Force sensors are important instruments for studying the interaction between users and stimuli, and gain insight in tactile perception. This paper presents a high-precision, high-bandwidth force sensor that relies on an interferometer to achieve millinewton precision over a frequency bandwidth that spans continuous forces all the way up to 1300 Hz. The picometer resolution of the interferometer allows to design a stiff elastic structure while preserving a sufficient force measurement sensitivity.
