A flexible and wearable intelligent health monitoring system with novel fiber material
As a new type of portable electronic device, flexible and wearable electronic system has broad applications in human-machine interaction, health monitoring, and medical care. Wearable electronic systems require a material that is strong to ensure durability and stability, and a wide range of strain to expand the applications. Fibrous material is promising as an essential component of high-performance wearable electronic devices. However, it remains challenging to manufacture fibrous materials with simultaneously high mechanical strength and tensile properties.
To solve this problem, professor Wang Xuewen from a team of Academics at Huang Wei in Northwestern Polytechnical University has developed a flexible and wearable intelligent health monitoring system. This intelligent "electronic clothing" can realize real-time monitoring of body tremors, pulses, breathing, gestures, and six kinds of human motion postures. The relevant results have been published in the International Authoritative Journal Advanced Materials.
Gao Jiuwei, PhD explained that the fiber material presents several advantages over traditional metallic materials and films, including low weight, high elasticity, and easy processing. "A conductive fiber sensor comprising of our novel fiber material as the inner core can demonstrate both high mechanical strength (≈17.6 MPa) and excellent tensile properties (≈700 percent), as well as ultra-broad operating range from 0.0075 percent to 400 percent," he adds.
The team, cooperating with professor Song Weitao from Beijing Institute of Technology, also implanted high-performance fiber strain sensors into clothes to manufacture a flexible and wearable intelligent health monitoring system. "It is amazing that our sensor can monitor various human motions and postures in real time, which will help promote the development of health assessment and disease diagnosis technologies with intelligence, remoteness, efficiency, and precision," professor Wang said.
Professor Wang's team has long been focusing on researching flexible sensing materials as well as exploring their applications in strategic emerging fields, such as health care and human-machine interaction. They are investigating novel ideas to improve the efficiency and quality of medical information transmission and processing through intelligent sensing systems.
