Abstract
We describe a method to increase the sensitivity of a resonant force s ensor. The excitation of a cantilever beam with several small sheets o f piezoelectric polymer adequately glued to it selects one high-freque ncy vibration mode of the cantilever. A higher resonance frequency lea ds to better sensitivity in force-gradient detection as examplified by the measurement of the force gradient between two magnets. (C) 1998 E lsevier Science S.A.
