Design of Multi-Wavelength Optical Sensor Module for Depth-Dependent Photoplethysmography
The multi-wavelength photoplethysmography sensors were introduced to measure depth-dependent blood volume based on that concept that the longer the light wavelength, the deeper the penetration depth near visible spectrum band. In this study, we propose an omnidirectional optical sensor module that c...
