Description
Toru Shimuta and co-authors build a finger sensor that reads blood flow in small vessels. Their 2024 study uses light: green and near-infrared beams shine into the finger, and the returning pulse wave is recorded. Diabetes is known to starve the tiny vessels, yet no easy home gauge exists.
The team tested 25 patients with diabetes against 21 healthy adults. One width measure of the pulse ran smaller in the diabetes group. A timing gap between the green and infrared pulse peaks was also clearly larger. The authors say a ring-worn version could let patients track their small-vessel flow at home, day by day.
