Method & Evidence

AimCan a textile material be engineered to adapt its thermal properties in response to physiological cues like sweat, thereby enhancing user comfort and reducing energy consumption for climate control?

MethodExperimental research and material development

ProcedureResearchers developed a bilayer material composed of a hygroscopic layer (polyethylene glycol and cellulose acetate) and a hydrophobic polymer (polyester). This bilayer was patterned with flap-shaped pores on a fabric surface. The material's response to simulated sweat and humidity was tested using a skin-simulating device to measure apparent temperature changes.
