Abstract:
The £1.6M EPSRC-funded “Next Generation Energy-Harvesting Electronics: Holistic Approach” project (www.holistic.ecs.soton.ac.uk) 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.

Biography:
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.
