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...
متن کاملPassive Downhole Pressure Sensor Based on Surface Acoustic Wave Technology
A passive surface acoustic wave (SAW) pressure sensor was developed for real-time pressure monitoring in downhole application. The passive pressure sensor consists of a SAW resonator, which is attached to a circular metal diaphragm used as a pressure transducer. While the membrane deflects as a function of pressure applied, the frequency response changes due to the variation of the SAW propagat...
متن کاملSensors - Acoustic Wave Technology Sensors
Acoustic wave devices have been in commercial use for more than 60 years. The telecommunications industry is the largest consumer, accounting for ~3 bil lion acoustic wave filters annually, primarily in mobile cell phones and base stations. These are typically surface acoustic wave (SAW) devices, and act as bandpass filters in both the radio frequency and intermediate frequency sections of the ...
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 کاملSurface Acoustic Wave Based Magnetic Sensors
Since the radar system was invented in 1922, the development of devices communicating by means of reflected power has experienced a continuously growing interest. In 1948, Harry Stockman published a paper [1] in which he laid the basis for the idea of radio frequency identification (RFID), and the first patent had been filed in 1973 by Charles Walton. After decades of research and commercializa...
