By a News Reporter-Staff News Editor at Journal of Engineering -- A research team from National University of Singapore (NUS) has developed a soft, flexible and stretchable microfibre sensor for real-time healthcare monitoring and diagnosis. The novel sensor is highly sensitive and ultra-thin with a diameter of a strand of human hair. It is also simple and cost-effective to mass produce.

Wearable and flexible technology has gained significant interest in recent years, leading to tremendous progress in soft and wearable sensors. In tandem with this trend, microfluidic devices using conductive liquid metals have been increasingly employed as wearable pressure and strain sensors. However, current devices have various limitations - for instance, they may not fit well on the skin or are uncomfortable to wear.

“Our novel microfibre sensor can hardly be felt on the skin and conforms extremely well to skin curvatures. Despite being soft and tiny, the sensor is highly sensitive and it also has excellent electrical conductivity and mechanical deformability. We have applied the sensor for real-time monitoring of pulse waveform and bandage pressure. The results are very promising,” said Professor Lim Chwee Teck from the Department of Biomedical Engineering at NUS Faculty of Engineering, who is the leader of the research team.
