Abstract :
Screen-printing is a versatile and cost effective fabrication method for depositing thick-film patterns on a wide range of substrates. 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 d33 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.
