| 摘要 |
An article of apparel such as sportswear whose outer surface exhibits a chromatic pattern related to thermal variations in the body of the wearer. The fabric of the garment is tailored to make direct contact with the skin of the wearer at different body sites. Integrated with the fabric or portions thereof are cholesteric liquid crystals. These are subjected to heat energy emanating from the skin of the wearer and therefore to variations in temperature that depend on the amount of body heat being dissipated in the area of contact. Because these liquid crystals have temperature-sensitive chromatic properties, the color pattern displayed by the garment undergoes changes in the course of wear.
