Smart Shirt Montiors Breathing Contact-Free

A smart shirt with an oxygen sensor built in offers a non-contact way to monitor respiration rates in real-time. The lightweight T-shirt is embedded with a spiral antenna made out of a hollow optical fibre and coated with a layer of silver. The antenna, which sits at chest level, collects respiratory data by tracking the amount of air in the lungs as well as the circumference of the thorax. That information is then transmitted via the same antenna to a device operating within the antenna’s frequency.
