Plant-based torsional actuator with memory

A bundle of a few loblolly pine (Pinus taeda) cells are moisture-activated torsional actuators that twist multiple revolutions per cm length in direct proportion to moisture content. The bundles generate 10 N m kg−1 specific torque during both twisting and untwisting, which is higher than an electri...
