compliance of the tip. Here, we mimic this feature using tilted, mushroom-like, stiff fibers comprised of a stiff stalk of elastic modulus 126 MPa, a softer tip of elastic modulus 8.89 MPa, and a joint-likeelement of elastic modulus 0.45 MPa (very soft), 8.89 MPa (soft), or 126 MPa (stiff) in between. The

Most natural organisms that rely on temporary adhesion to surfaces for survival do so using tiny, densely packed fibers [1][2]. These fibers vary in dimension and material properties
, termed as a joint-likeelement, is evidenced by the difference in color of this joint from the stalk or the tip (see Figure 1a). The joint-likeelement is believed to be more flexible and equips the fibers with the necessary articulation to better adapt to the target surface [32]. This joint can consist

structures connecting claws and pulvilli to the terminal tarsomere [43][50]. In the pretarsus of the drone fly (Eristalis tenax) (Insecta, Diptera, Syrphidae), for example, membranous cuticle with large proportions of resilin forms a spring-like (or joint-like) element (Figure 3A–C) that makes the pulvilli
