Experimental results Different sensors based on three kinds of materials are tested respectively, the results is shown in Figure 3, where material 1 stands for NBR, material 2 stands for HDPSF and material 3 represents PTFE.
Experimental results of three kinds of materials Under the condition that the microbending degrees are in same level, the greater the elastic modulus of a gasket is, the wider the range of the sensor measurement can be achieved accordingly.

Introduction Semiconducting silicides are promising materials due to their compatibility with silicon technology.
Compared with other semiconducting materials such as GaAs and InP, Mg2Si is an ecologically friendly semiconducting material because its constituent elements are non-toxic and abundant in the earth’s crust [1].
