Modeling hysteresis and creep characteristics of a carbon-nanotube-reinforced electroactive actuator

Sohn K., Shin S.R., Yi B-J, Kim S.I., Kim S.J., Kim S.I., Kim S.J., Hanyang University, KR

For smart materials that are useful in wide variety of applications such as microelectromechanical systems (MEMS), machine components, and artificial muscle, the nonlinear phenomena of hysteresis and creep are essential consideration. We investigated movement of [...]

IDEA, a CAD Tool for the Design of Deformable Micro-Structures: Extension to the 2D Deformation of Arbitrarily-Shaped Membranes

Juillard J., Colinet E., SUPELEC, FR

A method for solving design problems involving coupled-field physics is presented: it is demonstrated in the case of the electrostatic actuation of a deformable micro-mirror. The focus of the present paper is on the inversion [...]

Modeling the Fluid Dynamics of Electro-Wetting on Dielectric (EWOD)

Walker S., Shapiro B., University of Maryland, US

By applying voltages across a liquid droplet and an underlying dielectric, it is possible to make dielectric forces compete with surface tension forces, and to thereby cause the liquid droplet to change shape. This effect [...]

A Neural-Network-Based-Method on Speed Control of Ultrasonic Motors

Liang Y.C., Shi X.H., Lee H.P., Lee K.H., Lin W.Z., Xu X., Lim S.P., Lee H.P., Lee K.H., Jilin University, CN

An improved Elman network models, output-input feedback (OIF) Elman networks is proposed based on the modified Elman network. A neural-network-based iteration control system (NNICS)) is developed by using the OIF Elman network as a passageway [...]
