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.
