Abstract
Official abstract text for this publication.
A hinge-type actuator device in accordance with the present disclosure may include a first and second paddle, a first and second artificial muscle actuator segment, and a plurality of contacts, where the first and second artificial muscle actuator segments are actuated via the contacts, actuation of the first artificial muscle actuator segment causes the first and second paddle to open the hinge-type actuator, and actuation of the second artificial muscle actuator segment causes the first and second paddle to close the hinge-type actuator.
First claim
Opening claim text (preview).
What is claimed is: 1. A linear displacement device comprising: a first artificial muscle actuator and a second artificial muscle actuator; and a body that is restricted to move linearly, the body having a first surface and a second surface that opposes the first surface; wherein the first artificial muscle actuator and the second artificial muscle actuator are configured to cause the body to move linearly, the first artificial muscle actuator expanding when actuated, thereby causing the body to move in a linear direction away from a base, the second artificial muscle actuator contracting when actuated, thereby causing the body to move in the linear direction towards the base, wherein a first end of each of the first artificial muscle actuator and the second artificial muscle actuator is attached to a same surface of the base, and a second end of each of the first artificial muscle actuator and the second artificial muscle actuator is attached to the second surface of the body, and wherein both the first artificial muscle actuator and the second artificial muscle actuator extend between the same surface of the base and the second surface of the body. 2. The linear displacement device of claim 1 , further comprising: a latch provided facing the first surface of the body and holding the linear displacement device in a first position, wherein the linear displacement device is configured to move towards a second position when an external force is applied to at least one of the first artificial muscle actuator and the second artificial muscle actuator. 3. The linear displacement device of claim 1 , wherein: the first muscle actuator is a heterochiral artificial muscle actuator, and the second muscle actuator is a homochiral artificial muscle actuator.
