A joint research team co-led by City University of Hong Kong (CityU) has developed a new soft tactile sensor with skin-comparable characteristics. A robotic gripper with the sensor mounted at the fingertip could accomplish challenging tasks such as stably grasping fragile objects and threading a needle. Their research provided new insight into tactile sensor design and could contribute to various applications in the robotics field, such as smart prosthetics and human-robot interaction.

Energy-efficient light-emitting diodes (LEDs) have been used in our everyday life for many decades. But the quest for better LEDs, offering both lower costs and brighter colours, has recently drawn scientists to a material called perovskite. A recent joint-research project co-led by the scientist from City University of Hong Kong (CityU) has now developed a 2D perovskite material for the most efficient LEDs.

As the mechanisms of biomolecular interactions, which are the key to finding the causes of diseases and developing new drugs, have yet to be fully understood, developing the concepts and tools of multidimensional data analysis and image recognition can help adv

With the arrival of fifth-generation (5G) wireless technology, which is set to provide massive, ultra-high speed connectivity in the next five to 10 years, the development of sixth-generation (6G) technology is already on its way.

As high-speed rail and metro systems are rapidly developing in speed and complexity in many cities and regions, identifying effective ways to ensure their safe, reliable and efficient operation has become more pertinent. A multi-disciplinary research project, led by CityU, has developed a platform of tools to improve safety and reliability in railway system health monitoring, crowd safety and disruption management.     

Solar energy is the fastest-growing electricity source. But the commonly used silicon-based solar cells are close to their theoretical maximum efficiency and cost-reduction limit. At CityU, Professor Alex Jen Kwan-yue, Lee Shau-Kee Chair Professor of Materials Science, has been working on developing more stable and environmental friendly perovskite and organic solar cells, which are believed to offer more promising and diverse applications to replace silicon as the future of photovoltaic technology. 

Energy needs have skyrocketed in the past two centuries or more. The main energy sources, fossil fuels, are not only polluting, but also finite. Developing sustainable energy sources has long been a key global challenge. Professor Wang Zuankai, Associate Dean (Internationalisation and Industry Engagement) in the College of Engineering and Professor in the Department of Mechanical Engineering, has achieved research breakthroughs in efficiently converting the kinetic energy in water droplets into electrical energy, advancing research in water-based energy harvesting.

The strength-ductility trade-off has always been a dilemma in materials science.
