Description

technical field [0001] The application belongs to the technical field of functional fabrics, and in particular relates to an adjustable temperature flexible thermoelectric device and its preparation method and application. Background technique [0002] Different kinds of functional fabrics have been developed in the prior art based on the human body's heat balance modes of heat radiation, heat convection, heat conduction, and sweat evaporation. These fabrics can realize the thermal management of the human body to a certain extent, but under extremely complex conditions, such as severe cold or hot summer, there are still many limitations in achieving warmth or cooling only by passive regulation of the fabric, and it is often impossible to make the human body comfortable. Effect. [0003] The thermoelectric devices currently provided are mainly based on non-bendable and brittle ceramic substrates, which are only suitable for industrial use. However, to apply to textiles or th...
