Researchers have created a ‘smart T-shirt’ that monitors the wearer’s respiratory rate in real time. And the key to this T-shirt is an antenna sewn in at chest level, which is made of a hollow optical fiber coated with a thin layer of silver on its inner surface. The fiber’s exterior surface is covered in a polymer that protects it against the environment. As the wearer breathes in, the smart fiber senses the increase in both thorax circumference and the volume of air in the lungs. This innovation paves the way for manufacturing clothing that could be used to diagnose respiratory illnesses or monitor people suffering from asthma, sleep apnea, or chronic obstructive pulmonary disease.
