Multi-size adaptability and mechanical characterization. (A–D) The MSC-16 cuff adapts to metal rods of different diameters (100–1000 µm). SMP cuffs implanted snugly onto nerves of different diameters: (E) PN (200 µm), (F) vagus nerve (600 µm), (G) CPN (800 µm), and (H) ScN (1000 µm). Arrowheads in (E–H) point to the sutures used as cuff closing mechanism. (I) Dynamic mechanical analysis shows the SMP storage modulus over time in PBS at 37 °C. (J) Storage modulus (solid lines) and tan δ (dashed lines) of the SMP before (dry, orange lines) and after soaking in PBS for 1 h (blue lines). Dotted line in J correlates with the values at physiological temperature, 37 °C.
