城大研發超級透氣穿戴式電子設備 助長期穩定監測生物信號

CityUHK develops super permeable wearable electronics for stable, long-term biosignal monitoring

Wearable electronics play a significant role in promoting health and fitness. Continuous
monitoring of physiological signals over a prolonged period is essential for gaining a
comprehensive perspective on an individual's overall health status and personalised
therapeutics. However, the long-term signal stability could be influenced by sweat or air
permeability.

Scientists at City University of Hong Kong (CityUHK) have developed super wearable electronics
that are lightweight, stretchable and increase sweat permeability by 4,000-fold, enabling
reliable long-term monitoring of biosignals for biomedical devices.
Led by Professor Yu Xinge in CityUHK’s Department of Biomedical Engineering (BME), the
research team has recently developed a universal method to creating these super wearable
electronics that allow gas and sweat permeability, and can provide continuous and stable
monitoring of vital signs without causing discomfort or signal disruption brought about by
perspiration.
The team has developed a fundamental methodology from materials processing, device
architecture and system integration for integrated permeable wearable electronics based on a
three-dimensional liquid diode (3D LD) configuration.

重要。然而，信號長期的穩定性會受汗液或空氣的透氣度影響。
香港城市大學（城大）科學家研發出輕便、可伸展，並將排汗度提高
4,000倍的超級穿戴式電子設備，有助生物醫學設備長期並可靠地監測
生物信號。

由城大生物醫學工程學系于欣格教授領導的研究團隊，最近開發出一
種通用技術以製造出透氣排汗的超級穿戴式電子設備，能持續及穩定
