Hybrid Footstep Energy Harvesting System Integrated with Novel Battery

Description

To reduce the dependence on commercial electricity and support a green society, it is beneficial to develop an alternative to fulfil the power requirements. In order to enhance energy resilience and reduce greenhouse gas emissions, and cope with the rapid development of smart cities, new forms of sustainable renewable energy generation that complements existing sources such as solar and wind power are getting more and more interests. The present invention generally relates to hybrid energy harvesting floor system. More specifically the present invention relates to hybrid energy harvesting floor system based on electromagnetic and triboelectric generators.The synergistic energy harvesting floor system is particularly suitable to be installed underneath the tiles in the densely populated area to efficiently capture and convert the kinetic energy produced by pedestrians' walking. As EMG is efficient for low-frequency and high-output energy harvesting, while TENG works well for high-frequency and small-scale energy capture, the energy harvesting floor system can leverage the complementary strengths of both generators. The invention can also be fully integrated with power management component and energy storage component, and then feed into the city's infrastructure to support its normal functions.This innovative system is conducive to reduce the reliance on electrical source and promotes the use of renewable energy, contributing to a more sustainable subway infrastructure. The implementation of this project will not only encourage our team to develop more advanced energy harvesting technology, but also show our passion in environmental protection, energy saving and to embrace a zero-carbon society. In the short term, this project will fund the pursue of researchers in science, technology, and engineering field, and make the public aware of the fact that green technologies are under their feet. In the long run, it will lead to the dependence reduction on traditional electricity sources, electricity consumption decrease, non-centralized energy utilization promotion, and is contribute to the sustainable development of Hong Kong. The system will be integrated with novel battery developed by the same group for energy storage.
