Textiles woven with yarn are used in remote medical diagnosis
with intelligent electronic sensing technology. However, the derived
inconsistent signals are one of the problems yet to be solved.
New research published in Advanced Materials and led by a
student at City University of Hong Kong (CityU) was inspired by
the structure of deoxyribonucleic acid (DNA) and found that
textiles woven with a double-helix structure can help overcome
this challenge.
The team has further developed a flexible piezoresistive
sensor to detect a human pulse. The sensor responds swiftly,
recovers quickly after being pressed and its signal is stable.
Led by Professor Hu Jinlian of the Department of Biomedical
Engineering and director of the Laboratory of Wearable Materials
for Healthcare at CityU, the researchers now hope it can be
introduced to the growing medical and healthcare market.
