Considering the effects on its sensitivity, the design method of a fingertip's six-component force transducer based on the Stewart platform is discussed in detail . The relationships between the applied force and the strain of the force transducers are analyzed and the sensitivity evaluation criteria of the transducers are defined. The effects of the design parameters on the sensitivity evaluation criteria of the transducers are investigated, which is very important for the optimal construction design of the fingertip's six-component force transducers based on the Stewart platform.
