A system for developing a composition for powder molding which, after a viscosity of the composition for powder molding and a degreasing process, extracts optimal compositional information of the composition in terms of the ratios of the residual binder materials is disclosed. Such a system includes a searching logic unit configured, after generating a plurality of candidate compositional information, to extract the optimal compositional information therefrom and a synthesis/analysis module configured to synthesize and analyze compositions corresponding to the plurality of candidate compositional information and provide to the searching logic unit measurement information on the viscosities of the compositions corresponding to each of the plurality of candidate compositional information and ratios of residual binder materials after a degreasing process. Also, the searching logic unit extracts the optimal compositional information based on the candidate compositional information and the measurement information thereof.

System and method of developing composition for powder molding

A strain sensor with color emission indicating a strain is disclosed. The strain sensor can include a piezoresistive layer having a first portion of a polymer matrix body and conductive fillers dispersed in the first portion of the polymer matrix body, a mechano-luminescent layer having a second portion, which is disposed on the first portion, of the polymer matrix body, green emissive particles, and red emissive particles, the green and red emissive particles being dispersed in the second portion of the polymer matrix body, and a first and second electrodes spaced apart from each other and directly connected to the piezoresistive layer.

Strain measurement sensor capable of indicating strain with color emission and method of manufacturing the same

Provided are a torque transducer, a method for manufacturing the torque transducer, and a transmission for a vehicle using the torque transducer. The torque transducer includes a mechano-luminescent (ML) part disposed on a torque measuring object and an illumination sensor disposed to be spaced apart from the ML part.
