Control of Ionic Polymer Metal Composites
Robotic devices are traditionally actuated by hydraulic systems or electric motors. However, with the desire to make robotic systems more compact and versatile, new actuator technologies are required. In this paper, the control of ionic polymer metal composite actuators is investigated from a practical perspective. The actuator characteristics are examined though the unblocked maximum displacem...
متن کاملElectromechanical response of ionic polymer-metal composites
An ionic polymer-metal composite ~IPMC! consisting of a thin Nafion sheet, platinum plated on both faces, undergoes large bending motion when an electric field is applied across its thickness. Conversely, a voltage is produced across its faces when it is suddenly bent. A micromechanical model is developed which accounts for the coupled ion transport, electric field, and elastic deformation to p...
متن کاملMicrovalves based on ionic polymer-metal composites for microfluidic application.
Simple and highly efficient microvalve systems based on an ionic polymer-metal composite (IPMC) diaphragm actuator have been developed. The microvalve system that was fabricated in this work operates when open and close voltage is applied, due to the phenomena of lithium ion flux and the subsequent electro-osmotic drag of water to the cathode. IPMC was prepared by compositing with platinum nano...
متن کاملMicromechanics of actuation of ionic polymer-metal composites
Ionic polymer-metal composites ~IPMCs! consist of a polyelectrolyte membrane ~usually, Nafion or Flemion! plated on both faces by a noble metal, and is neutralized with certain counter ions that balance the electrical charge of the anions covalently fixed to the backbone membrane. In the hydrated state ~or in the presence of other suitable solvents!, the composite is a soft actuator and sensor....
متن کاملIonic Polymer-Metal Composites (IPMC) As Biomimetic Sensors and Actuators
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...
