Reversible anemometric sticker sensor applied on finalized polymeric LoC devices

摘要

In this paper, an anemometric sticker sensor is presented, which can be used as a flag to verify the completion of a particular step inside microfluidic devices, the presence of leakages or trapped air bubbles. The similarity of the fabrication method to the printing and roll-to-roll techniques offers a simple and realistic mass-producible solution for direct monitoring of microfluidic protocols inside lab-on-a-chip devices. The detector has been fabricated on a sticker, which presents low space needs and can be easily applied on the test chip with no strict alignment requirements. The introduced idea fulfills the sensing demand that currently microfluidic devices present, being reusable or disposable due to its low cost requirements.
