Torsional electrostrictive actuators |
摘要 |
A torsional actuator includes a plurality of segments, each segment having a substantially rectangular shape. Each segment is comprised of an electroactive material that is poled along an elongated dimension of the rectangular shape. The segments are arranged side-by-side, with adjacent segments poled in opposing directions along their long dimensions. Conductors are positioned between adjacent sides of the side-by-side segments, with all of the juxtaposed segments being bound together in an integral structure. A power supply is connected to the conductors and applies oppositely poled electric fields across adjacent segments to cause like shear deformations of each of the segments and a resultant angular rotation of a non-fixed end thereof.
