  "textContent": "The same wireless technology that can track your cat or locate an item in a warehouse can also monitor your breathing. Researchers at Chalmers University of Technology, Sahlgrenska University Hospital and the University of Gothenburg, Sweden, now present a completely new method for measuring breathing movements in patients with impaired lung function. Using small, plaster-like tags, breathing can be analyzed in detail entirely contactlessly—in hospital or at home.",
