Application of engineering techniques in bio-medical sciences is gradually expanding. Today, with the ever increasing complexity of medical technology, there is a growing demand for technical professionals that could inter-relate the fields of bio-medical and engineering. Personnel that are capable of understanding a medical problem in terms of engineering sciences will be able to solve problems that are of interest to engineers and medical practitioners. This new field of Bio-Medical Engineering has made significant contributions in the technological advancement in the field of medicine, such as the creation and production of artificial human parts, communication aids and assisstive tools for the handicapped, new diagnostic and therapeutic tools that lead to new medical procedures, etc. The use of equipment and devices in modern medicine is so prevalent that we cannot imagine a situation without it. It has even come to the stage where there are now medical devices for home use.
