Simple fabrication, high power-to-weight and power-to-volume ratios, and the ability to operate in open air at low voltage make the ionic electroactive polymer actuators highly attractive for haptic applications. Whenever a direct tactile stimulation of the skin is involved, electrical and chemical insulation as well as a long-term stability of...

We investigated three bulk fill composites (Mat1, Mat2, Mat3) cured by two polywave (Poly1, Poly2) and one monowave (Mono) lamps. We used infrared spectroscopy, nanoindentation and atomic force microscopy to assess degree of conversion (DC), stiffness, and roughness after polishing, respectively. Mat2 exhibited the highest DC with Poly1 and...

Bucky gel actuators are typically fabricated by having an electrolyte layer sandwiched by two carbon nanotubes electrodes. They possess outstanding electrical and mechanical properties thanks to their composition, which make them very attractive for robotics applications. Even though carbon nanotube electrodes have been extensively studied in...

A series of novel poly(ionic liquid)s/carbon nanotubes composites were prepared and studied. The effect of the anion on the thermal, mechanical and electrical properties of the composites was investigated. We obtained electrical conductivities ranged from 20 to 40 S cm-1 which are amongst the highest reported for a material involving poly(ionic...

Carbon nanotube actuators possess the requirements to be used in soft robotic applications as they are lightweight, simple to assemble and can operate at low voltage. However, there is still a need to further enhance their performances - in particular strain and blocking force - in order to render their implementation in devices more viable. In...

Bucky gel-based actuators represent one of the possible ways to exploit the outstanding electrical and mechanical properties of carbon nanotubes. Despite the continuous efforts to develop better devices, the lack of an accepted and simple way of characterizing the actuation mechanisms has often led to misestimate their performances. In this...

The long-term reliability of neural interfaces and stability of high-quality recordings are still unsolved issues in neuroscience research. High surface area PEDOT-PSS-CNT composites are able to greatly improve the performance of recording and stimulation for traditional intracortical metal microelectrodes by decreasing their impedance and...

Ethyl cellulose (EC)/polydimethylsiloxane (PDMS) composite films were prepared at various concentrations of PDMS in the films (0, 5, 10, 15, and 20 wt.%). Morphological and chemical analysis by EDX-SEM and ATR-FTIR showed that EC-rich matrices and PDMS-rich particles were formed, with the two polymers interacting through H–bonds. The number and...
