Researchers at Northwestern University have made a groundbreaking discovery in healthcare technology with the development of wearable devices that continuously monitor the sounds produced by the human body. These soft, adhesive devices adhere to a patient’s skin and utilize two advanced digital microphones to capture and analyze internal and external body sounds, such as breathing patterns, heartbeats, and digestive processes.
Unlike conventional stethoscopes, which require physicians to manually listen to specific points on the body, these devices use an innovative algorithm to distinguish between external and internal sounds. Furthermore, the algorithm accounts for ambient noises commonly found in hospital settings, ensuring accurate readings even in noisy environments.
Led by Dr. Ankit Bharat, the team conducted extensive clinical research, involving 55 adult subjects (including individuals with chronic lung diseases) and 15 premature babies experiencing respiratory and intestinal motility disorders. The devices demonstrated clinical-grade accuracy and delivered entirely new functionalities.
By continuously monitoring lung sounds in real-time, healthcare professionals can evaluate the effectiveness of medications or treatments and personalize healthcare plans for individual patients. The devices also provide spatial mapping of the lungs, allowing simultaneous monitoring and comparison of different regions. This innovative technology acts as the equivalent of having multiple highly trained doctors using their stethoscopes simultaneously, generating a continuous dynamic assessment of lung health.
The devices, measuring 40mm x 20mm x 8mm, encapsulate various components, including a flash memory drive, battery, Bluetooth technology, accelerometers, and miniaturized microphones. These components work in cohesion to map airflow in the lungs, track changes in cardiac rhythm, and monitor the movement of food, gas, and fluids through the intestines.
For premature babies, the devices are placed beneath the suprasternal notch at the base of their throats or on the right and left chest. In these positions, the devices enhance the detection of apneas and enable clinicians to promptly identify possible pathologies requiring immediate intervention. Placing the device on a baby’s abdomen allows for the monitoring of digestion issues, intestinal dysmotility, and obstructions.
The non-invasive and continuous monitoring capabilities of these wearable devices offer an array of benefits. Data can be collected without disturbing the babies, allowing for seamless monitoring and improved patient experiences. By monitoring noise levels around babies, healthcare professionals can take immediate action to address any sources of stressful auditory stimuli, promoting healthy growth and development.
This groundbreaking research, published in the journal Nature Medicine, revolutionizes the way body sounds are monitored and opens the door for personalized healthcare with real-time, accurate data collection.
