Instrumentation Handbook for Biomedical Engineers

The book fills a void as a textbook with hands-on laboratory exercises designed for biomedical engineering undergraduates in their senior year or the first year of graduate studies specializing in electrical aspects of bioinstrumentation. Each laboratory exercise concentrates on measuring a biophysical or biomedical entity, such as force, blood pressure, temperature, heart rate, respiratory rate, etc., and guides students though all the way from sensor level to data acquisition and analysis on the computer. The book distinguishes itself from others by providing electrical circuits and other measurement setups that have been tested by the authors while teaching undergraduate classes at their home institute over many years.

Key Features:
? Hands-on laboratory exercises on measurements of biophysical and biomedical variables
? Each laboratory exercise is complete by itself and they can be covered in any sequence desired by the instructor during the semester
? Electronic equipment and supplies required are typical for biomedical engineering departments
? Data collected by undergraduate students and data analysis results are provided as samples
? Additional information and references are included for preparing a report or further reading at the end of each chapter

Students using this book are expected to have basic knowledge of electrical circuits and troubleshooting. Practical information on circuit components, basic laboratory equipment, and circuit troubleshooting is also provided in the first chapter of the book.

Mesut Sahin earned his B.S. degree in electrical engineering from Istanbul

Technical University in 1986. After graduation, he worked for a telecommunication

company, Teletas A.S., in Istanbul in hardware and software

development of phone exchanges until 1990. He earned the M.S. degree

in 1993 and a Ph.D. degree in 1998, both in biomedical engineering, particularly

in the field of neural engineering, from Case Western Reserve

University, Cleveland, Ohio. After post-doctoral training at the same

institute, he joined Louisiana Tech University as an Assistant Professor in

2001. He has been on the faculty of Biomedical Engineering at New Jersey

Institute of Technology, Newark, New Jersey since 2005, and currently is

a Full Professor, where he teaches bioinstrumentation and neural engineering

courses. His research interests are mainly in neural modulation

and development of novel neural prosthetic approaches. He has authored

more than 90 peer-reviewed publications. Dr Sahin is an Associate Editor

of IEEE Transactions on Biomedical Circuits and Systems and a Senior

Member of IEEE/EMBS.

Howard Fidel served as Vice President of Technology for IREX/

Johnson and Johnson Ultrasound, where he developed the market leading

Meridian Cardiology system. After leaving Johnson and Johnson in

1986, he founded Universal Sonics Corporation, as a contract engineering

company and a manufacturer of OEM Medical Devices supporting the

Ultrasound and Medical Device industry. Universal Sonics’ customer base

included many well-known clients, including ATL, Acuson, Biosound, and

many others. After the acquisition of Universal Sonics by US Surgical, Mr.

Fidel left to become Chief Operating Officer of Stern Ultrasound, a startup

company that was in the process of developing a mid-market ultrasound

system. Later he functioned as C.T.O. and C.O
