We consider the problem of attitude stabilization for a low Earth orbit satellite having only electromagnetic actuation. Such is not fully actuated, as control torque cross-product magnetic moment due to magnetorquers and geomagnetic field. The aim this work study whether oscillating controls can be designed such that actuated via alone achieve full three-axis irrespective position satellite. T...

Medical microrobots have been widely used in clinical applications, particularly the spiral type locomotion mechanism, which was recently considered one of the main self-propelling mechanisms for the next medical microrobot to perform tasks such as capsule endoscopy and drug delivery. However, limits in clinical applications still exist. The spiral action of the microrobot while being used for ...

Miniaturized fluid manipulation systems are an important component of lab-on-a-chip platforms implemented in resourced-limited environments and point-of-care applications. This work aims to design, fabricate, test a low-cost battery-operated microfluidic diffuser/nozzle type pump enable alternative solution for field For this, CNC laser cutting 3D printing used fabricate the fluidic unit casing...

In the current study, the effects of Casimir force and squeeze film damping on pull-in instability and dynamic behavior of electrostatically actuated nano and micro electromechanical systems are investigated separately. Linear elastic membrane theory is used to model the static and dynamic behavior of the system for strip, annular and disk geometries. Squeeze film damping is modeled using nonli...
