Motion Responsive Sportswear is a research project conducted by Kerri Wallace, a textile designer from the UK. Her design uses "a correlation between heart rate and body temperature as a trigger for the visual representation of the activity level by changing the color pattern of sports apparel."

The sports wear is printed with temperature specific thermo-chromic and thermo-chromic liquid crystal inks which change colours with the change in the intensity of activity as well as in body temperature.
