ISR intellectual property available to license
U.S. Patent: 7,523,608
The present invention exploits the above phenomena. An actuation apparatus and a method utilizing electroosmotic pumping for generating stresses and strains that are capable of exceeding those generated by conventional actuators is proposed. The actuator is applicable in a variety of fields, such as mechanics, aerodynamics, etc., and a host of additional fields that utilize stress and/or strain actuators and an actuation apparatus and method which is robust in design and is relatively simple and economical to manufacture and implement.
Generally, the present invention provides an actuator cell and an actuator plate utilizing that can exhibit both large stresses in the tens of mega-Pascals and large strains of 30% or more, by embedding micro-fluidic networks consisting of channels and expanding chambers and compliant electrodes inside bonded layers of flexible material.
