In this study, the flexoelectric and piezoelectric distributed sensing signal of toroidal shell is discussed. By considering curvature radii Lamé parameters shell, dynamic strains are derived based on double-curvature shell. Flexoelectric models established. Based direct effect effect, flexoelectric/piezoelectric evaluated respectively. The local neural discussed while sensor patches approach t...
