Design and Simulation of Strain Sensitive Metamaterial

This paper proposes a highly sensitive metamaterial intended for strain sensing. The proposed metamaterial is suitable for strain sensing because it has advantages of easy stretching and TPU substrate expansion, making it possible to observe different absorption peak frequencies under different strains. Numerical simulations show that the peak absorption frequency of the sensor varies from 107.9 GHz to 118.5 GHz as the tensile force along x-axis increases from 0 to 4.06 N.
