Fig. 3: Quantitative analysis of the traction forces and wrinkles.

a Probability distribution function (PDF) of the traction magnitude. b The wrinkle length as the function of the mean traction \(\bar{f}\). Note that the wrinkle length is evaluated by counting the number of pixels after skeletonizing the wrinkle images. c The wrinkle length as the function of the principal traction fp. d Probability distribution function of the angle differences between the wrinkle direction Ï•w and the traction Ï•s. The figure suggests that the direction of the wrinkles is predominantly perpendicular to the principal direction of the force.
