Abstract:We propose a simple methodology to paint carbon nanotube (CNT) powder with a soft brush onto an elastomer. A large deformation of dielectric elastomer actuator (DEA) occurs according to the small constraint of the electrodes. Uniform painting with a soft brush leads to a stable deformation, as demonstrated by the results of multiple trials. Unexpectedly, painting with a soft brush results in aligned materials on the elastomer. The oriented materials demonstrate anisotropic mechanical and electronic properties. This simple methodology should help realize innovative DEA applications.

In this study, the propagation phenomena of phase differences under 180 degrees between adjacent oscillators can be observed on coupled oscillators by inductors as a lattice. The phenomenon can be observed in transient states. We call the phenomenon "phase-waves." We explain the propagation and the reflection mechanisms of the phase-waves using frequencies of each oscillator and phase differences between adjacent oscillators. Furthermore, we discover to observe an other wave on the above same circuit. The wave can be observed in steady states. We call the wave "phase-inversion wave." We clarify a region which can be observed the phase-inversion waves.
