Wearable sensing devices for unobtrusive biomedical monitoring

Wearable sensing devices suitable for continuous and stable biomedical monitoring are presented. Their advantages are biocompatibility and compactness for easy wearing. One device is a T-shirt-type heart rate or electrocardiogram sensor that features a biocompatible fabric electrode called “hitoe”. Another is a wearable blood flowmeter whose main part is as small as a fingertip. Test results point to some interesting applications, such as monitoring mental or physical states.
