Linear electro-polymer motors and devices having the same |
| 摘要 |
A linear electro-polymer motor includes a fixed member, a linear shaft having an axis, a polymer actuator, and a bias member. The polymer actuator includes a first end fixedly connected to the linear shaft and a second end fixedly connected to the fixed member. The bias member includes a first end fixedly connected to the linear shaft and a second end fixedly connected to the fixed member. The polymer actuator changes length after receipt of voltage to linearly move the linear shaft along the axis. |

1. A linear electro-polymer motor comprising:
a fixed member; a linear shaft having an axis associated therewith; a polymer actuator comprising a first end and a second end, wherein the first end of the polymer actuator is fixedly connected to the linear shaft and the second end of the polymer actuator is fixedly connected to the fixed member; and a bias member comprising a first end and a second end, wherein:
the first end of the bias member is fixedly connected to the linear shaft;the second end of the bias member is fixedly connected to the fixed member such that a spring force provided by the bias member opposes a movement of the linear shaft provided by the polymer actuator; andthe polymer actuator changes length after receipt of voltage to move the linear shaft along the axis,wherein the bias member comprises a second polymer actuator. |
