Abstract: A new method for direct patterning of Poly(dimethylsiloxane) (PDMS) structures is presented. This technique will be named Light Induced Patterning (LIP) as it’s induced by laser light through a functionalized substrate of Lithium Niobate (LN) crystal. The process is a full field technique that, conversely to the point wise ones, allows PDMS patterning with a single laser light exposure.
