Ethylene oxide has been used as a fumigant for foods, textiles, and soil, and for sterilizing biomedical instruments. It readily diffuses through materials without damaging them. Its antibacterial effect is probably due to its ability to alkylate critical cellular enzymes.

Within the next 5-10 years the use of ISE type devices for continuous monitoring during surgical procedures and at the bedside of critically ill patients should become commonplace. While there are still problems to overcome, recent experiments with animals have already demonstrated that such measurements are feasible. It is probable that biomedical instrument manufocturers will produce both extracorporeal (e.g., the Miles Biostator already mentioned) and catheter-type systems for continuous detection of blood electrolyte levels. The use of telemetry for monitoring ISE potentials will undoubtedly play a major role in the development of the catheter devices. Ideally, one can envision, in the near future, operating nrams equipped with in vivo or extracorporeal devices and video screens which continuously display the patient s electroijrte levels just as blood pressure and heart rates are currently monitored.

The first part of this chapter presents the basic sensing principles (of physical sensors) that are used in biomedical instruments. Sensors that operate on these principles convert physical parameters into electric signals. An output from a sensor in the form of an electric signal is preferable because of the advantages of subsequent processing of electrical signals. Basic physical sensors include piezoelectric, resistive, inductive and capacitive sensors.

The mold and punch can be constructed by a biomedical instrumentation shop, but are simple enough to be constructed in the laboratory. In theory, larger arrays can be constructed, such as for double wide (brain) slides or raw nitrocellulose membranes, measuring up to 40 by 45 mm. However, the final frozen array should not be larger than what can be cut on a cryostat or the size of the final support surface. Currently, the array block mold and punch are not available commercially.

In addition to its nonpolarizable behavior, the silver-silver chloride electrode exhibits less electrical noise than the equivalent polarizable electrodes. This is especially true at low frequencies, and so silver-silver chloride electrodes are recommended for measurements involving very low voltages for signals that are made up primarily of low frequencies. A more detailed description of silver-silver chloride electrodes and methods to fabricate these devices can be found in Reference 3 and biomedical instrumentation textbooks [4]. 

Biopotential electrodes are one of the most common biomedical sensors used in clinical medicine. Although their basic principle of operation is the same for most apphcations, they take on many forms and are used in the measurement of many types of bioelectric phenomena. They will continue to play an important role in biomedical instrumentation systems. 

Detailed information on the realization of amplifiers for biomedical instrumentation and the availability of commercial products can be found in the references and in the data books and application notes of various manufacturers of integrated circuit amplifiers, such as Burr-Brown, Analog Devices, and Linear Technology Corporation, as well as mamrfacturers of laboratory equipment, such as Biopac Systemy Inc., Gould, and Grass.

Fluid (gas, liquid) systems such as natural gas supply or water supply use flow meters, the devices that can be used to estimate the amount of fluid supplied. They are also found in automotive applications in engine control and emission and in fuel flow and consumption and in biomedical instrumentation [1]. A trend over the last decade has been to develop biochemical sensors that are very small in size. Typical...
