SEOUL, Feb. 2 (Korea Bizwire) — The Korea Institute of Science and Technology announced the development of new technology that can produce electrical energy by adapting itself to various vibrations generated in surrounding environments.
A research team from the institute developed an energy harvester that can convert resonant frequencies for itself depending on changes in surrounding environments.
Since vibration occurs at diverse frequencies in everyday life, the natural frequency of the energy harvester should be adjusted every time to ensure optimal performance during actual use.
To overcome such limits, the research team developed a new structure by adding several clamps to the energy harvester, thus making it change its natural frequency depending on the change in nearby frequency.
The newly-developed energy harvester can adjust resonance for itself within 2 seconds in the frequency range over 30 hertz (Hz), and is therefore able to produce electricity even when the adjacent frequency is changed.
Fixing the energy harvester to a car engine during actual driving conditions enabled a continuous power supply to a wireless location tracking device.
