Macro Fiber Composite (MFC) is extensively utilized in aviation, aerospace, civilian, and military domains owing to its high piezoelectricity, flexibility, minimal loss. Nevertheless, contemporary research on MFC sensors has predominantly focused material applications, with a conspicuous lack of systematic investigation into the simulation modeling sensor devices. In this study, three models—namely, Representative Volume Element (RVE) model, Direct Hybrid model—have been introduced analyze finite element models MFC, encompassing scales ranging from microscopic macroscopic.<br>On one hand, equivalent RVE model facilitates an understanding internal electric field distribution within thereby establishing theoretical foundation for force-electric coupling. On other application aligns boundary conditions laying groundwork stress sensing resonance mechanisms MFC. These constitute effective tools predicting performance smart sensors. The outcomes indicate that resonant exhibit significantly superior compared patch Under where excitation acceleration 5 m/s² cantilever substrate length 80 mm, simulated frequency 67 Hz, output voltage 4.17 V. Experimental results corroborate these findings, reporting 74 Hz 3.59 V sensor. notable consistency between experimental worth highlighting.
