Biomedical instrumentation notes

Even though there is a wide variety of instruments, almost all of them can be modeled using the simple diagram below.
Basic model of instrumentation systems.
All biomedical instruments must interface with biological materials (by definition).
The interface can by direct contact or by indirect contact (e.g., induced fields).

Finally, the various safety standards for biomedical instrumentation are introduced, including:

BIOMEDICAL INSTRUMENTATION In this course, we will study the principles and the design of biomedical instrumentation for the non-invasive measurement of physiological parameters known as the "vital signs".
We will cover four of the most important vital signs which can be measured non-invasively:
