“Researchers at the National Science Foundation Nanosystems Engineering Research Center for Advanced Self-Powered Systems of Integrated Sensors and Technologies (ASSIST) at North Carolina State University have developed wearable sensors that are powered by a patient’s body heat and can monitor the sound of a patient’s breathing,” said Krim, senior author of a paper on the work, in a statement. “Now we’ve developed an algorithm that can assess the onset time, pitch and magnitude (or volume) of wheezing sounds to give healthcare professionals information about the condition of the lungs. This information, in turn, can be used to help doctors make more informed decisions about diagnosis and treatment.” Thus far, Emrani and Krim have the sensors and the algorithm ready — their next step is to find a way to incorporate a smart device. “We’re currently weighing whether to modify the sensors so that they can run the algorithm and transmit only if there is a problem, or to maintain the current approach of having the sensor transmit all of the data so that the smart device runs the algorithm,” said Krim. “ASSIST is also working to develop sensors that can operate wirelessly, so that the sensors don’t need to be physically connected to the smart device.”
