Tire Pressure Measurement Using a Saw Hybrid Sensor
A tire pressure measuring system based on surface acoustic wave (SAW) sensors is presented. Since SAW sensors are powered by the energy of the RF field no battery is required, which is a major drawback of conventional systems. A successful combination of a SAW reflective delay line with a capacitive pressure sensor is shown. With a new way of matching the sensor impedance to the SAW reflector i...
متن کاملA Phase - Locked Loop based Module for SAW Sensor Electronics
Acoustic wave microsensors are increasingly popular recently for their potential applications in wireless communication, defence, space and portable systems. The advantages of surface acoustic wave (SAW) devices include smaller size, rugged, high sensitivity and quasi-digital frequency output [1]. The system design requires the electronic modules to measure changes in SAW velocity and insertion...
متن کاملRapid SAW Sensor Development Tools
The lack of integrated design tools for Surface Acoustic Wave (SAW) devices has led us to develop tools for the design, modeling, analysis, and automatic layout generation of SAW devices. These tools enable rapid development of wireless SAW sensors. The tools developed have been designed to integrate into existing Electronic Design Automation (EDA) tools to take advantage of existing 3D modelin...
متن کاملSensitivity Improvement of Wireless Pressure Sensor by Incorporating a Saw Reflective Delay Line
this paper presents a wireless surface acoustic wave (SAW) pressure sensor on 41YX LiNbO3 for tire pressure monitoring system (TPMS) application, in which a reflective delay line composed of an interdigital transducer (IDT) and several reflectors was used as the sensor element. Using the coupling of modes (COM), the SAW reflective delay line was simulated, and the optimal design parameters were...
متن کاملContinuous in vivo blood pressure measurements using a fully implantable wireless SAW sensor
In this paper, the development of a fully implantable wireless sensor able to provide continuous real-time accurate pressure measurements is presented. Surface Acoustic Wave (SAW) technology was used to deposit resonators on crystalline quartz wafers; the wafers were then assembled to produce a pressure sensitive device. Excitation and reading via a miniature antenna attached to the pressure se...
