文摘

Ex vivo skin showed similar friction values as those obtained in previous research at both, dry and wet condition. The theoretical coefficient of friction given by the JKR model agrees with the experimental data at dry conditions. Capillary adhesion included in the JKR model causes an increase of the theoretical coefficient of friction at low forces. Other mechanisms must be considered to achieve the large coefficient of friction of skin at low forces and wet conditions.
