Abstract

This study investigated the forces and the cross-section images of a water strider's leg through experimental observations. In the vertical direction, the spring coefficients were found to be 0.6 N/m for the leg and 0.3 N/m for the water, which provide a water-treading stiffness of 0.2 N/m. In the horizontal directions, besides the alignment of the microsetae, the large cuticle forces were also related to the resistant side in a Wenzel state.
