Zusammenfassung:A force sensor has a first end portion, a second end portion, a parallel-guiding mechanism, a beam, and a strain gauge. The parallel-guiding mechanism connects the first end portion to the second end portion. A main beam of the beam has a flexible wall and a rigid wall. A first connecting part connects the flexible wall to the first end portion, and a second connecting part connects the rigid wall to the second end portion. The strain gauge is fixed to the flexible wall. The force sensor can measure a relatively small force.
