Medical Electronics

Most of my professional experience is in the design of medical electronic devices. The book Design and Development of Medical Electronic Instrumentation contains many of my favorite building blocks for amplifying, processing, simulating, and evoking biopotentials.

The book provides real-world projects that range from simple biopotential amplifiers all the way to a computer-controlled defibrillator. With access to an ftp site that contains the software and information needed to successfully complete the projects outlined, this book will help one quickly master the essentials of medical device design and build sophisticated instrumentation for a broad range of purposes.

You may also be interested in the circuits and methods presented in Design and Development of Medical Electronic Instrumentation if you are designing low-noise, low-level amplifiers, filters, data acquisition systems, etc. People have told me they use the circuits and software presented in the book for the acquisition and analysis of ELF geomagnetic signals, seismometers, construction of chemical and biological agent sensors, micropower sensors, nuclear particle detectors and other scientific instruments.
