Short summary
We tested two types of home-made sensing elements – four coupled silicon micro-levers and a multilayer graphene membrane – which have the potential to further enhance the sensitivity of laser photoacoustic spectroscopy. Graphene sheets possess outstanding electromechanical properties and demonstrate impressive sensitivity as mass detectors. Their mechanical properties make them suitable for use as micro-/nano-levers or membranes, which could function as extremely sensitive pressure sensors.
