What is IoT in Healthcare?
In healthcare, IoT (often called the Internet of Medical Things, IoMT) encompasses any connected medical devices and sensors that collect and exchange health-related data. These devices range from consumer-grade wearables (smartwatches, fitness trackers) to clinical equipment (wireless ECG patches, smart infusion pumps)mckinsey.com. For example, the IoT can include continuous glucose monitors and heart-rate sensors that automatically upload data to a cloud platform. Gartner describes IoT as “a system of wireless, interrelated, and connected digital devices that can collect, send, and store data over a network” – and in healthcare these devices gather vital signs or treatment data without user intervention.
IoMT often involves multiple technology layers. According to industry research, the IoT value chain in healthcare has five key layers: devices, connectivity, data, applications, and servicesalleima.com. - Device layer: medical sensors, microchips, and transmitters (for example, the actual sensor wire in a continuous glucose monitor). - Connectivity layer: networking infrastructure (Wi-Fi, 5G, Bluetooth, cloud platforms) that transmits data from devices to servers. For instance, an insulin pump may send data over a secure Wi-Fi link to a hospital system. - Data layer: storage and processing of incoming data (often in cloud databases); this includes cleansing, integration with other data sources, and analysis. - Applications layer: software platforms and apps that clinicians or patients use to view and interact with the data – for example, a mobile app that alerts a doctor if a patient’s blood pressure reading is abnormal. - Services layer: supporting services (analytics, maintenance, training) and external partners that enable the IoT solution.
In sum, an IoT healthcare solution typically works as follows: device collects patient data → network securely transmits the data → platform stores and analyzes it → applications deliver actionable insights (alerts, dashboards) to providers or patients. This layered view helps implementers plan each step and ensure reliability and compliance.
Key Applications of IoT in Healthcare
