Bioinstrumentation

Addresses measurements in new fields such as cellular and molecular biology. Equips readers with the necessary background in electric circuits. Statistical coverage shows how to determine trial sizes.

Bioinstrumentation deals with the instrumentation techniquesand principles used for measuring physical, physiological,biochemical and biological factors in man or other livingorganisms. This book provides a comprehensive knowledgeabout the basic principles and applications of the tools andtechniques generally used in biology and also those used in thegrowing field of molecular biology. This book will prove to be adependable reference book for students and teachers ofbiological sciences.

This reference text consists of contributed chapters by specialists directly carrying out research and development in this emerging field which joins advanced microelectronics with modern biotechnology. Chapters present novel biotechnology-based microelectronic instruments, such as those used for de

This short book provides basic information about bioinstrumentation and electric circuit theory. Many biomedical instruments use a transducer or sensor to convert a signal created by the body into an electric signal. Our goal here is to develop expertise in electric circuit theory applied to bioinstrumentation. We begin with a description of variables used in circuit theory, charge, current, voltage, power and energy. Next, Kirchhoff's current and voltage laws are introduced, followed by resistance, simplifications of resistive circuits and voltage and current calculations. Circuit analysis techniques are then presented, followed by inductance and capacitance, and solutions of circuits using the differential equation method. Finally, the operational amplifier and time varying signals are introduced. This lecture is written for a student or researcher or engineer who has completed the first two years of an engineering program (i.e., 3 semesters of calculus and differential equations). A considerable effort has been made to develop the theory in a logical manner--developing special mathematical skills as needed. At the end of the short book is a wide selection of problems, ranging from simple to complex.
