The health consciousness of our age is continually evoking development of new electronic technologies to improve medical practice, and health practice and fitness practice. Health care electronics cover a wide range of applications—from state-of-the art imaging equipment’s in hospitals and clinics to wearable appliances that consumers can buy over the counter. All of these help health professionals care for patients more effectively, and ordinary people assume more responsibility for monitoring their own health. Functional operation and reliability are critical in the design and manufacturing of integrated circuits (ICs) for medical systems.
