Abstract : The bidirectional force sensor was made by sticking the strain gauge on the elastic beam. The bridge was com2 posed of the bridge with two couples of strain gauge ,to feel the force from two directions. Using the FEA to analyze and simulate ,an elastic beam structure to measure the two directioal force was introduced and validated by experiments. The sensor with the elastic beam has high sensitivity ,simple structure ,and sensor was applying to the measurement and con2 trol of the manual component.
Key words : force transducer ; elastic beam; equal intensity beam; finite element analysis(FEA)
