Invited Talk at ACROSS Workshop 20132nd October 2013
I have been invited to give a talk at the 1st ACROSS Workshop on Cooperative Networked Embedded Systems, in Zagreb. The workshop, which will take place in November 2013, is funded by the EU FP7 Centre of Research Excellence for Advanced Cooperative Systems (ACROSS) project. My talk, titled "From sensors to networks: harvesting and utilising environmental energy", will discuss the role of energy harvesting in sensor nodes and sensor networks.

Abstract: With new computing paradigms on the horizon such as pervasive computing and the internet of things, interest in wireless autonomous sensing has been increasing rapidly over the past decade. One of the fundamental challenges which exists in this area is how to power such devices, where design constraints typically include being small, light-weight and long-lasting. Energy harvesting - the process of extracting electrical energy from the surrounding environment - has been hailed as a potential solution for this, but its effective integration into a complete sensing system is non-trivial. In this seminar, I will discuss some of these challenges and solutions - from the design of a single sensor node to managing energy across a complete network. Some of these aspects will be illustrated in the context of case-studies, both in constrained and real applications, including a wireless sensor performing condition monitoring on a ferry engine which is powered by a tuneable vibration-based microgenerator.

Tactile Devices Trialed on Stroke Patients19th November 2010
'Phase 3' of the human evaluation of the haptic devices that we have been developing is now complete.
The human evaluation section of this project had four phases; phases 1, 2 and 4 testing the devices on normal subjects, with phase 3 testing on partipicants with stroke.
The information and feedback that we have received from these trials has been invaluable in influencing the design of the devices, and has uncovered a wealth of information on the sensory perception of people following str... [more]
Two Papers Accepted for Publication in IEEE Transactions26th September 2011
We have recently had two papers related to our work on Energy Harvesting electronics accepted for publication in the IEEE Transactions on Circuits and Systems. Both publications are a result of the EPSRC project on 'Holistic Energy Harvesting'.
The first paper, 'Accurate Supercapacitor Modeling for Energy-Harvesting Wireless Sensor Nodes' investigates supercapacitors, often used in energy-harvesting wireless sensor nodes (EH-WSNs) to store harvested energy. Until now, research into the use of... [more]
