Título Towards Self-Powered Wireless Wearable Biomedical Sensors Resumo Personal Healthcare is gaining much attention recently due to the aging population and increasing healthcare cost. Personal healthcare advocates preventive healthcare through the adoption of healthier lifestyles. The goal is to distribute healthcare load between healthcare workers and each individual. To support the personal healthcare, it is necessary to develop an infrastructure to link each individual to healthcare providers. Body Area Network (BAN) combined with wearable technology is envisaged to create next era of patient management system that enables personal healthcare. Such systems allow continuous or intermittent monitoring of physiological signals and are critical for the advancement of both the diagnosis as well as treatment. With the advances of nanotechnologies and integrated circuits, it is possible to build implantable or wearable wireless biomedical sensors with combination of nano-structured biomedical sensor and wireless communication link onto a single chip. Such wearable wireless sensors will benefit millions of patients needing constant monitoring of critical physiological signals anytime anywhere and help to improve the life quality. This talk will cover several topics related to the BAN and share our experience in the development of a ultra low power BAN platform and wearable BAN devices. One of the essential components in the BAN is the electrocardiogram (ECG) device that monitors the cardiac status of patients. Such devices play a very important role to save life of patients who survive heart attack or suffer from serious heart diseases. With the advance of wireless communication technologies and integrated circuits, it is possible to build a wearable ECG device that can be embedded into clothing and is able to record ECG signals, detect abnormal ECG, and communicate to a mobile phone or PDA device if abnormal ECG signals are detected. The design of such ECG devices is very challenge due to the tight power constrain. Low power techniques must be adopted at all levels including algorithm development, system design, and circuits to reduce power consumption. A design example of a 450nW wearable ECG device, ECG-on-Chip, is discussed to illustrate the effectiveness of low power techniques.
