Sensor-laden vest continuously monitors its wearer’s lungs

Ordinarily, the lung perform of sufferers with respiratory issues is monitored by way of a stethoscope, throughout a go to to a clinic. An experimental new vest, nevertheless, can do the identical job all through the day, wherever its wearer goes.

Known because the Pneumo.Vest, the wearable is being developed as a part of the M³ Infekt project, which includes 10 branches of Germany’s Fraunhofer analysis group. The technology is presently aimed primarily at Covid-19 sufferers, though it might actually be utilized to different respiratory situations.

Incorporated into the back and front of the vest are a number of piezoceramic acoustic sensors, which individually detect even the smallest of noises produced by the lungs. Because the situation of every sensor (relative to the lungs) is already recognized, it is attainable to find out the place throughout the lungs every noise is coming from.

Custom software data and analyzes all of the sensor readings, and proceeds to supply a picture of the lungs during which problematic areas are highlighted. That picture might be considered on a linked cell machine, and will even be remotely accessed by way of a safe server on the web. This implies that sufferers might conceivably be monitored whereas in their very own houses, over prolonged durations of time.

“Pneumo.Vest is not looking to make the stethoscope redundant and does not replace the skills of experienced pneumologists,” stated project supervisor Ralf Schallert. “However, auscultation or even CT scans of the lungs only ever present a snapshot at the time of the examination. Our technology provides added value because it allows for the lungs to be monitored continuously.”
