SIG – Wearable biosensors for remote health monitoring

Internet of things (IoT) has attracted huge attention because of its potential to connect things together with the cloud. Similarly, the Internet of Health (IoH) aims to enable real-time health evaluation of an individual or a group with advanced medical devices. This feat can be realized by developing tiny wearable biosensors that can be easily deployed on the human body to monitor health signals. This project develops next-generation wearable biosensors to allow digital healthcare. There are two main components. First, we develop skin-attachable biosensors which detect health signals including electrophysiological signals, temperature, and antibodies or glucose in the sweat. Second, we develop miniaturized sensor characterization systems to enable comfort wear for practical applications. The whole set can communicate the data wirelessly with other electronic devices. This will be one of the smallest wearable devices developed so far. Future research is being conducted by our group at the innovation wing now at HKU.

SIG – Quantum bit demonstrator

The world is currently in the midst of a second-quantum revolution, which will see the counter intuitive properties of quantum systems such as superposition and entanglement, being applied for commercial technologies such as quantum computing, quantum sensing, and quantum communications. Quantum Computing is mostly taught to undergraduates in a classroom focusing mostly on theoretical and mathematical concepts with minimal laboratory components. This is primarily because research laboratories working in quantum science are too expensive, bulky, and complicated to be used for undergraduate teaching purposes. We wish to bridge that gap by building a compact, user-friendly, interactive setup to introduce quantum physics to a younger non-expert audience. The goal of the project is to create a curriculum for quantum technology, a sustainable education model, with an in-class demonstration kit for quantum science education.

SIG – Smart Buildings and application of IoT

Internet of Things (IoT) is a system that connects sensors, machines, computing devices, etc. together to collect data without much human involvement. IoT allows a very massive amount of data to be collected, which were not available in the past. The data collected can then be used to enhance operation efficiency and performance of a system. The system then becomes “smart” in the sense that the system can now make decisions that are more optimized and intelligent without much human interaction. A home/building/city becomes smart when IoT is adopted in its maintenance and daily operations. IoT and smart city are still in infancies that there are not many real implementations. A complete IoT application consists of various components including sensors, power electronics, information processing, communication network, data analytics, data visualization, and data security etc. A lot of projects can be developed from these elements to provide experiential learning to our students.

HKU Racing 2020

Formula Student UK is an educational engineering competition. The competition aims to develop enterprising and innovative young engineers and encourage more young people to take up a career in engineering. Formula Student UK 2020 will be held at Silverstone Circuit, Towcester, UK. HKU team will join the Electric Vehicles Class 1 Division competition.

MEASURE: A SenseHat Smart Home Measuring System

This project fully utilises the sensors on SenseHat to build a SenseHat smart home measuring System MEASURE. There are three functionalities provided by MEASURE: Level meter, Compass, and HomeKit Integration. Level meter can detect if a line is horizontal or if a surface is flat, and a compass can calculate the degrees turned as well as finding correct directions. If not in use, MEASURE can be a perfect HomeKit accessory that reports readings to your device. So MEASURE is a smart tool that can detect temperature and humidity right at your mobile and help determine positions for furniture placement. It can also provide angle guidance for homemade DIY stuff, and assist you in many other areas.

Ping

When the internet first came into existence, it came with a mission: to bring people closer together. After more than 20 years of development, we have witnessed the birth of many life-changing innovations like social networks. They can help in connecting us with more and more people, even distant ones, yet only in a virtual form. This is where the problem starts to emerge: virtual content and connections are dominating our lives, disconnecting us from the real world. This is a problem we would like to address with Ping. It is a next-generation social network aiming at reconnecting our users back to reality so that our users will be able to pay more attention to the people and events around them, but not only to the virtual content shown on a 5-inch screen in front of them.

HKU Engineering students @ IBL Global Inclusive STEM+ Leadership week

This year marks the expansion of the Global Inclusive Leadership Program from China to Thailand. More than one thousand students in eighteen institutes from Greater China, Thailand and the UK participate in the leadership weeks. Students immerse themselves in a cross-cultural and social-mixing environment to develop and work closely together to come up with solutions that go beyond their training while adapting themselves in different cultural settings and developing global-minded perspective. For the participants, it is a journey of self-discovery and self-development. Among the values and skills students acquire in the program, innovative ideas, unconditional love and the spirit of teamwork stand out as the most noted and will help them to prepare for the future – a future of global citizenship. As one of the most respected educators in Thailand remarks: “it is truly an education of the twenty-first century.”

ClearBot: Decentralized Robot Swarms to Clean our Oceans

Ocean plastics destroy our natural marine and coastal habitats, endanger wildlife across the globe, pollute our food chain, and ultimately affecting the global water-food-energy nexus. Here, we present ClearBot, a scalable, AI-powered, plastic collecting intelligent robotic solution to address the ocean plastic epidemic with a sustainable community-centric symbiotic ecosystem.
