Laser Induced Forward Transfer (LIFT) of nano-micro patterns for sensor applications

The current research and market trends in sensor technologies require fast, low-cost processing, reliable and accurate deposition techniques for the fabrication of sensor devices, while there is a growing need for advanced integration complexity with reduced component size. Laser printing technology has progressed during the last few years not only in organic and flexible electronics but in sensors as well, owing to its unique advantages that include the high spatial resolution, the ability to transfer materials both in liquid and solid phase, the non-destructive approach of the deposition and the need for small volume solutions and waste fluids. This review article will focus on discussing the mechanisms of laser printing and specifically of the Laser Induced Forward Transfer technique, its origins and evolution providing examples on the applicability of the technique in sensor devices. Furthermore, a comparison with other printing techniques will be presented, aiming to provide a more complete view in the field of chemical and biological sensors. (C) 2017 Elsevier B.V.
