WebSep 13, 2013 · The braid bias angle and muscle chirality can be selected so that pores either open or close during heating. Using novel textile weaves, comfort-adjusting clothing might be created by combining polymer muscles having large thermal contractions (up to 1.2%/°C, Fig. 4C) with those that thermally expand, to thereby amplify textile porosity changes.
