Raynaud syndrome is a medical condition in which there are episodes of reduced blood flow, usually in the fingers and toes. The episodes result in the affected part turning white and then blue. Often there is numbness or pain. And as blood flow returns, the area turns red and burns.

About 4% of the world population is estimated to suffer from this disease, yet there is no cure for it. The main way of dealing with it is to avoid conditions that could potentially trigger a crisis - something easier said than done.

One goal of this project is to enable early detection of Raynaud's crises through the simultaneous monitoring of temperatures at the level of the fingers and wrist. The idea is that the temperature imbalance could be a foreshadowing sign of an imminent crisis.

Another goal is to create a platform to gather data in real-life settings. This is relevant as this disease has been studied so far in artificial lab conditions: by putting hands in an ice bucket.
