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 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 کاملTailoring the actuation of ionic polymer–metal composites
Ionic polymer–metal composites (IPMCs) are biomimetic actuators and sensors. A typical IPMC consists of a thin perfluorinated ionomer membrane, with noble metal electrodes plated on both faces, and neutralized with the necessary amount of cations. A cantilevered strip of IPMC responds to an electric stimulus by generating large bending motions and, conversely, produces an electric potential upo...
متن کاملTailoring actuation of ionic polymer-metal composites through cation combination
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...
