A Novel 500 samples/sec 4 by 4 Photoplethysmography (PPG) Array Based Cosmetic Chip: Design

摘要

Microcirculatory dysfunction plays a key role in the p a t h o - p h y s i o l o g y o f v a r i o u s d i s e a s e s t a t e s . The m icrocirculation in the skin is in a rather complicated. With technical advances, microcirculatory monitoring nowadays becomes more and more available for application in clinical practice. The proposed cosmetic chip platform based on the photoplethysmography (PPG) is a simple and low-cost optical technique that can be used to detect blood volume changes in the micro-vascular bed of tissue.
