  • Strain measurement sensor capable of indicating strain with color emission and method of manufacturing the same
    Patent number: 9983072
    Abstract: 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.
