Most of the wearable devices in the market are consumer fitness tracker for recording heart rate, sleep behavior and step count etc. Even though some devices can monitor the blood pressure (BP), which only provide a snapshot measurement. They cannot serve as medical devices to perform long-duration and high accuracy monitoring of vital signs for daily-use, especially cardiovascular-related vital signs. It is important to measure BP continuously for nighttime monitoring and accurate diagnosis of different cardiovascular disease symptoms and vascular dementia for elderly. In view of this, CUHK team develops an unobtrusive health-monitoring system combining multimodality sensing and machine learning technologies by integrating novel sensor designs, signal generation and processing methods (included multi-wavelength photoplethysmogram and multi-sensor coordination) in a medical wearable platform, in order to achieve early detection of cardiovascular diseases, effective remote health monitoring and prevention of dementia for the elderly.

Work flow of cardiovascular-related vital signs using our MWPPG-based wearable device. (Our wearable device collects signals via user’s finger or wrist and then transmits signals to mobile terminal and data center to generate a personalized health report containing the readings of cardiovascular-related vital signs.)
Significance of 24-hour and night-tine blood pressure monitoring
Our innovative hardware design
Our high accuracy algorithm

Uniqueness and Competitive Advantages:

  • High accuracy
  • Comfortable, portable and elderly-friendly
  • Unobtrusive and undisturbed
  • Continuous and real-time monitoring of the cardiovascular-related vital signs (e.g., heart rate, blood pressure, breathing rate, and blood oxygen level)

Handheld High-Resolution Short-Wave Infrared Spectrometer

Spectrometers are widely used in many different aspects, such as food and environmental inspection etc. However, it is necessary to have a portable and high-resolution spectrometer for real-time on-site inspection at remote farm or factory. CUHK team invented two new technologies, which broke the traditional boundary. We develop a handheld high-resolution short-wave infrared (SWIR) spectrometer […]
