Towards a wireless microsystem for liquid analysis
UNSPECIFIED (2004) Towards a wireless microsystem for liquid analysis. In: IEEE Sensors 2004 Conference, Vienna Univ Technol, Vienna, AUSTRIA, OCT 24-27, 2004. Published in: PROCEEDINGS OF THE IEEE SENSORS 2004, VOLS 1-3 pp. 919-922.Full text not available from this repository.
This paper describes both semi-wireless and wireless (433 MHz) liquid sensing systems based upon dual shear horizontal surface acoustic wave (SH-SAW) devices and introduces a novel design concept and a novel principle of detection. Each system comprises an uncoated passive SH-SAW device, a liquid microcell, a device antenna and an associated signal processing unit. The LiTaO3-based SH-SAW sensors have dual delay line configurations with different path lengths and the principle of detection being the attenuation and time delay between the signals. The sensors have no bio-chemical selective layer making them non-specific but create a robust/durable and low-cost system. This sensing system may be applied in the food/beverage industry, medical applications; a functionalized coating can be added for more specific biological application.
