Inkjet-Printed Piezoelectric Polymer Actuators

All inlqet-printed piezoelectric polymer actuators based on copolymers from vinylidene fluoride and trifluoroethylene have been developed. The electrodes are printed from silver nanoparticle dispersions (27). [Pg.221]

These devices can be used as actuators for membrane pumps for microfluidic lab-on-a-chip systems. For manufacturing these actuators, a low-cost method is employed that involves only three inkjet printing and post-processing steps. [Pg.221]

Further, moderate thermal treatments at a maximum of 130°C and plasma sintering are employed. Therefore, the method can be used for a wide range of temperature-sensitive pol5mer substrates. [Pg.221]

In particular, a sandwich-like structure of a piezoelectric layer from the copol5mer between two silver electrodes is inlqet-printed onto a PET substrate. [Pg.221]

When a voltage is applied across the piezoelectric layer, a bending deflection is observed. For the application in a micropiunp, flow rates of several 100 ylmin are desirable (27). [Pg.221]
