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. In another embodiment, a device includes a base flexibly coupled to an oscillation bridge. The device further includes a polymer actuator that includes a first end coupled to the base and a second end coupled to the oscillation bridge. A voltage applied to the polymer actuator translates the oscillation bridge with respect to the base such that the oscillation bridge linearly travels parallel to the base.
