Overview
Connected medical devices are one of the fastest growing segments within IoT. Digital stethoscopes electronically amplify body sounds by converting acoustic waves to electrical signals. These digital signals can be graphically analyzed and wirelessly transmitted over the internet to support remote diagnosis.
