Acoustic Electric Generation for Morlet Wavelet Transform of Surface Acoustic Wave Device

Manufacturing error correction model of the wavelet transform processor using surface acoustic wave devices

The goal of this study was to investigate the manufacturing error correction model of the wavelet transform processor (WTP) using surface acoustic wave (SAW) devices. The motive of this work was prompted by the output accuracy of the WTP using SAW devices varying with the manufacturing accuracy of each finger of the devices. Thus, in this paper, we presented the functional relationship between ...

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 ...

Surface 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,...

Applications 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...
