Atomic force microscopy has since its invention in the 80s become one of the most used tools for surface science and characterization. However, the alignment of the laser is a cumbersome process and the speed at which the images are acquired is oftentimes low. In this talk I will present the progress we have made to realise an integrated low-noise detector based on the principles of cavity optomechanics. The system is comprised by a triangular mechanical resonator coupled to a superconducting LC-resonator. The coupling between the two resonators is based on strain-induced modulation of the kinetic inductance of a meandering nanowire. With this system we explore a force gradient detection scheme, both theoretically as well as verify our results with experiments.
