A specialized shoe insole engineered to maintain a constant foot temperature of 32C is currently in development at Maynooth University, offering targeted relief for individuals living with epidermolysis bullosa simplex.
The Mechanics of Friction Prevention
Caused by a missing protein that binds skin layers together, the condition triggers severe blistering during basic everyday activities like walking. The prototype counters this through an internal cooling fluid paired with a separate heat exchanger worn outside the shoe.
This mechanism addresses heat, moisture, and abrasion that causes painful blistering. Dr. Linzi Ryan, research lead at Maynooth University’s Department of Design Innovation, noted that the hidden nature of the condition frequently restricts patients from participating in normal social activities, such as walking to a bus with peers.
Real-World Relief for Families
The latest iteration of the device was recently demonstrated to Mark and Sophia Dawson, a Co. Meath family living with the condition.
Mark Dawson explained that the innovation provides critical relief for individuals who appear healthy on the outside but endure significant physical tolls from basic mobility. Debra, the national charity supporting the 300 people in Ireland affected by EB, collaborated through its expert panel to guide the project.
Funding and Medical Classification Aims
Fatma Ben Yousseff, head of research at Debra, described the device as a potential game changer that removes major barriers to daily movement, noting that some individuals previously resorted to placing frozen sanitary towels in their shoes to manage sweating.
The current development phase is receiving seed funding from Debra and EB Research in Austria. Researchers intend to pursue medical device classification to ensure broader accessibility for the affected community.
