The erythrocyte membrane was defined as a hyperelastic material.
This material was described in terms of strain energy potential U, which defined the strain energy stored in the material per unit volume in the initial configuration as a function of the strain at that point in the material.
For homogeneous isotropic materials, the Young’s modulus E can be calculated using shear modulus G and Poisson’s ratio ν, E = 2G (1+ν) (4) Since we assume the membrane to be incompressible, the Poisson’s ratio ν should be ½.

Additionally, β-FeSi2 is made from abundant raw materials and has qualities of innoxious and anti-oxidative.
Therefore, β-FeSi2 is capable of developing thermoelectric materials which work at atmospheric conditions with low-cost and relatively wide temperature scope from 200℃ to 900℃ [1-4].
The raw materials were heated by high-frequency equipment under the protection of Ar atmosphere.
