Contents I. Introduction
Advanced medical devices constitute a fast growing market and provide countless opportunities to technology innovation. These medical devices are critical and irreplaceable, since they can relieve patients' pain, improve their life quality, and extend life span, sometimes, save their lives. Especially with the background of global aging, chronic diseases, like heart diseases, and diabetes etc. are becoming the major cause of death around the world, and are also accountable for the major cost of social healthcare expenditures [1]. There is a serious need for advanced medical sensors and systems for quick and accurate diagnosis, at the meanwhile, lowering down the total cost to ease the society's financial burdens for the elder care. Research groups from academia and industrial companies are making concerted efforts to boost research and development activities for the next generation biomedical technologies. e.g. personalized, predictive, and preventive healthcare technologies [2], [3].
