Abstract
A flat motor. The flat motor comprises a substrate, a cantilevered, resilient lever arm mounted, by a passive end, on the substrate; and a shape-memory transducer acting on the lever arm wherein movement of the transducer deflects the lever arm.
Claims11
A flat motor comprising:
- a substrate;
- a cantilevered lever arm mounted, by a first end, on the substrate;
- and
- a shape-memory transducer acting on the cantilevered lever arm wherein movement of the transducer deflects the cantilevered lever arm.

A motor comprising:
- a substrate;
- a cantilevered lever arm mounted, by a first end, on the substrate;
- a shape-memory transducer acting on the cantilevered lever arm wherein movement of the transducer deflects the cantilevered lever arm;
- a latch;
- and
- second end of the cantilevered lever arm which engages the latch to thereby release the latch when the transducer is activated.
3 more elements
A motor comprising:
- a substrate;
- a cantilevered lever arm mounted, by a first end, on the substrate;
- a shape-memory transducer acting on the cantilevered lever arm wherein movement of the transducer deflects the cantilevered lever arm;
- an electrically conductive strip attached to the substrate;
- a plurality of electrically conductive elements attached to the substrate adjacent to the strip;
- and
- a wiper arm attached to the crank wherein the wiper arm bridges the strip and the elements to complete an electrical circuit with the shape-memory transducer to thereby move the crank to a preselected position.
