Title: "Next Generation Energy Harvesting Electronics: Holistic Approach"
Speaker: Dr Alex Weddell, Electronics and Computer Science, University of Southampton
Date: Tuesday 31st May 2011
Time: 12.00
Location: Seminar Room 1, Zepler Building, Highfield Campus (59/1257)

The £1.6M EPSRC-funded “Next Generation Energy-Harvesting Electronics: Holistic Approach” project ( involves four UK universities and takes a complete approach to the development of energy harvesting systems. This talk will give an overview of the project – which includes the development of adaptive vibration energy harvesters, efficient power conditioning electronics, and energy harvesting-aware computation circuits (including ARM-based and asynchronous processors). We are also developing tools which can accelerate the simulation of these complete systems, facilitating the optimisation and synthesis of energy-harvesting devices. The project will deliver vibration harvesters that can adapt to changing vibration frequencies and amplitudes; power conditioning circuits which are designed to efficiently fit between the generator and the load; and smart processors that can use energy when it is available, at very low voltages and currents.

Alex Weddell was awarded his MEng degree by the University of Southampton in 2005 and studied for his PhD (awarded in 2010), entitled 'A Comprehensive Scheme for Reconfigurable Energy-Aware Wireless Sensor Nodes', at the same institution. He contributed to the Data Information Fusion Defence Technology Centre (DIF DTC) 'Adaptive Energy-Aware Sensor Networks' project and worked under the EPSRC platform grant 'New Directions for Intelligent Sensors'. He has experience with a range of energy harvesting devices and has developed a platform which supports a mix of energy sources to power an energy-aware wireless sensor node. He is now working on the 'Next Generation Energy-Harvesting Electronics: Holistic Approach' project, looking at energy device modelling and system-level design approaches.
