Abstract

We present experimental results concerning liquid crystals microdroplets behavior onto functionalized lithium niobate substrates covered with Polydimethylsiloxane (PDMS) polymer. Droplets are fragmented, driven, and reassembled by electric fields generated by pyroelectric effect. We analyze the dynamics of the observed phenomena and suggest possible technological applications.
