Abstract

ABSTRACTA new concept of pyroelectric electrohydrodynamic system for deposition of the micron size droplets at the predetermined position on the substrate with high accuracy using pyroelectric field created by lithium tantalate with tailored domain structure has been proposed. The optimal geometry of the domain pattern has been obtained by computer simulation of the spatial distribution of surface pressure acting on liquid/vapor interface induced by pyroelectric field. The proposed technique was applied to dispense the silicon oil and the water solution of amino acid glycine.
