Graduate students Ali Kiaghadi and S. Zohreh Homayounfar, with their professors Trisha L. Andrew, a materials chemist, and computer scientist Deepak Ganesan, will introduce their health-monitoring sleepwear “phyjamas” at the Ubicomp 2019 conference this week in London, U.K.
As Andrew explains, “The challenge we faced was how to obtain useful signals without changing the aesthetics or feel of the textile. Generally, people assume that smart textiles refer to tightly worn clothing that has various sensors embedded in it for measuring physiological and physical signals, but this is clearly not a solution for everyday clothing and, in particular, sleepwear.”
“We expect that these advances can be particularly useful for monitoring elderly patients, many of whom suffer from sleep disorders,” says Andrew. “Current generation wearables, like smartwatches, are not ideal for this population since elderly individuals often forget to consistently wear or are resistant to wearing additional devices, while sleepwear is already a normal part of their daily life. More than that, your watch can’t tell you which position you sleep in, and whether your sleep posture is affecting your sleep quality; our Phyjama can.”
This work was enhanced by Ganesan and Andrew’s affiliation with UMass Amherst’s Institute of Applied Life Sciences (IALS), which focuses on translating life science research into products that improve human health. Director Peter Reinhart at IALS says, “It’s exciting to see the next generation of wearable technology that is zero effort and addresses the issue of comfort and unobtrusiveness head-on. The data generated by fabric-based sensors have the potential to improve health and well-being, and could possibly contribute to the early diagnosis of multiple disorders.”
