Welcome to LESSLESS (Low-Energy Sustainable Systems) is an interest group that operates as part of the 'Energy' research theme of the Pervasive Systems Centre (PSC), which spans the various ECS research groups. Its members are staff and students in the School of Electronics and Computer Science (ECS) at the University of Southampton, UK. LESS members have a common interest in energy harvesting, energy management, and low-power design.
Low-energy sustainable systems are receiving interest in many of the ECS research groups, with a number of high-profile projects including Next Generation Energy-Harvesting Electronics: Holistic Approach, VIBES, and TRIADE. LESS exists to bring together researchers in this field to increase communication, disseminate knowledge, and generate new ideas. Related activities in ECS include the coordination of the Energy Harvesting Network.
This website contains information on the members that make up LESS, and their research into energy harvesting, energy management, and low-power design. It also includes details of recent news and upcoming events and contact details for obtaining further information. LESS also brings us closer to our undergraduates, helping to disseminate the results of related student projects. The LESS interest group holds regular seminars and facilitates interaction between members via events including research seminars and tutorials.
News and Upcoming Events
Domenico Balsamo - a visiting PhD researcher from the University of Bologna, Italy - will give a seminar on the research project that he is undertaking at Southampton. This involves enabling computation to be sustained under conditions where the power supply is intermittent, through the use of saving state to non-volatile memory. This has particularly interesting application in energy-harves...
The Energy Harvesting Network's Data Repository has been used to compare linear and nonlinear harvester architectures in real applications. Linear resonant harvesters are shown to be the best choice for the majority of applications although nonlinear devices are better with more random vibrations. The full results of this work are available for download.
