Abstract
Abstract: We describe a method to increase the sensitivity of a resonant force sensor. The excitation of a cantilever beam with several small sheets of piezoelectric polymer adequately glued to it selects one high-frequency vibration mode of the cantilever. A higher resonance frequency leads to better sensitivity in force-gradient detection as examplified by the measurement of the force gradient between two magnets.
