Abstract
Ion exchange membrane-based sensors, actuators and sensor/actuators and methods of making same for applications requiring sensing, actuating and controlling displacement. Sensors, actuators, and sensor/actuators are useful in biological as well as other applications. Encapsulation of the sensors, actuators, or sensor/actuators further increases the utility of the present invention. Devices according to the present invention made using lithium are preferred over those made using only sodium.
