Normal Stiffness Calibration Of Microfabricated Tri-Layer Conducting Polymer Actuators, Michael J. Higgins, Gursel Alici
Normal Stiffness Calibration Of Microfabricated Tri-Layer Conducting Polymer Actuators, Michael J. Higgins, Gursel Alici

This paper reports on the stiffness characterization of microfabricated tri-layer conducting polymer (PPy) actuators. The rectangular, polypyrrole microactuators, which could operate both in aqueous and non-aqueous media, were fabricated using an excimer laser ablation technique that provided high throughput production and did not require cleanroom facilities. The microactuators were fixed at one end with electrical contacts and the other was end free to act as an electroactive microcantilever beam. An atomic force microscope (AFM) was used to measure the microactuator deflection under a range of normal forces applied by the AFM cantilever. A modified reference spring constant calibration method was …

The controlled deposition of polyaniline carbon nanotube composites by inkjet printing is reported. It is demonstrated that the sheet resistance and transmittance can be expressed in amount of composite and MWNT material deposited. The most efficient way for improving the sheet resistance while keeping the cost in optical transparency to a minimum is by increasing the total amount of material deposited, rather than increasing MWNT loading fraction.

The inkjet processing of water dispersable polymer carbon nanotube composite materials is reported. Single printed layers displayed good optical transparency, sheet resistance, and conductivity. It is demonstrated that an alcohol sensor based on a single printed layer of polymer carbon nanotube composite could operate at a lower voltage compared to a sensor based on a single printed layer of the polymer.

Electroactive polymers can be engineered at the molecular level to recognise external stimuli, they are conductive and they are capable of localised processing. These are properties which make them ideal building blocks for intelligent materials. This article investigates the suitability of carbon nanotubes of enhancing (polymer) building blocks for intelligent materials.
