The objectives of this research program are to develop non-invasive sensors and techniques for: (1) continuous monitoring of physiological activities and parameters; and (2) quantitative characterization of biomedical tissues, using piezoelectric and ultrasonic techniques. These objectives will require investigation of optimal sensor design and configuration, design and construction of a signal acquisition system, and development of algorithms and computer programs using digital signal processing techniques to retrieve the desired signals and useful information for monitoring of physiological conditions and medical diagnosis. I will develop a portable and remote continuous health monitoring system based on sophisticated wearable sensor technology, and a robust and advanced quantitative ultrasonic imaging system to assist medical practitioners in making fast, accurate and appropriate diagnosis. These technologies will enable people to live comfortably and healthfully at home. They will be able to wear low cost sensors that will continuously monitor their health and transmit that information to well trained health care professionals. The monitoring and signal processing can be conducted remotely and therefore the data will be transferred via a wireless connection to a PC, PDA (personal digital assistant), or cell phone. Quantitative characterization and elastic imaging of biomedical tissues could provide accurate and significant information to medical specialists, such as the detailed feature, degree and area of diseased tissues.

本研究计划的目标是开发非侵入性传感器和技术，用于：(1)连续监测生理活动和参数；(2)利用压电和超声技术对生物医学组织进行定量表征。这些目标将需要研究最佳传感器设计和配置，设计和构建信号采集系统，开发算法和计算机程序，使用数字信号处理技术检索所需的信号和有用的信息，以监测生理状况和医学诊断。我将开发一种基于先进的可穿戴传感器技术的便携式远程连续健康监测系统，以及一种强大而先进的定量超声成像系统，以帮助医生做出快速，准确和适当的诊断。这些技术将使人们能够在家里舒适、健康地生活。他们将能够佩戴低成本的传感器，持续监测他们的健康状况，并将这些信息传递给训练有素的医疗保健专业人员。监控和信号处理可以远程进行，因此数据将通过无线连接传输到PC、PDA（个人数字助理）或手机上。生物医学组织的定量表征和弹性成像可以为医学专家提供准确而有意义的信息，如病变组织的详细特征、程度和面积。
