The wearable medical device market has expanded exponentially in recent years, and is only expected to continue growing with time as technology advances. Many devices use sensors placed on the body to transmit data to either remote detectors or smartphone applications. The resulting data can either be used by the patient or a physician to guide patient care. A major benefit to these devices is their ability to reduce healthcare costs by exploiting preventative healthcare and modern drug delivery systems. The information below provides a brief overview of some of the recently introduced innovative wearable medical devices.
