Event details

Dr Geoff Merrett looks at some case studies into the process and uses for energy harvesting.

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, Dr Merrett will discuss some of the challenges and solutions. 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. A range of data will also be presented on energy availability that has been collected, analysed and made freely available to the community.
