The substrate material utilized to simulate skin was silicone rubber (30A durometer high temp super-soft silicone rubber sheet, McMaster-Carr Inc., IL). Cyclic stretching involved adhering a 3 inch X 0.75 inch sample of polymeric sheet material onto a 9 inch X 3 inch silicone rubber strip. On two separate 9 inch X 3 inch silicon rubber strips, an individual first strip of the same polymeric material cut to 1.5 inch X 0.75 inch dimensions was applied, and an individual second strip of the same polymeric material cut to 1.5 inch X 0.75 inch dimensions was applied. The combined surface area of the two 1.5 inch X 0.75 inch strips was equivalent to the single 3 inch X 0.75 inch strip. The adhesives used in all instances described were identical. Each of the silicone strips, with adhered polymeric material, was secured only cylindrical holders attached to an MTS machine (MTS Systems Corp., Eden Prarie, MN) via double sided tape (0.75 inch double sided tape, Intertape Polymer Group Inc., Montreal, Canada), such that the free length of the silicone strip between the holders was 9 inches. MTS Systems Corp. is an industry leading testing and sensing solution company and a number of their products (including MTS model 569326-05, capacity 100N) were utilized in the work described in this section. The silicone strip, together with the adhered polymeric material, was then subjected to repeated tensile strain of 0 - 10% (10% X 9 inches = 0.9 inches of displacement) at 1 Hz frequency for 24 hours to simulate roughly two weeks of in vivo use. This was based on an assumption of approximately 2 million cycles of joint motion per year. Images of the samples were taken before and after testing to visually capture the extent of the adherence of the material following approximately 86,200 cycles (24 hours at 1Hz) of stretching. Following cyclic stretching, the silicone rubber substrate strips were fixed to an MTS machine base using double sided tape. Force was then applied to the polymeric material adhered to the silicone rubber strips, in the plane of application, until the polymeric material fractured. Table 1 below summarizes the peak and average forces recorded during the shear testing. The polymeric material used in the testing was coded 3604A, and was polyurethane (7 mil thickness).
