of the PZT/polymer weight ratio (12:1) and poling process (90 °C, 6 minutes and applied electric field of 3.75 MV/m) achieved a d 33 of 40 pC/N. Also, the material has a Young's modulus of 131 MPa and is very flexible enabling it to be exploited in e-textiles applications for energy harvesting and sensing. I. INTRODUCTION Researchers have shown a great attention to piezoelectric materials that can be used in sensing and actuating applications. The generation of charge due to an applied mechanical stress (the direct effect) is exploited in sensors and energy harvesters. The generatio...
