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.
Body Surface Area
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.

Current Options for Amputees
There are some treatment options available including anti-perspirant sprays, Botulinum toxin, medication, electrical stimulation and surgery. However, these treatments often aren’t successful and may cause further side effects.
