The high-tech vest monitors lung function


It is true that there used to be a summer camp for children with asthma called Camp Wheeze. It was in the San Francisco Bay Area, and that’s where a member of our team learned all about his asthma. But after their first year at camp, and after some suggestions from parents, the camp was renamed Camp Breathe Easy. If only the camp had access to these Pneumo Vest Project vests. They provide a non-invasive way to monitor lung function. Here’s more from Wearable Technology Insights:

As part of the Pneumo.Vest project, researchers from the Fraunhofer Institute for Ceramic Technologies and Systems IKTS in the Berlin office have developed a textile vest with integrated acoustic sensors, presenting a high-performance complement to the traditional stethoscope. Piezoceramic acoustic sensors have been incorporated into the front and back of the vest to record any noise produced by the lungs in the thorax, no matter how small. Software records the signals and amplifies them electronically, while the lungs are visually represented on a screen. Since the software knows the position of each individual sensor, it can assign the data to its precise location. This produces a detailed acoustic and optical picture of the ventilation situation of all parts of the lungs. Here’s what makes it so special: Because the system collects and stores data permanently, exams can take place at any time and in the absence of hospital staff. Pneumo.Vest also shows the condition of the lungs over a period of time, for example over the past 24 hours.

And if monitoring oxygenation levels is important to you, here’s a project that uses our Adafruit Feather nRF52840 Express and Adalogger FeatherWing, along with a fingertip pulse oximeter to record oxygen levels:
