(A) The shaker (on the left) was attached to an accelerometer that was directly glued to the samples. The accelerator used to measure the output was glued to the other end of the sample. The acrylic braces (red) were used to hold the soft architecture at well-defined widths and were glued to the laboratory stands to prevent unwanted movement. (B) Small-amplitude, linear excitation from either end of the chain is rapidly dissipated due to the damping intrinsic to the polymer, as is particularly evident with increasing frequency, shown here for samples with 6, 15, and 50 bistable units.
