The measurement of mechanical displacement is of interest of fundamental and applied studies. In recent years there has been increased interest and tremendous progress to study and observe the motion of a diverse set of mechanical oscillators, ranging from macroscale oscillators to oscillators which are nanomechanical in nature, such as silicon nitride membranes, nanotubes and graphene resonators. Applications for these nanomechanical oscillators can be found in mass spectroscopy and in the measurement of small forces such as the Casimir force. Moreover these nanomechanical systems can be used to study more fundamental phenomenon such as the quantum radiation pressure noise or the coupling between the motion and the charge of a nanotube. I will discuss these applications and present our experimental results.
