摘      要：Surface tension plays a central role in the mechanical behavior of soft materials such as *** deformation of elastic graded substrates is ubiquitous in soft *** this work,the effect of a partially wetting sessile liquid droplet on the elastocapillary deformation of a soft elastic graded substrate is *** modulus is assumed to have an exponential form along the thickness *** applying the Fourier transformation,a mixed boundary-value problem is reduced into a dual integral *** numerical results show that the surface displacement is strongly affected by the inhomogeneity of the *** study of the wetting properties of gel substrates is essential for both understanding the wetting phenomena of gels and developing gels for applications as soft actuators and sensors that can be used in wearable electronics and soft robotics.
