  Particle resuspension is a ubiquitous phenomenon with pivotal relevance in
numerous natural and industrial contexts. In this study, we present findings on
the resuspension of individual micro-sized particles, captured through
high-speed camera experiments. Our observations reveal a universal behavior
whereby a particle undergoes oscillatory motion due to turbulent excitation
prior to its detachment from the surface. This motion is characterized by
dimensionless number Ad and S. The frequency of particles oscillation is
analyzed and it shows the frequency of particle oscillations increased with
decreasing particle size. We establish a new model that the particle is a
linear oscillator driven by stochastic torque from turbulence. It is shown that
the stochastic oscillation is the key mechanism for particle detachment from a
wall within a certain range of friction velocities.
