Title: "The Development of Wireless Biomedical Sensors"

Abstract:
Personal Healthcare is gaining much attention recently. 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 wireless sensors will benefit millions of patients needing constant
monitoring of critical physiological signals anytime anywhere and help to improve the life
quality. One of examples 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. This talk will cover several low power
techniques used in the development of an ECG-on-Chip. Particular emphasis will be placed
on the frequency-response masking technique and the design of Ultra wideband transmitter.
