Energy data from sources such as human motion, wind speeds and light irradiance that could be used to power wireless electronic devices is being made available to the world's scientific community, thanks to a new resource being launched this month.

The Open Access Data Repository is an online resource for researchers worldwide to share detailed data on and characteristics. It will be launched at the annual conference of the Energy Harvesting Network 'Energy Harvesting 2012'. The Network, which is funded by the Engineering and Physical Sciences Research Council and managed by the University of Southampton, brings together UK academic and industrial researchers and end-users of energy harvesting technology.

Energy harvesting is a means of powering wireless electronic devices by scavenging many low grade ambient energy sources, such as environmental vibrations, human motion, thermal gradients and light, so they can be converted into usable electrical energy. Energy harvesting devices are potentially attractive as replacements for primary batteries in low power wireless . They also hold the possibility of one day enabling the powering of a range of devices not currently possible, including implantable and wearable medical devices.

At present the data available for download includes detailed vibration data from a variety of transport and machinery applications and will be expanded to include data on wind, light irradiance and human body motion. All data is contributed by the community, and researchers are encouraged to upload their data. All data is available for free download and allows researchers to compare and evaluate their energy harvesting designs and analysis using a common dataset. The repository can be viewed by visiting eh-network.org/data

Dr Geoff Merrett, lecturer in Electronics and Computer Science at the University of Southampton and coordinator of the Energy Harvesting Network, says: "New energy harvesting devices and systems are being continually reported, but there is little standardisation in the way in which their performance is evaluated or compared. We have launched this data repository to not only provide researchers with real data to experiment with, but also to allow comparison between different devices using the same data. Obviously the success of the repository relies on its adoption by the community, both in using the data but also in further contributing to it, and I strongly encourage researchers to do so."

The 'Energy Harvesting 2012' event, on Wednesday 28 March in London, provides a platform for disseminating energy-harvesting advances in the UK, and contains presentations from well-respected speakers from academia and industry, demonstrations from companies, and posters from postgraduate students. Registration costs £50 (a subsidised rate of £25 is available for academics), while PhD students that bring and present a poster can attend for free (there are only a few poster spaces left).

Speakers at the event include Professor Peter Woias (IMTEK, Germany), Frank Schmidt (CTO Enocean), Professor Vittorio Ferrari (University of Brescia, Italy), Roy Freeland (Perpetuum) and Professor Eric Yeatman (Imperial College, London).
