A highly sensitive contact type fiber Bragg grating dynamic pressure sensor was designed to achieve the detection of pulse wave information in this paper. The sensitivity and frequency range of the sensor were analyzed by using the finite element method. A sensing system based on the fiber Bragg grating pressure sensor and interferometric wavelength demodulating based on phase generated carrier (PGC)...
In this paper, we propose a novel non-contact method to detect the pulse information from the radial artery using the infrared sequence images. First, a ROI (region of interest) can be located on the radial artery by the infrared imaging system because of its higher temperature than surrounding tissue. Then, a short time of AVI video of the radial artery is recorded and the area of the ROI is calculated...
The acquisition and application of people's various physiological and psychological states will play a very important role in future smart society. In this paper, body sensor network is used to perceive human physiological parameters, especially human skin resistance in and out of adjacent fingers and the pulse information in ulnar-sided position on the right hand. Then the feature combination which...
