A Superlubricated Magnetically Steerable Microcatheter with Integrated Optical and Fluidic Channels

Advanced Robotics Research, EarlyView.
A magnetically steerable microcatheter with integrated optical and fluidic channels is developed for multifunctional navigation in tortuous anatomical environments. A surface‐grafted hydrogel coating enables low‐friction actuation. The device demonstrates stable light and fluid delivery during magnetic manipulation, offering a compact platform for ...

Dynamic Deflection of Electrostatic MEMS

2005 International Conference on MEMS,NANO and Smart Systems, 2006
An idealized electrostatic MEMS device, consisting of a thin dielectric elastic membrane supported above a rigid ground plate, is analyzed. The upper surface of the membrane is coated with a thin conducting film. When a voltage V is applied to the thin conducting film, the membrane deflects towards the ground plate and if V is increased beyond a ...

Dynamic Pavement Deflections

Transportation Engineering Journal of ASCE, 1981
In 1977 a methodology was developed to evaluate pavement performance using dynamic (Road Rater) deflections. Since then, additional research has resulted in modifying the procedures. The procedures presently used to evaluate flexible pavement structures are explored, and background information is included on various procedures used by others.

Capacitance Microphone Dynamic Membrane Deflections

The Journal of the Acoustical Society of America, 1972
In order to describe the operation of capacitance microphones accurately, it is necessary to have solutions for both the static and dynamic deflections of the moving electrode. The authors have previously presented numerical solution approaches to the static deflections caused by the electrical biasing of the microphone.
