Modeling and Fabrication of Ionic Polymer-metal Composite (ipmc) Sensors

MODELING AND FABRICATION OF IONIC POLYMER-METAL COMPOSITE (IPMC) SENSORS By Hong Lei Ionic polymer-metal composites (IPMCs) are an important class of electroactive polymers (EAPs) with built-in actuation and sensing capabilities. They have received tremendous interest for their potential in various sensor applications. In this dissertation, a physics-based dynamic model is proposed for cantilev...

Quasi-static Positioning of Ionic Polymer-Metal Composite (IPMC) Actuators

Ionic polymer-metal composites (IPMCs) generate large bending motions under a low driving voltage (about 1 V). In this paper quasi-static actuation of IPMC is investigated with the goal of precise positioning. It is found that IPMC exhibits hysteresis between its bending curvature and the applied quasi-static voltage. The Preisach operator is proposed to model the hysteresis, and its density fu...

Self-Sensing Control of Nafion-Based Ionic Polymer-Metal Composite (IPMC) Actuator in the Extremely Low Humidity Environment

This paper presents feedforward, feedback and two-degree-of-freedom control applied to an Ionic Polymer-Metal Composite (IPMC) actuator. It presents a high potential for development of miniature robots and biomedical devices and artificial muscles. We have reported in the last few years that dehydration treatment improves the electrical controllability of bending in Selemion CMV-based IPMCs. We...

Fabrication of ionic-polymer-metal-composite (IPMC) micropump using a commercial Nafion

This paper describes the fabrication and characteristics of an ionic polymer-metal composite (IPMC) membrane-shaped micro-actuator and its application to the fabrication of a micro-pump. After fabricating two 8mm×8mm IPMC membraneshaped actuators using a Nafion film, their displacements were measured. The fabricated IPMC membrane-shaped micro-actuators showed displacement of 14∼27μm at the appl...
