THE STETHOSCOPE GETS A “SMART” IOT UPGRADE
Engineers at John Hopkins University integrate AI, acoustics, and noise-canceling technology to modernize this humble medical device. The Internet of Things and advances in technology—among them higher-resolution imaging, device connectivity, miniaturized motion components, and 3D printing—are forcing several medical devices to upgrade. No device is free from the upgrade cycle, including the stethoscope. The stethoscope was designed and built by French physician René Laennec in 1816. When examining a patient, he decided to roll sheets of paper into a tube to amplify the chest sounds instead of placing his ear directly on the patient’s body.  Laennec’s initial prototype led him to devise the stethoscope, cementing his status as the father of auscultation.
