Wearable stethoscope patch gets the goods on respiratory problems
While a stethoscope will tell you if someone has a respiratory ailment, it will only share that information in the few minutes it's being used by a trained physician. A new wearable device could paint a much bigger picture of the problem, by monitoring the patient's breathing for days at a time.
The device is just a few millimeters thick, and incorporates components such as a downward-facing unidirectional MEMS microphone, a microcontroller unit, a Bluetooth LE module, a flexible printed circuit board, and a lithium-polymer battery. Adhered to the skin on the patient's back (between their spine and one shoulder blade), the device continuously monitors the noises made by the person's lungs and the rest of their airways as they breathe. An experienced freelance writer, he previously obtained an English BA from the University of Saskatchewan, then spent over 20 years working in various markets as a television reporter, producer and news videographer.
