Investigations for the development of smart trousers for paraplegic wheelchair users. Part 2 – Development of a test prototype of smart heating trousers

Abstract

The main objective of this research was to develop smart trousers for paraplegic wheelchair users to improve the thermal comfort of their lower extremities when exposed to cold environments. In this part of the research, a test prototype of smart heating trousers was developed and tested on the thermal manikin. The development of the test prototype of the smart heating trousers is based on the design recommendations explored in the first part of this paper. The design recommendations relate both to the development of a trousers pattern design for the sitting posture of wheelchair users and the possibility of integrating electrical components into the trouser design, as well as the development of a smart heating system that provides safety for the wearer of the trousers. The results of this part of the research show that the developed smart heating trousers can improve the thermal insulation of the legs and the thermal comfort of the wearer. This is ensured by a carefully planned and safe algorithm that automatically regulates the temperature of the microclimate inside the trousers.
