A Study on RF Signal Generator and Analyzer for Passive Surface Acoustic Wave based Wireless Sensors
نویسندگان
چکیده
Sensor technologies are rapidly growing and wireless measurement systems with passive surface acoustic wave (SAW) sensors are broadly used in wide variety of sensor applications. To developing and validating batter-less wireless sensors, generally frequency characteristic of the sensor is analyzed by using an oscilloscope. However, the oscilloscope based system only analyzes simple waveforms. Thus, we propose and develop a new SAW system analyzer and a SAW reader emulator for emulating the RF signals. Finally, we show the better performance of our approach.

An Improved Performance Frequency Estimation Algorithm for Passive Wireless SAW Resonant Sensors
Passive wireless surface acoustic wave (SAW) resonant sensors are suitable for applications in harsh environments. The traditional SAW resonant sensor system requires, however, Fourier transformation (FT) which has a resolution restriction and decreases the accuracy. In order to improve the accuracy and resolution of the measurement, the singular value decomposition (SVD)-based frequency estima...
متن کاملThree Dimensional Localization of an Unknown Target Using Two Heterogeneous Sensors
Heterogeneous wireless sensor networks consist of some different types of sensor nodes deployed in a particular area. Different sensor types can measure different quantity of a source and using the combination of different measurement techniques, the minimum number of necessary sensors is reduced in localization problems. In this paper, we focus on the single source localization in a heterogene...
متن کاملAcoustic Transducers as Passive Cooperative Targets for Wireless Sensing of the Sub-Surface World: Challenges of Probing with Ground Penetrating RADAR
Passive wireless transducers are used as sensors, probed by a RADAR system. A simple way to separate the returning signal from the clutter is to delay the response, so that the clutter decays before the echoes are received. This can be achieved by introducing a fixed delay in the sensor design. Acoustic wave transducers are ideally suited as cooperative targets for passive, wireless sensing. Th...

Wirelessly interrogated surface acoustic wave (SAW) sensors can operate passively and in harsh conditions reliably. The interrogation process of the signal measurement chain provides the power to excite the sensor and hence establish the sensors response in a passive manner. Development of wireless passive SAW sensors allows investigation of their potential to quantify physical measurands such ...
متن کاملPassive wireless MEMS microphones for biomedical applications.
This paper introduces passive wireless telemetry based operation for high frequency acoustic sensors. The focus is on the development, fabrication, and evaluation of wireless, battery-less SAW-IDT MEMS microphones for biomedical applications. Due to the absence of batteries, the developed sensors are small and as a result of the batch manufacturing strategy are inexpensive which enables their u...
