Faculty of Engineering & Science

Ruiheng Wu received his BEng and MEng degrees from Tianjin University in 1982 and 1986 respectively. Following 10 years as a faculty member in the Department of Electronic Engineering at Tianjin University and two years research at the City University of Hong Kong, he joined the Analogue Circuit Design Research Group at Oxford Brookes University as a PhD student in January 1999, where he completed his PhD thesis entitled 'Design of Wide Bandwidth High Linearity Amplifiers'. In January 2002, he joined the School of Engineering, University of Greenwich.

He is a senior lecturer in Electronic Engineering. Dr Wu's general research interests are in the area of RF circuits and systems, RFID and its applications in localisation and healthcare, life search and rescue and remote health monitoring. As a principal investigator, he has completed a number of industrial and research projects, and has several publications. Dr Wu is a senior member of the IEEE and a member of the IET (IEE) Kent Committee, an honorary senior visiting research academic of Oxford Brookes University,, and Guest Professor at the College of Information Technical Science, Nankai University, and at the School of Electronic Information Engineering, Tianjin University.

Dr Wu has been a guest professor at the School of Electronic and Information Engineering, Tianjin University, China, a guest professor at the College of Information Technical Sciences, Nankai University, China, an honorary visiting senior research academic at Oxford Brookes University, U.K.

He is a member of the IET Kent Local Committee

Dr Wu's general research interests are in the area of analogue circuits and systems design, and RF circuits and systems. In recent years, his research activities have focused on life search and rescue, plus remote health monitoring using modern wireless technologies.

His research on the remote health care and monitoring system has achieved very promising results, providing a first line of defence for elderly patients, patients with systemic disease, and patients with high risk of cardiopulmonary events. These patients benefit from having their vital signs monitored continuously with any emergency situations transmitted immediately to a central monitoring station or first responder.

Funded research projects

Research areas include 'Self-alerting Safety Jacket (SAS Jacket)', an EU FP7 project. Wu was the principal investigator at the University of Greenwich for this project. The aim of the project was to develop a personal alert and location system to be used in life vests/lifejackets. The 'self-alerting' life vests would be used by maritime and inland waterway employees, passengers, and by recreational sailors, with potential for extended use for other health and safety alerting and locating. It is expected that the project and its results will meet the pressing need for innovation in reducing the number of lives lost at sea and on inland waterways, providing maritime and other disaster search and rescue (SAR) operations with an effective and efficient tool.

Another research area was examining remote healthcare via wireless communication tools. The aim of the research was to develop a remote Personal Emergency Response System(PERS)  based on multiple vital signs monitoring to be used by elderly and the people with long term condition at home. This system is to provide a first line of defence for elderly patients, patients with systemic disease, or patients with high risk of cardiopulmonary events. This included wireless monitoring for pulse, blood pressure and blood oxygen saturation level etc. The research team obtained very exiting results in the non-invasive blood glucose monitoring using microwave cavity perturbation. One paper has been published in Electronics Letters and the paper has been invited to be featured on this topic.

Another research area is Bio-RFID and its applications in disaster search and rescue operations and healthcare. The project is to develop an effective and efficient system for the detection, identification and localisation of the victims in disasters, such as trapped people in collapsed buildings after earthquakes, by using Radio Frequency Identification (RFID) technique. The proposed idea could also be applied to develop a RFID Personal Emergency Response System (PERS) and other healthcare applications. The project is supported by the university Proof-of-Concept Fund. So far, the results are very promising. A patent application based on the results has been submitted.

He has also done research on highly linear RF amplifier design for many years, and has published papers in various journals and conferences. Recently, a highly linear RF amplifier IC chip based on his research results has successfully been manufactured.
