2. Air-Conditioned Facemask

Gold Award and Special Award at the 35th World Genius Convention and Education Expo 2021
Gold Medal and Grand Award (Excellence in Innovation Award) at the 13th European Exhibition of Creativity and Innovation (EUROINVENT) 2021

Principal Investigator: Dr Dahua Shou, Institute of Textiles & Clothing
This new facemask integrating a 3D printed frame and a thermoregulation unit aims to strike a balance between effective personal protection and wearing comfort.

To empower customers to realize their own design visions into products, this web-based application involves users in the processes of designing and producing their desired high heel shoes. Users can experiment with the adjustable sets of parameters to design fashionable heels of desired fit, aesthetics and performances, and generate a variety of outcomes. Selected designs can be fabricated through 3D printing and made-to-order procedures. The application offers a convenient communication platform for customers and additive manufacturing suppliers and factories, on which order placement, inventory coordination, shipping arrangements and status tracking can be performed digitally for maximum efficiency and minimum wastage.

 

7. Total Pressure Management and Balance-enhancing Geriatric Footwear

Principal Investigator: Dr Kit-lun Yick, Institute of Textiles & Clothing
Our geriatric footwear aims to improve balance control and planter pressure distribution in elderly people. It helps to prevent falls and various problems related to excessive or uneven plantar pressure, such as loss of sensation, reduced mobility and foot ulcers. The footwear consists of a number of balance-enhancing components, including a flexible heel counter, arch support and detachable silicone nodules. Catering to varying needs of individual wearers, those nodules can be strategically placed on specific areas to stimulate and enhance plantar sensations as well as reduce and redistribute plantar pressure for better walking stability and wearing comfort.

 

8. Anti-viral and Anti-microbial Durable Disinfectant Coatings for Facemask

Principal Investigator: Prof. Xiao-ming Tao, Institute of Textiles & Clothing
This project aims to develop a series of green disinfectants based on poly (3-hydroxybutyrate) (PHB) oligomer and its homologues, using a rapid synthesis technique which involves cost-effective processes. The disinfectants produced in this way demonstrate wide-spectrum anti-microbial properties against fungi and bacteria, with a remarkable anti-bacterial rate of over 99.99%. They can effectively kill influenza viruses, such as H1N1 and H3N2, with an anti-viral activity rate of 99.99%. Moreover, these disinfectants are non-toxic and biodegradable, and can be applied as aqueous coating solutions over facemasks and other personal protection equipment for enhanced disinfection efficacy.
