Raynaud's Phenomenon

Raynaud’s Phenomenon (RP) is the term given to describe short periods of severely reduced blood flow in fingers and or toes, resulting in pain and numbness following exposure to a trigger stimulus such as cold temperature, emotional distress or vibration- as can be seen above. It most commonly affects fingers, but also other extremities (toes, nose), as a result of arterial constriction.

CTDRU is undertaking a project entitled: “Experimental Development of a Novel Technology to Alleviate the Symptoms of Raynaud’s Phenomenon”

The objective of the project is to create a glove that could be used by RP sufferers both indoor and outdoor., and create an understanding of material properties to determine the optimal combination, and even develop novel materials. This was to culminate in the production of a demonstrator which was comprised of a slim laminated wearable material with a performance capable of ameliorating RP (stage 1). The demonstrator would then form the basis for integrating intelligent feedback-controlled (or equivalent) heating system to apply heating optimally (sensibly) to target a reduction in RP (stage 2). Power was always a concern and therefore, the project envisaged requiring an integration of novel power scavenging, in order to prolong battery life. We would like to thanks the Raynaud’s and Scleroderma Association (RSA) for helping us appreciate the sufferers perspective, wants and needs.
