① Calculate k_cant

Nominal spring constant k_nom

Nominal frequency f_nom (kHz)

Measured cantilever frequency f_cant (kHz)

② Calculate Deflection & Force

FT Voltage — F_T (V)

FN Voltage — F_N (V)

📖 Formulas

k_cant = k_nom × (f_cant / f_nom)³

Deflection (nm) = (F_N × 1000) / (11.937 × F_T − 7.464)

Force (nN) = Deflection × k_cant
