Abstract: , the adhesion force increases by ∼10% with respect to the lowest measured velocity. This indicates that the system can intriguingly exhibit a counterclockwise hysteretic force loop in which a greater amount of energy can be generated once the retraction velocity is set above the protraction velocity, which is explained by utilizing the available thermal energy to reduce adhesion. The ability to realize mesoscopic mechanical systems that can conceptually extract useful mechanical energy by thermal fluctuations can potentially lead to disruptive technologies such as artificial surfaces, in which controlled motion of elements is manifested by manipulated Brownian motion and self-powered actuators with energy harvest capabilities.
