Biomedical Transducers

Abstract

A transducer is a device that converts a measured object quantity into an electrical signal. Biomedical transducers are transducers with specific uses in biomedical applications, such as physiological measurement and patient monitoring, and in health care. The object quantities in biomedical measurements are physical and chemical quantities that reflect the physiological functions in a living body. Although some quantities, such as blood composition, can be determined from a sample extracted from the body, real‐time and continuous measurements can be achieved if a transducer is attached to the body, and use of a transducer attached to the body is essential when continuous monitoring of an object quantity is required.

Improved Interpretation of Flow Maps Obtained by Scanning Laser Doppler Flowmetry Using a Rat Model of Retinal Artery Occlusion

“…The absence of a gold-standard technique for measuring the heterogenous distribution of retinal and choroidal blood flow precludes a simple in situ calibration. 23 In conclusion, the Brown Norway rat is a useful model to aid in the interpretation and validation of HRF flow measurements. Our results have confirmed that there is a significant amount of flow-related information in the HRF map obtained from the current instrument.…”

A New System for Continuous Monitoring of Breathing and Kinetic Activity

“…In past years two main methods for breathing monitoring have been developed [3][4][5][6][7]. In the first method, the air flow is sensed while in the second one the breast dilatation is sensed.…”

A review of low‐power wireless sensor microsystems for biomedical capsule diagnosis

“…Based on the miniaturization and encapsulation technologies, a number of swallowable wireless telemetric devices appeared. These devices included the ability to measure temperature (CorTemp w ) (Togawa et al, 1997), pressure (Rigel Ltd) (Kingham et al, 1984;Thompson et al, 1980) and pH (Heidelberg and Bravo capsules) (Barrie et al, 1992;Pandolfino et al, 2003;Ruan et al, 2003) within the GI tract. A summary of these ingestible pills is given and listed in Table III.…”
