Figure 2

Characterizing the mechanical and electrical performance of the twisted conductive microtubules. (a) Strain versus electrical resistance curve for microtubules with different amounts of twisting. (b) Optical image of the deformed cross section of a twisted microtubule pair (6 turns, 100% strain). (c) Optical images of the twisted microtubules with different turns in non-stretch (0%) and 100% strain conditions. (d) Change in resistance for twisted microtubule (18 turns, 230% nominal strain) under low amplitude (2%) cycling loading, illustrating the high sensitivity.
