Applications of the hair artificial muscles

Homochiral hair artificial muscles with the spring index of 8 and twist density of 2500 turns m-1 were used for weight lifting, pulling a model of car wheels under water, and sensitively switch off the light emitting diodes (LEDs) when exposed to water. The heterochiral hair muscles with the spring index of 15 and twist density of 2500 turns m-1 was used as a “sea cucumber” for climbing along a barbed cord under water.
