Collecting and analyzing various personal biological and environmental sensing data is important for various medical services, for example, lifestyle self-check support, personalized medical support and medical studies for the public purpose. We aim to deploy in 5 to 10 years and are studying on a physiological and environmental information processing(More)
This paper describes wireless wearable and ambient sensors that cooperate to monitor a person's vital signs such as heart rate and blood pressure during daily activities. Each wearable sensor is attached on different parts of the body. The wearable sensors require a high sampling rate and time synchronization to provide a precise analysis of the received(More)
We have developed a new method to estimate no only stress occurrence, but also various workplace stress types. The method relies on adaptive selection of physiological indices integrated into an intelligent multi-steps discrimination process. Preliminary results revealed the method promising to improve estimation accuracy of workplace stress types. The(More)
Blood pressure measurement methods used nowadays have considerable drawbacks, as non-invasive measurements are non-continuous while invasive measurements are confined to in-hospital use. In this paper, we expose our solution of a continuous, non-invasive blood pressure measurement method, using electrocardiogram (ECG) and photopletysmograph (PPG) as a basis(More)
