Professor Liudi Jiang is Professor of Materials and Electromechanical Systems within Engineering and the Environment at the University of Southampton.

Liudi Jiang obtained BEng in Microelectronics, MSc in Physics. She received her Ph.D. in advanced materials from the University of Dundee in 2002. This was followed by her postdoctoral fellowship at the University of Edinburgh on multidisciplinary research in developing novel materials, processes and electromechanical sensors for a range of applications etc. She was appointed a RCUK Academic Fellow (Roberts Fellow) in 2006 at the University of Southampton, Lecturer in 2008, Associate Professor in 2013 and then Professor in 2015. She is a Chartered Physicist.

Liudi currently leads a research group of 7 PhD students and 3 postdoctoral fellows with research projects spanning multidisciplinary areas of electromechanical sensors/actuators, functional materials and intelligent systems for many applications including e.g. biomedical, smart body interface, intelligent sensor/actuator systems, gait biomechanics, micro/nanoelectromechanical systems, and energy harvesting. She is currently the Director of Research for the Engineering Sciences Academic Unit.

------ “It’s important for research to have a broad view, for me the excitement comes from engineering advanced materials, devices and intelligent systems for new technologies which address unmet application needs.”

Research Interests

  • Biomedical sensors, actuators, systems
  • MEMS design, materials and processes
  • Electronic materials and devices
  • Energy harvesting technologies

Dr Jiang's research interests include applying electromechanical sensors and devices to address real-life challenges in many sectors. The following exemplar areas provide a current overview of her cross-disciplinary research activities:

Sensor technologies for healthcare

Sensor technologies for healthcare:

Load sensing and monitoring at the body-support interface is important for physical rehabilitation and can potentially be used to prevent skin ulcers and/or soft tissue breakdowns, which is affecting quality of lives of many patients. We are developing interfacial sensor systems underpinned by a novel sensor technology (supported by tissue viability studies) to provide practical solutions which bring benefit to a range of patients such as prosthetic and orthotic patients, diabetes, wheel chair users, and elderly people.

for non-volatile memories
Dielectric materials

Dielectric materials for non-volatile memories:

Transistor based RAM and flash memories are facing intrinsic limitation caused by further down-scaling. We are working on non-volatile resistive memories based on novel advanced material process research, which present one of the highest ON/OFF switching ratios reported and thus strong potential for future memory applications. Our dielectric materials also present advantageous electrical and mechanical properties which could be used as advanced interlayer materials in metal interconnect structures to reduce capacitive power losses and RC delays in integrated circuit.

for switch contacts
NT/metal composites

CNT/metal composites for switch contacts:

Switching contact surface with high electrical and mechanical performance is the key towards MEMS switches with high reliability and long life time, which remains a bottle-neck for the multi-billion ($) market worth MEMS switches/relay industry An unique CNT/metal composite material and processes have been developed for this application which has demonstrated orders of magnitude improvement in terms of cycles to failure tests under typical MEMS reply application conditions.
