Abstract: Methods and computer-readable mediums are provide that, in some embodiments maximize bending of an actuator and, in other embodiments, minimize bending of the actuator. For example, in one embodiment, a method is provided that acquires a first ratio of a modulus of inertia for a first component to a Young's Modulus for the first component. The method also acquires a second ratio of a modulus of inertia for a second component to a Young's Modulus for the second component. Thereafter, the method provides an actuator (which includes the first component and second component). The actuator has a cross-sectional shape such that the first ratio substantially equal to said second ratio. In various embodiments of the invention, the actuator is spun fibers formed into batting and used as insulation, or may form an active element of a thermostat.

Abstract: Methods and computer-readable mediums are provide that, in some embodiments maximize bending of an actuator and, in other embodiments, minimize bending of the actuator. For example, in one embodiment, a method is provided that designs and determines a Ratio1 for a first component. Ratio1 is a modulus of inertia for the first component divided by a Young's Modulus for the first component. Thereafter, a second component is designed that has a Ratio2 substantially equal to the Ratio1 of the first component. Ratio2 is a modulus of inertia for the second component divided by a Young's Modulus for the second component. Thereafter, the first component and the second component can be used to make an actuator that is spun into fiber to make products (e.g., batting material, woven material, a suture, a thermostat needle, a gel, etc.). Other embodiments are provided that utilize computer-readable medium.
