BATON ROUGE – An academic at Louisiana State University (LSU) has developed a woolly hat for infants that reportedly changes colour based on body temperature.

Sibei Xia, an assistant professor at LSU’s Department of Textiles, Apparel Design and Merchandising, used thermochromic yarn – which changes colour when exposed to heat - during the knitting process to gauge whether it could be a barometer of whether a baby has a fever.
