Excessive sweat is not only a problem for active amputees. Over the course of a normal day, heat and moisture can build up, becoming a constant problem for all amputees.
The human body produces sweat to regulate temperature when hot, however sweat is a major issue for amputees. Not only do amputees have a greater need to regulate their temperature as they require greater effort to walk, but there is a compromised ability to cool due to reduced body surface area which is compounded by current sockets and liners which act as insulators.
Trans-tibial amputees expend 20-40% more effort to walk but at the same time, their body surface area is typically reduced by 10-15% which impacts cooling capacity.
