- Dr Jize Yan will move to the University of Southampton as an Associate Professor in the School of Electronics and Computer Science in 2016.
- Self-powered wireless MEMS sensor system (MEMS sensors, energy harvesting and wireless sensor network) (supported by CSIC, EPSRC, TSB and industrial funds): In order to manage infrastructure assets efficiently and safely, engineers will require more detailed information about structural performance. A key source of this information will come from monitoring data. However, installing traditional wired monitoring systems on large-scale civil infrastructure assets is time consuming and expensive. An alternative is to use WSNs that are faster to install and potentially cheaper on the sensor-by-sensor cost basis. Advances in the development of miniature MEMS sensor, WSN and energy harvesting offer new possibilities that can radically alter the paradigms underlying existing methods of condition assessment and monitoring of ageing civil engineering infrastructure.
- Distributed optical fibre sensor (supported by CSIC, EPSRC, TSB and industrial funds): Although strain measurement is well established, current practice has until recently been restricted to measurement of point-wise strains by means of vibrating wire (VWSG) or metal foil strain gauges and more recently by fibre optics utilising Fibre Bragg Grating (FBG) technology. Distributed optical fibre sensors (such as BOTDR and BOTDA) allow measurement of strain and temperature at any location along a standard single fibre sensor of 10-30 km. Long distance, dynamic, high resolution, single ended FO sensing are still open issues in the field. The research will advance the DOFS to the dynamic level utilizing the essential benefits in both Brillouin-scattering and Rayleigh-scattering to monitor the temperature and strain dynamically and continuously over very long-distance in real applications to understand the continuous behavior of large infrastructure such as bridges, piles, buildings, highway, dams, tunnels and railway. This unique feature, having no parallel in conventional sensing systems, will open new possibilities for infrastructural health monitoring.
- Energy recovery, monitoring and control of electrochemical synthesis (supported by C4T, National Research Foundation Singapore and industrial funds): Emerging research coupling chemical synthesis with electrical current generation has evolved from battery, fuel cell, and electrosynthesis technologies. Realisation of electrochemical cogeneration and synthetic methods with exquisite control of reaction parameters, requires technological innovation, new directions in electrochemical reactor engineering and mechanistic understanding of the electrolytic reactions. The research will deliver high sensitivity electroanalytical methodologies, control and monitor the electrical energy to deliver the energy recovery during chemical synthesis to reduce the net carbon emission. An example project:
- Today, Li-ion batteries are widely used as a portable power sources for various electrical and electronic devices. In order to cope with more applications, Li-ion batteries are being made lighter, more durable and powerful. However, due to the nature of a Li-ion battery, associated use and safety issues in actual practice (including fires and explosions) are not negligible. Intelligent monitoring and power management will offer a system level of solution and open new opportunities for smart energy control for industrial applications.
