Advances in energy harvesting using low profile piezoelectric transducers

14 March 2007 | Shashank Priya
The article "Advances in Energy Harvesting Using Low Profile Piezoelectric Transducers" by Shashank Priya reviews recent developments in piezoelectric energy harvesting, focusing on low-profile transducers. The author highlights the importance of developing on-site generators to transform available energy into electrical power, particularly in remote or inaccessible locations where battery charging or replacement can be costly and tedious. Piezoelectric energy harvesting is emphasized as a prime method for converting mechanical energy into electrical energy, with a detailed discussion on the selection of piezoelectric materials for on and off-resonance applications. The article also analyzes analytical models describing the efficiency and power magnitude of the energy harvesting process. The introduction covers the potential energy sources, such as industrial machinery and human activity, and compares the cost-effectiveness and reliability of different energy harvesting approaches, including solar, thermoelectric, electromagnetic, piezoelectric, and capacitive schemes. The article concludes that piezoelectric transducers are more suitable for kinetic to electrical energy conversion due to their smaller size, lighter weight, and higher energy density compared to other methods.The article "Advances in Energy Harvesting Using Low Profile Piezoelectric Transducers" by Shashank Priya reviews recent developments in piezoelectric energy harvesting, focusing on low-profile transducers.
