TP27; Color-changing fabric system with temperature control is designed through textile design and electronic technology. The system inserts a conductive fabric inside a fabric coated with thermochromic powder. A temperature control system is constructed to adjust the current to raise the temperature of conductive fabric to the active point of thermochromic powder and keep the temperature in stable. Therefore, the fabric could sense the temperature and change colors. In order to achieve wearability, mobile power supply is selected and flexible sensor is adopted. Kalman filter is engaged in the proportion integration differentiation ( PID) control algorithm to reduce the interference of measurement noise. The experiment result shows that the proposed color-changing fabric system could reach the target temperature quickly and meet the design demands for color-changing.
