Multi Contact Points Slider for A Surface Acoustic Wave Motor

Driving Characteristics of a Surface Acoustic Wave Motor using a Flat-Plane Slider

We discuss the use of a flat-plane slider for a surface acoustic wave (SAW) motor. For stable driving, the SAW motor requires a silicon slider with many microprojections on its surface. Previously, sliders with no projections on the flat-plane surface could not provide stable drive because of contact electrification occurring due to the low electrical conductivity of the lithium niobate stator....

Analysis of a Surface Acoustic Wave Motor

− Based on first principles a dynamical contact model of a Surface Acoustic Wave motor is built. Besides slider behavior also contact point behavior is obtained, which is hard to acquire experimentally. The contact point behavior is used to explain slider behavior like threshold amplitude and like oscillations that are observed in experimental set-ups.

Elastic friction drive of surface acoustic wave motor.

Importance of elastic deformation control to obtain large output force with a surface acoustic wave (SAW) motor is discussed in this paper. By adding pre-load to slider, stator and slider surfaces are deformed in a few tens nanometer. Appropriate deformation in normal direction against normal vibration displacement amplitude of SAW existed. By moderate deformation, the output force of the SAW m...

TiO2 based surface acoustic wave gas sensor with modified electrode dimensions for enhanced H2 sensing application

The design and optimization of nanostructure-based surface acoustic wave (SAW) gas sensor is analyzed based on TiO2 sensing layer and modified electrode dimensions. The sensitivity of the gas sensor depends upon the type of sensing layer used and active surface area obtained by varying the aspect ratio. The performance of the sensor is observed from 0.1ppm to 100ppm concentration of ...
