Biomedical transducers are essential instruments for acquiring many types of medical and biological data. From the underlying principles to practical applications, this new book provides an easy- to-understand introduction to the various kinds of biomedical transducers. The first comprehensive treatment of this subject in 20 years, the book presents state-of-the-art information including: discussions of biomedical transducers for measurements of pressure, flow, motion, temperature, heat flow, evaporation, biopotential, biomagnetism, and chemical quantities.
