We review some patents on the use of Ionic Polymer-Metal Composites (IPMCs) and its manipulation to be used by different application areas. The different IPMC structures patented the techniques to improve its efficiency, and their operation as sensor and/or actuator mode. Some advantages/disadvantages of the different structures presented in relation to other existing but not using the IPMC material are also pointed out. Some future perspectives for the application of IPMCs are also explored.
