ME Scholars win Gold Award in International Exhibition of Inventions of Geneva

Two Scholars of Department of Mechanical Engineering, have respectively won a "Gold award with the congratulations of jury” in the 45th International Exhibition of Inventions of Geneva:

Graphene/CNT-embedded Nanofibers for Clean Energy and Environment 
Principal Investigator: Prof. Wallace LEUNG

Inserting Graphene/Carbon Nanotubes (CNTs) into nanofibers results in fast transport of electron/charge in semiconductor nanofibers. It significantly increases the efficiency of solar cells for energy harvesting and photocatalysts for air purification by 40% - 66%.

 

Unmanned Aerial Vehicle (UAV) Communication Relay System 
Principal Investigator: Prof. Chih-yung WEN

The system enables multi-UAVs and cross-obstacle communications. It can make independent assessments for sending messages to coordinate a set of up to 13 UAVs. It helps overcome the restrictions posed by short communication ranges, and significantly improves the beyond-line-of-sight and cross-obstacle operation performances. Besides applying to quadrotors, the system is also compatible with otherUAVs adopting Micro Air Vehicle Link communication protocol, such as fixed-wing and helicopter systems.

The winning of top prizes in the international exposition not only have brought glory to Hong Kong, but the breakthrough also extended the frontiers of knowledge and enhanced the well-being of society.

The 45th International Exhibition of Inventions of Geneva, held from 29 March to 2 April, has attracted 725 exhibitors from 40 countries/regions, showcasing around 1,000 new products. Under the patronage of the Swiss Federal Government, the State and the City of Geneva as well as the World Intellectual Property Organization, it is the biggest event of its kind globally.
