Miniature wearable acoustic sensor 'can monitor heart rates'

17 November 2016

A tiny, wearable acoustic sensor has been developed that has the potential to aid the monitoring of users' cardiovascular health.

Researchers from the University of Colorado at Boulder and Northwestern University have created the new device, which captures physiological sound signals from the body through vibrations, and is also capable of recognising spoken words.

Its physical properties are well-matched with human skin and can be mounted on nearly any surface of the body, with a weight of less than one-hundredth of an ounce meaning it can be worn discreetly.

The device is also capable of integrating electrodes to record electrocardiogram signals that measure the electrical activity of the heart, as well as electromyogram signals to monitor muscles activity.

Theoretically, a wireless version of this sensor could be used to remotely monitor heart health, allowing doctors to make diagnoses or check on a patient's condition.

Jae-Woong Jeong, an assistant professor at the University of Colorado at Boulder and one of the leaders of this study, said: "It is very comfortable and convenient - you can think of it as a tiny, wearable stethoscope."
