A wearable respiration monitor inspired by Shrinky Dinks offers a simple and affordable way to measure air intake.
Measuring the amount of air inspired by a patient can help monitor conditions like cystic fibrosis and warn of impending asthma attacks.
To offer a simple way to track air intake, the team from the University of California created a wearable sensor by applying a thin layer of metal to the Shrinky Dink material and then heat-shrinking it so it would corrugate. That film is then attached to a soft, bandage-like material that is applied to the patent between the ninth and tenth ribs and on the abdomen. By measuring the strain on the application areas, the sensor can track the wearer’s rate and volume of respiration, even as the wearer is walking around and going about their daily activities.
