Observation of the toe pad structure shows that shorter setae are generally proximal while longer ones distal [39]. We hypothesized that a seta of longer length would generate higher adhesive force, as long and slender setae have lower bending modulus, and therefore making it easier to contact spatulae with the surface. By following previous single seta experiments [11], we first measured the shear force generated by an isolated gecko seta using Nano Bionix. We also tested the length hypothesis by measuring the shear adhesion ability of single seta of varying lengths ranging from 80 to 140µm, which was taken from different parts of the gecko toe pad from distal to proximal. Measurements gave the result of shear forces of a single seta in the range of 80 to 250µN and an average of 136.81µN. This number is lower than the average value 194µN in previous studies, which is tested under a preload of 15µN [11]. In addition, results from 12 individual setae suggested that shear adhesion force of a single seta is independent of setal length and dependent on setal diameter. 2018-06-08 English text University of Akron / OhioLINK http://rave.ohiolink.edu/etdc/view?acc_num=akron1523202746417773 http://rave.ohiolink.edu/etdc/view?acc_num=akron1523202746417773 unrestricted This thesis or dissertation is protected by copyright: all rights reserved.
