The control of a flexible beam using ionic polymer metal composites (IPMCs) is investigated in this paper. mechanical dynamics are modelled as Timoshenko beam. electric the IPMCs considered model. port-Hamiltonian framework used to propose an interconnected model and IPMC actuator. Furthermore, passive Hamiltonian structure-preserving linear quadratic Gaussian (LQG) controller achieve desired c...

This paper discusses a number of recent findings in connection with ion-exchange polymer-noble metal composites (IPMC) as biomimetic sensors and actuators. These smart composites exhibit characteristics of both actuators and sensors. Strips of these composites can undergo large bending and flapping displacement if an electric field is imposed across their thickness. Thus, in this sense they are...

Abstract Ionic polymer metal composites (IPMCs) are a class of materials with rising appeal in biological micro-electromechanical systems (bio-MEMS) due to their unique properties (low voltage output, bio-compatibility, affinity ionic medium). While tailoring and improving actuation capabilities IPMCs is key motivator almost all IPMC manufacturing reports, very little efforts have been dedicate...

An ionic polymer-metal composite (IPMC) consisting of a thin perfluorinated ionomer (usually, Nafion or Flemion) strip, platinum and/or gold plated on both faces, undergoes large bending motion when a small electric field is applied across its thickness. When the same membrane is suddenly bent, a small electric potential of the order of millivolts is produced across its surfaces. This actuation...

Many intraductal papillary mucinous neoplasms (IPMNs) are asymptomatic and discovered incidentally during medical checkups follow-up of other diseases. There various stages IPMN from benign to malignant, but it is a risk factor for pancreatic cancer in the sense that associated with IPMC-derived invasive carcinoma developing as complication. occurs more often elderly patients, does not lead sur...

Ionic polymer-metal composites (IPMCs) consist of a perfluorinated ionomer membrane (usually Nafion or Flemion). The ionomer is plated on both faces with a noble metal such as gold or platinum. It is neutralized with a certain amount of counterions that balance the electrical charge of anions covalently fixed to the backbone membrane. IPMCs are electroactive materials that can be used as actuat...
