Wearable small blood flow sensor

We have realized a small wearable blood flow sensor.

Peripheral blood flow reflects movement of the circulatory system and mental state, so it is expected to be applied to health promotion related to blood circulation, medical support, and entertainment fields.
This change in peripheral blood flow can be viewed in real time on a smartphone using a wearable compact blood flow sensor.
In addition, due to power saving, long-term continuous monitoring is possible while carrying.

Feature

Visualize changes in blood flow with a smartphone

By irradiating the skin surface with laser light, it is possible to visualize the trend of changes in peripheral blood flow from the frequency spectrum of the scattered light. Visualized information can be viewed in real time on a smartphone.

Compact and power saving

It is smaller and consumes less power than conventional blood flow meters, so long-term continuous monitoring is possible while being carried.

Easy acquisition of measurement data

The acquired blood flow data can be downloaded from a smartphone as a CSV file.

	Measurement item	Blood flow, reflected light amount, average blood flow

others

・The measured value fluctuates depending on the place and pressure where the sensor head is pressed. sensor head at constant pressure
must be in contact.
・Smartphone for installing visualization application is not included. Please prepare separately.
