Abstract

Wearable devices that gather physiological information are highly demanded for bedside monitoring in hospitals, telenursing for elderly people living alone at home, and long-term health assessments to predict and prevent adult diseases. Against this background, we have developed an ultra-small laser blood flowmeter (2 mm wide × 3 mm long × 1.5 mm thick) that permits real-time monitoring of capillary microcirculation. This paper describes the measuring principle, fabrication method, and experimental results of the integrated micro blood flowmeter having a distributed feedback laser diode with a wavelength of 1.31 μm and an edge-illuminated photodiode.
