Comfit develops vital signs and activity monitoring devices for elderly, discharged patients and health conscious people. By integrating IOT (Internet of Thing) technologies, we provide vital signs and activity tracking, cloud storage, retrieval and mobile APP notification in our solution. "Elderly Potential Fall Warning, Fall Detection and Vital Sign Monitoring Smart Clothing" is under development. Vital signs (e.g. ECG, heart rate, blood pressure change and SpO2) and body posture are measured. The measured data is not only summarised to the user but their family doctors for reference. With appropriate algorithm, the possibility of potential fall and fall detection can be calculated. Further down the road, machine learning will be used to analyse the data collected to help on early detection of cardiovascular diseases.
