Abstract

Mechanical elements are successfully employed as force sensors in various devices. The sensors have reached impressive sensitivity of few nN/sqrt(Hz), but the quest for even more sensitive sensors is still on. The capability of sensing a single bacteria stuck to the sensor's surface in few seconds would provide unprecedented possibilities in various fields. Even in physics such sensitive sensors could be used in search for the elusive constituents of the dark sector. A possible interaction of either dark energy or dark matter with the sensor could be detected. A characterisation of an optimised sensor element will be presented along with it's properties.
