Actuators motion conversion

Friction and the changing mechanical advantage of these motion conversion mechanisms mean the available torque may vary greatly with travel. One notable exception is vane-style rotary actuators whose offset piston pivots, giving direct rotary output. 

The primary grouping of actuators by power source and range of motion permit some convenience in defining the actuator. The conversion of power to motion presents a large range of actuator designs. The different designs have distinctly different functional characteristics to consider... 

The energy conversion from light to mechanical response is one of the most fascinating targets in or nic photochromic systems. Section 15.2 already indicated the light-driven droplet displacement. This section introduces the motion of Az polymers themselves. Rapid motions observed here mi t allow for applications of actuators of polymer-based micromachine systems. The photoinduced surface-relief generation described in the latter part of this section (Section 15.4.2) deals with much thicker films than monolayers. Howevei the mass miration in thicker films is closely related to the structure and properties of the monolayer systems.
