Integrating Sphere Finger-Photoplethysmography: Preliminary Investigation towards Practical Non-Invasive Measurement of Blood Constituents
The aim of this study was to compare conventional photoplethysmography (PPG) in a finger with PPG using an integrating sphere (ISPPG) to enhance scattered light collection. Two representative wavelengths were used; 1160 nm, a window through the absorption spectra of water and alcohol, and 1600 nm around where water absorption is high and there is an absorption peak of blood glucose. Simultaneou...
متن کاملSide-scattered finger-photoplethysmography: experimental investigations toward practical noninvasive measurement of blood glucose.
The aim of this study was to discover a simple/convenient geometrical arrangement of radiation sources and detector to acquire finger-photoplethysmograms (PPGs) with wavelength regions of blood glucose (BGL) absorption, toward practical noninvasive BGL measurement. First, we compared PPGs with three wavelengths: 808 nm (without water absorption), 1160 nm (with weak water absorption), and 1600 n...
متن کاملGrid-Enabled Non-Invasive Blood Glucose Measurement
Earth and life sciences are at the forefront to successfully include computational simulations and modeling. Medical applications are often mentioned as the killer applications for the Grid. The complex methodology and models of Traditional Chinese Medicine offer different approaches to diagnose and treat a persons health condition than typical Western medicine. A possibility to make this often...
متن کاملAdaptive Non-invasive Blood Pressure Measurement
In this paper oscillometric method is used to develop an adaptive non-invasive blood pressure measurement system. To overcome the drawback of conventional oscillometric method an algorithm is developed. During the time of deflation and inflation process the step size of pressure pumped and released using pump and valve respectively is varied adaptively by continuously monitoring the feedback wh...
متن کاملIntegrating Sphere Functionality: The Scatter Transmission Measurement
The integrating sphere is a simple, yet often misunderstood spectrophotometer accessory for measuring optical radiation. The function of an integrating sphere is to spatially integrate radiant flux in scatter transmission and diffuse reflectance sample measurements. Before one can optimize a sphere design for a particular application, it is important to understand how the integrating sphere wor...
