Ocean Wave Energy Harvesting Technology
(REF: S-1784) |
| Trial Project |
|
| Solution Feature |
- Based on the chaotic pendulum design and high-efficient electromagnetic coupling effect
- Device consisted of omnidirectional pendulum-based WEH (P-WEH) module, a power management module, a data acquisition (DAQ) module and an Iridium communication module
- The irregular voltage output is regulated, boosted and stored in a lithium battery, and then provides stable power supply to those sensors of ocean observing platform
- Generated voltage data can be transmitted via Iridium Satellite and utilized for evaluating and sensing the real-time wave conditions, i.e., wave height and period
- Omnidirectional free degree of a planar pendulum design, as well as the high-efficiency electromagnetic coupling effect
|
| Trial Application and Expected Outcome |
- an omnidirectional and high efficient built-in WEH system, realizing both energy harvesting and self-powered wave sensing at the same time
- The high output power of 520 mW and power density of 0.66 mW/cm3 can be achieved under the ultra-low frequency wave excitation
- The P-WEH module can harvest wave energy and provide a stable voltage source of 8.4 V for the AIS positioning sensor.
- combined with the DAQ module as a self-powered wave sensor to assist ocean observation studies
- built-in WEH system integrated with the ocean observation buoy can be used as a wave monitoring sensor and energy harvester at the same time
