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...
متن کاملAnalysis 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.
متن کاملSurface Acoustic Waves to Drive Plant Transpiration
Emerging fields of research in electronic plants (e-plants) and agro-nanotechnology seek to create more advanced control of plants and their products. Electronic/nanotechnology plant systems strive to seamlessly monitor, harvest, or deliver chemical signals to sense or regulate plant physiology in a controlled manner. Since the plant vascular system (xylem/phloem) is the primary pathway used to...
متن کاملSurface Acoustic Wave Tactile Display
eveloping realistic tactile displays for virtual reality has been challenging. Tangible displays are increasingly important interfaces not only for augmenting the reality of computer graphics but also for conveying graphical information to persons with visual impairments. Researchers have used various actuators for displays such as miniature loud speakers , 1 a pin array, 2 pneumatic actuators,...
متن کاملApplications of Surface Acoustic and Shallow Bulk Acoustic Wave Devices
Applications of surface acoustic wave (SA W) and shallow bulk acoustic wave (SBA W) devices are reviewed. SA W-device coverage includes delay lines and filters operating at selected frequencies in the range from about 10 MHz to 11 GHz, modeling with singlecrystal piezoelectrics and layered structures, resonators and lowloss filters, comb filters and multiplexers, antenna duplexers, harmonic dev...
