TAILIEUCHUNG - SUSTAINABLE ENERGY HARVESTING TECHNOLOGIES – PAST, PRESENT AND FUTURE

In the early 21st century, research and development on sustainable energy harvesting (EH) technologies have started. Since then, many EH technologies have evolved, advanced and even been successfully developed into hardware prototypes for proof of concept like Helimote, AmbiMax, et al. Researchers from all around the world are devoting their precious time and efforts into finding a realistic and novel energy harvesting solutions for sustaining the operational lifetime of low‐power electronic devices like mobile gadgets, smart wireless sensor networks, etc | SUSTAINABLE ENERGYHARVESTING TECHNOLOGIES - PAST PRESENT AND future Edited by Yen Kheng Tan Sustainable Energy Harvesting Technologies - Past Present and Future Edited by Yen Kheng Tan Published by InTech Janeza Trdine 9 51000 Rijeka Croatia Copyright 2011 InTech All chapters are Open Access distributed under the Creative Commons Attribution license which allows users to download copy and build upon published articles even for commercial purposes as long as the author and publisher are properly credited which ensures maximum dissemination and a wider impact of our publications.
