ABSTRACT
ENSORS CONVERT SIGNALS OF ONE type of quantity such as hydrostatic fluid pressure into an equivalent signal of another type of quantity, for example, an electrical signal. Biomedical sensors take signals representing biomedical variables and convert them into what is usually an electrical
signal. As such, the biomedical sensor serves as the interface between a biologic and an electronic system and must function in such a way as to not adversely affect either of these systems. In considering biomedical sensors, it is necessary to consider both sides of the interface: the biologic and the electronic, since both biologic and electronic factors play an important role in sensor performance.
