Portable sensing and imaging : towards Portable Healthcare
Advances in medicine and technology are opening a new era of portable healthcare. Together with health apps, wearable/portable health monitoring systems are targeting medical diagnosis or health and wellness. The development of Wearable Health Monitoring Systems (WHMS) has been motivated mainly by increasing healthcare costs and by an aging world population. Optical techniques are widely used in clinical settings and in biomedical research to interrogate bio-molecular interactions and to evaluate tissue dynamics. Miniature integrated optical systems for sensing and imaging can be portable, enabling long-term imaging studies in living tissues. Fluorescent dyes are frequently used to mark biological samples, and track tissues, cells and individual molecules. In the lab, fluorescence is used to understand physiology and develop new cures to common diseases. In the clinic, fluorescence is used to diagnose health conditions and to evaluate treatments. Translating fluorescence imaging to portable healthcare systems will help us take better care of ourselves.
This seminar will review fundamental properties of fluorescence, tissue absorption and scattering and show how these can be used to track vital signs and provide wellness indicators during a physical activity. We will review examples of portable imaging systems in rapid disease diagnosis, and in health monitoring.
