A study of SAW gas sensing versus gas concentration
1999 IEEE Ultrasonics Symposium. Proceedings. International Symposium (Cat. No.99CH37027), 1999An analytical expression for the SAW sensor gas response versus gas concentration (calibration curve) is deduced, at low gas concentrations, on using the perturbation approach. The calibration curve, the sensitivity (its slope) and the detection limit (threshold value) for a given gas and sorbent membrane, can be controlled by a proper choice of the ...

Optical Fiber Communication Conference (OFC) 2019, 2019
We present a photonic chip sensor platform for near-infrared laser absorption spectroscopy, which incorporates an uncooled III-V laser and detector, on-chip methane reference cell, and 30cm-long evanescent field waveguides, integrated on a silicon photonics substrate.

Selected aspects of gas sensing
Sensors and Actuators B: Chemical, 1998Abstract Based on the insight gained from the analysis of a previously developed model of metal oxide gas sensors and its comparison with results of experimental studies of automotive ZrO 2 oxygen sensors, this paper discusses our present understanding of the physical and chemical processes involved in the operation of these devices.

Making Sense of Blood Gas Results
Veterinary Clinics of North America: Small Animal Practice, 2008Recent technologic advances have allowed the production and marketing of cage-side blood gas analyzers to private practitioners. The widespread use of cage-side portable blood gas analyzers in veterinary practices has increased the need to develop the basic skills of blood gas analysis as part of a tool kit for practicing veterinarians. Rapid expansion

Introductory remarks on gas sensing
Sensors and Actuators B: Chemical, 1991Abstract The progress of mankind can be seen, from a certain point-of-view, as a continuous effort of the human being to reproduce himself artificially in order to reduce his physical fatigue and to make himself more powerful. The most recent gigantic advances in his capability to elaborate signals and actuate actions mechanically seem to reward such
