Wearable blood flowmeter appcessory with low-power laser Doppler signal processing for daily-life healthcare monitoring

K Kuwabara et al. Annu Int Conf IEEE Eng Med Biol Soc. 2014.

Abstract

A new appcessory for monitoring peripheral blood flow in daily life consists of a wearable laser Doppler sensor device and a cooperating smart phone application. Bluetooth Low Energy connects them wirelessly. The sensor device features ultralight weight of 15 g and an intermittent signal processing technique that reduces power consumption to only 7 mW at measurement intervals of 0.1 s. These features enable more than 24-h continuous monitoring of peripheral blood flow in daily life, which can provide valuable vital-sign information for healthcare services.
