A Course on Biomedical Instrumentation Utilizing Laboratory Based on System Design ApproachThe paper expounds how within the curriculum of an Electrical and Computer EngineeringTechnology program, the biomedical course is redesigned so that the students can follow thetheory with laboratory experiments based on Biomedical System Design approach. Isolatedexperiments focused on a single topic never conveyed the holistic feel that is gained through acomplete instrumentation platform design.This course is offered in the form of Learning Modules. The paper discuses the coursesystem design modules in details which encompasses: Transducer theory, Human Physiology,Microcontrollers based Embedded System design and Embedded SystemProgramming, Object-Oriented Programming (OOP), Design and use of Graphical UserInterface (GUI), Electronics and use of Analog Devices.Biomedical System Design platform consists of a Microcontroller based system interfaced with aPersonal Computer (PC). The Microcontroller based system will acquire a particularphysiological signal. The microprocessor will perform digitization of the signal and capture therelevant data dedicatedly in real time basis. The data is further communicated to PC through ahost of data communication protocols. The data is analyzed by a number of application programsdesigned by students. The students also design Graphical User Interface (GUI) application thatoperates on the stored data from the files and implements a number of operational parameterslike alarms and physiological variables.Redesigning of the course with this approach benefits the institution in establishing a laboratorywithout commercial instrumentation that is cost prohibitive. Commercial instrumentationutilizes the proprietary technology that is not comprehendible and not amenable and acquiescentto student’s learning. This approach provides a unique opportunity for the students, to learninstrument design and development in the biomedical area from concept to completion. TheSystem Design approach will provide the students lifelong learning experience that preparesthem for their professional life.
