viscoelastic elements and prescribing a harmonic law of motion for the sphere, the model successfully reproduces the vibration-induced contact and detachment phenomena observed in tunable adhesive systems. Future activities will focus on a systematic investigation of the influence of excitation frequency and material parameters, numerical validation through finite element simulations, and experimental verification of the predicted behavior. Finally, it is expected to use the obtained and future results to investigate the durability of the involved materials, with aim of optimizing the adhesion tunability and broaden the applicability of the proposed approach in soft robotic interfaces.
