Real Vibration Data Available for Free DownloadVibration energy harvesters behave very differently in real environments than when they are exposed to synthetic vibration conditions in the lab. To address this problem, we have collected long-term vibration data from a range of applications (including vehicles, machinery, and humans). These data sets are now available for free download from the Energy Harvesting Open Access Data Repository, which is managed by the Energy Harvesting Network. |

Holistic Energy Harvesting Design Explorer and Simulation ToolkitThe Response Surface Model-based Design Explorer (Windows .exe), pictured right, is available for download. It allows you to adjust the design of the vibration energy harvesting system and see what effect it has on the number of transmissions a wireless sensor node can make. This video explains how it works.An Energy Harvesting Simulation Toolkit (.zip) package, which includes documentation, may also be downloaded. |

Energy Harvesting Systems: A Block DiagramThe project has developed a block diagram of an energy harvesting system, which demonstrates the holistic approach that is needed for design. You can also download a document providing a full description of the various blocks in this diagram.

Follow-on Projects
Staying alive in variable, intermittent, low-power environments (SAVVIE)EPSRC Joint Research Grant: EP/K011979/1 & EP/K012908/1Institutions: University of Bristol and Newcastle University Start Date: 1 December 2012 Today's low-power electronic systems are designed to handle a high variability in the power demand, for example during transmissions from miniature wireless sensors. However these systems cannot cope with a highly variable power supply. If they are powered by an ambient energy harvester in an environment where the available power is low and sporadic, the system dies once the energy storage becomes depleted or damaged, with start-up being impossible if the power is not increased to a higher steady level. This project researches how to design robust and reliable electronics for situations where there is a variable, unreliable source of energy. A number of situations, or states, have been defined, according to the level of depletion of on-board energy storage, and how variable the power supply is. In the most challenging states, for example where the input power is sporadic and spread over a wide range from nW to mW, modern electronics fails. We call this the "survival zone" and are investigating a combination of techniques from the areas of power electronics and asynchronous microelectronic design to allow devices to operate in this zone. Techniques include control circuits that are able to ride through variable voltages, the detection of states, and reconfigurable hardware resources and control algorithms to suit sporadic and sub-microwatt input power. The chief aim of this project is to produce survival zone design methods for the microelectronic design community. |
