Vibration analysis and pull-in instability behavior in a multiwalled piezoelectric nanosensor with fluid flow conveyance

Beilstein Journal of Nanotechnology, 2020
In this work, surface/interface effects for pull-in voltage and viscous fluid velocity effects on the dimensionless natural frequency of fluid-conveying multiwalled piezoelectric nanosensors (FC-MWPENSs) based on cylindrical nanoshells is investigated ...

Dual Excitation Electrostatic Stepping Motor.

IEEJ Transactions on Industry Applications, 1996
Electrostatic motors have been believed to be weaker than electromagnetic motors which are typically used for mechatronic devices. However, electrostatic motors are preferable to electromagnetic ones for micro mechanical applications since their force per volume ratios increase as their dimensions are reduced. This follows that a large output should be

Excitation of twin-vortex flow in the nightside high-latitude ionosphere during an isolated substorm [PDF]

, 2002
We present SuperDARN radar observations of the ionospheric flow during a well-observed high-latitude substorm which occurred during steady northward IMF conditions on 2 December 1999.

Electrostatically actuated encased cantilevers

Beilstein Journal of Nanotechnology, 2018
Background: Encased cantilevers are novel force sensors that overcome major limitations of liquid scanning probe microscopy. By trapping air inside an encasement around the cantilever, they provide low damping and maintain high resonance frequencies for ...

Computer simulations for direct conversion of the HF electromagnetic wave into the upper hybrid wave in ionospheric heating experiments [PDF]

Annales Geophysicae, 1998
Excitation of upper hybrid waves associated with the ionospheric heating experiments is assumed to be essential in explaining some of the features of stimulated electromagnetic emissions (SEE).
