A variety of unobtrusive wearable devices have been developed by different research teams as shown in Fig. 4 : the watchtype BP device [3] , clip-free eyeglasses-based device for heart rate and PTT measurement [37] , shoe-mounted system for the assessment of foot and ankle dynamics [53] , ECG necklace for long-term cardiac activity monitoring [54] , h-Shirt for heart rate and BP measurement [55] , an ear-worn activity and gait monitoring device [56] , glove-based photonic textiles as wearable pulse oximeter [57] , a strain sensor assembled on stocking for motion monitoring [58] , and a ring-type device for heart rate and temperature measurement [59] . ./cache/cord-010326-9xf2luzi.txt ./txt/cord-010326-9xf2luzi.txt
