Theoretical modeling demonstrates electromechanical deflection formulas for quartered piezoelectric tubes, highlighting precise calibration methods for scanning probe microscopes.

Key Points

Derive an analytical formula for the electromechanical deflection of piezoelectric tubes with sectioned quadrant electrodes under applied voltage.
Formulated an analytical equation relating applied quadrant voltage, tube geometry (length, diameter, wall thickness), and piezoelectric coefficient (d31) to transverse deflection.
Evaluated the analytical model against finite-element calculations and direct experimental deflection measurements.
Derived the electromechanical deflection equation as (√2 d31 V L^2)/(π D h) when a voltage V is applied across a single electrode quadrant.
Achieved consistent agreement between theoretical predictions, numerical finite-element calculations, and direct experimental data.
