The invention relates to a multidimensional force / torque sensor, which comprises a hollow framework, a loading platform, a plurality of laminar first elastic beams, a plurality of laminar second elastic beams, a force transferring block and a strain gage group, wherein the loading platform is suspended in the framework, the two ends of each second elastic beam are connected with the framework, thesecond elastic beams and the corresponding first elastic beams are connected at a preset angle, the corresponding first elastic beam is divided into two mutual perpendicular parts in width directionby the force transferring block, two sides of the force transferring block are respectively connected the two parts of the first elastic beam correspondingly, and the distances of the force transferring block away from the center of the first elastic beams are different. The thickness of the first elastic beams is thinned, thus reducing the influence on other beams; the first elastic beams are divided into two parts through the force transferring block, so that the elastic deformation of the first elastic beams can be effectively generated on any one of the two parts, and the detection dimension can be increased while the multi-component coupling is reduced. The distances of the force transferring block away from the center of the first elastic beams are different, so that the pasting positions and quantity of strain gages can be increased, and the detection dimension can be increased.
