Abstract. In the field of microsystems, adhesion force between the two contact surfaces has an important contribution to the friction losses. Two adhesion models have been presented and compared with the classical Hertzian model: the Johnson–Kendall–Roberts (JKR) model and the Derjaguin-Muller-Toporov (DMT) model. Using the above adhesion mentioned models, friction coefficient in a micro balls linear system has been analytical investigated.
