Newer biomaterials even incorporate living cells in order to provide a true biological and mechanical match for the living tissue. The aspect of Biomedical Engineering in which engineering strategies, techniques, and tools are used to gain a comprehensive and integrated understanding of the function of living organisms ranging from bacteria to humans. Modeling is used in the analysis of experimental data and in formulating mathematical descriptions of physiological events. In research, models are used as a predictive tool in designing new experiments to refine our knowledge. Living systems have highly regulated feedback control systems, which can be examined in this way.
Examples are the biochemistry of metabolism and the control of limb movements.
The manipulation and dissection of the data or signal provides the physician and experimenter with vital information on the condition of the patient or the status of an experiment. Biomedical Engineers apply signal-processing methods to the design of medical devices that monitor and diagnose certain conditions in the human body. Often, these images can be obtained with minimal or completely non-invasive procedures, making the less painful and more readily repeatable than invasive techniques. It includes the study of motion of motion, of material deformation, of flow within the body and in devices, and transport phenomena in the body, such as transport of chemical constituents across biological and synthetic media and membranes. Efforts in biomechanics have developed the artificial heart and replacement heart valves, and the hip replacement.
