Expertise
Biography
Andrew's lab recently developed a flexible, chalk-based coating which can be added to fabrics that has been found ittoreduced the temperature underneath clothes by up to 15 degrees compared to untreated fabrics.
In 2023, she led a team that solved the 80-year old quest to make a synthetic textile modeled on polar bear fur.
She is a David and Lucile Packard Foundation Fellow, a National Academy of Sciences Kavli Fellow, a L’Oréal USA For Women in Science Fellow, and was named as one Forbes’ magazine “30 Under 30” Innovators in Energy.

Researchers at the University of Massachusetts Amherst have developed a flexible, chalk-based coating which can be added to fabrics. ... “We start with your cotton T-shirt… and we just apply this coating on either one or both faces of the fabric,” Trisha L. Andrew, a chemist and materials scientist at UMass, told CNN. “The coating is entirely surface level. It does not penetrate or change the cotton fibers."

Who hasn’t wished for clothing that stays cooler during the sultry days of summer? Thanks to the work of Trisha L. Andrew, professor of chemistry, chemistry graduate student Evan D. Patamia and undergraduate Megan K. Yee, we may all be a little closer to comfort. The team has devised a durable chalk-based fabric coating that cools the air underneath the treated fabric by up to 8 degrees Fahrenheit.
Why Does the Same Temperature Feel Hotter or Colder in Different Places?

Trisha Andrew, professor of chemistry at UMass Amherst, discusses how fabrics behave differently in an article about why the same temperature can feel different. “Unlike synthetics, which are mostly plastics, natural materials actually absorb a small amount of moisture, drying out the air in between layers so that you have less of a conductive channel to radiate heat away from your body,” she says.

Wearable electromechanical sensors are essential to improve health monitoring and off‐site point‐of‐care applications. However, their practicality is restricted by narrow ranges of detection, failure to simultaneously sense static and dynamic pressures, and low durability. Here, an all‐fabric pressure sensor with high sensitivity in a broad range of pressures, from subtle heart pulses to body posture, exceeding that of previously‐reported sensors is introduced.
Solar thermal textiles for on-body radiative energy collection inspired by polar animals

Humans use textiles to maintain thermal homeostasis amidst environmental extremes but known textiles have limited thermal windows. There is evidence that polar-dwelling animals have evolved a different mechanism of thermoregulation by using optical polymer materials to achieve an on-body “greenhouse” effect. Here, we design a bilayer textile to mimic these adaptations. Two ultralightweight fabrics with complementary optical functions, a polypropylene visible-transparent insulator and a nylon visible-absorber–infrared-reflector coated with a conjugated polymer, perform the same putative function as polar bear hair and skin, respectively.
