IoT connects billions of devices through sensors and the cloud to generate massive amounts of data. This data can be used in healthcare applications like remote patient monitoring, clinical research, and supply chain management. By 2020, it is estimated there will be 31 billion connected devices generating large volumes of unstructured data. This will require innovations in sensors, networks, cloud computing, and analytics to extract value from the data while managing challenges of scale. IoT applications in healthcare promise benefits like reduced costs, improved treatment outcomes, disease management, and an enhanced patient experience.
