Paper Abstract
Here the pyroelectric functionality of a Lithium Niobate (LN) substrate is used for non-contact manipulation of liquids.
In this work we introduced the use of a pyro-electrohydrodynamc (PEHD) dispenser for the manipulation of high viscous
polymer materials leading to the fabrication of arrays of microlenses. The set-up used for the experiment is described and
the fabricated microlenses are analyzed by means of the Digital Holography (DH) set-up in transmission mode and
through profilometric analysis. PMMA based ink was employed for the realization of optical quality microsctructures
whose geometrical properties and, hence, the focal lengths were controlled by modifying the printing configuration of
the PEHD method. The profilometric results are in agreement with those calculated using the digital holography
technique.
