Hydrogel-based multi-stimuli responsive cilia

Glazer P.J., Leuven J., An H., Lemay S.G., Mendes E., Delft University of Technology, NL

We present large-scale multi-responsive cilia arrays that can be stimulated environmentally (via a pH change), electrically or magnetically. By means of micro-fabrication techniques, we created high-aspect ratio molds on which the polymer solution was cast. [...]

Control of MEMS-Technology Axial Topology MicroServos

Lyshevski S.E., Rochester Institute of Technology, US

Concurrent microsystems design, optimization, data-intensive analysis and hardware-software co-design of digital high-performance microelectromechanical systems (MEMS) have become major challenging themes. The major goal of this paper is to report-and-apply viable methodologies for design–and–implementation of MEMS [...]

Ultra High performance In-line Contact MEMS RF Switch

Hong Y-T, Kim C-H, Lee S-H., Kwon S-W, Song I-S, Samsung Advanced Institute of Technology, KR

An in-line direct RF MEMS Switch was presented in this paper. This switch having single contact point was fabricated, and characterized. The switch is a series type and is actuated by a supportive membrane. A [...]

Dynamic Simulation of an Electrostatically Actuated Impact Microactuator

Zhao X., Dankowicz H., Reddy C.K., Nayfeh A.H., Virginia Tech, US

We study the dynamics of an electrostatically driven impact microactuator reported by Mita and associates. The microactuator is modeled as a two-degree-of-freedom rigid multibody system. The impact phenomenon is described by a simple impact law [...]
