Walk through a modern hospital floor, and nearly everything is transmitting data. Infusion pumps report dosing in real time, patient monitors stream vitals to central stations, and wearable sensors track movement long after discharge. A handful of companies build the infrastructure behind that constant flow of information.
Healthcare’s Internet of Things market has matured well beyond pilot projects. Established medical device manufacturers now compete alongside cloud providers and specialized digital health firms, each contributing a different layer of the connected care stack.

Philips
Philips builds connected patient monitoring systems designed to follow a patient from hospital admission through home recovery. Its wearable biosensors and interoperability platforms aim to close the gap between inpatient monitoring and post-discharge care, a transition where many complications historically went undetected.
GE HealthCare
GE HealthCare’s portfolio spans imaging, healthcare IT, and patient monitoring, with millions of connected devices operating across its global installed base. The company’s connected imaging systems feed data directly into hospital IT infrastructure, supporting both diagnostic workflows and equipment utilization tracking.
Siemens Healthineers
Siemens Healthineers frames its digital portfolio as part of a broader strategy to digitalize healthcare and improve both clinical and operational efficiency. Its connected imaging and diagnostic equipment integrate with enterprise services designed to reduce downtime and support remote equipment servicing.
Medtronic
Medtronic combines medical science, data, and AI across a device portfolio that includes connected implants and diabetes management technology. Its insulin pumps and continuous glucose monitoring integrations generate constant data streams that support automated insulin delivery decisions.
Abbott
Abbott’s connected cardiac devices and glucose monitoring systems, including its FreeStyle Libre platform, represent some of the highest-volume consumer-facing healthcare IoT deployments currently in use. Millions of people worldwide now wear Abbott glucose sensors that transmit readings directly to smartphone apps.
Dexcom
Dexcom specializes almost exclusively in continuous glucose monitoring, competing directly with Abbott in a market built entirely around real-time connected data. Its sensors transmit readings every few minutes, giving patients and clinicians a continuous picture rather than isolated fingerstick measurements.
Honeywell
Honeywell applies its industrial IoT expertise to hospital infrastructure, offering asset tracking and connected monitoring solutions that help facilities locate equipment and manage building systems. This operational layer often goes unnoticed by patients but matters significantly to hospital efficiency.
Microsoft and Amazon Web Services
Neither Microsoft nor AWS manufactures medical devices, but both provide the cloud infrastructure, IoT analytics tools, and security frameworks that connected medical device companies build on. Their role is foundational rather than clinical, supplying the compute and storage layer beneath most healthcare IoT platforms.
Masimo
Masimo built its reputation on pulse oximetry and has expanded into broader connected monitoring and wearable technology. Its sensors are widely used in hospital settings and increasingly appear in consumer wearables through licensing partnerships.
Baxter
Baxter connects infusion pumps and other hospital technologies to centralized monitoring systems, reducing manual programming errors and giving nursing staff visibility into medication delivery across multiple patients simultaneously.
Biofourmis
Biofourmis focuses on remote monitoring and digital biomarkers, using wearable sensors combined with AI analysis to detect early signs of clinical deterioration in patients recovering at home. Its technology supports hospital-at-home programs that have grown significantly in recent years.
How Healthcare IoT Companies Actually Create Value
Connected devices create value primarily by enabling earlier intervention. A continuous glucose monitor can flag a dangerous trend hours before a scheduled fingerstick test would catch it. A connected infusion pump can prevent a dosing error before it happens rather than requiring manual double-checks.
| Value Driver | Practical Example |
|---|---|
| Earlier intervention | CGM alerts before symptoms appear |
| Reduced manual monitoring | Automated vital sign transmission |
| Asset utilization | Equipment tracking reduces idle inventory |
| Remote care | Hospital-at-home vital monitoring |
| Predictive analytics | Deterioration risk scoring |
| Workflow improvement | Fewer manual data entry steps |
The Biggest Challenges Facing Healthcare IoT
Cybersecurity remains the most persistent concern, since every connected device represents a potential entry point into hospital networks. Interoperability compounds the problem, as devices from different manufacturers often use incompatible data formats that require additional middleware to reconcile.
Regulatory requirements add complexity for companies bringing new connected devices to market, particularly when software updates could affect a device’s cleared or approved status. Data overload is a less discussed but equally real problem: continuous monitoring generates far more data than clinical staff can review manually, making alert fatigue a genuine patient safety risk when systems generate too many low-value notifications.
Connectivity gaps in rural areas and patient privacy concerns round out the list of practical barriers that continue to slow full-scale adoption despite the technology’s clear potential.
Choosing Between IoT Vendors
Health systems evaluating connected device partners typically weigh a few practical factors beyond brand recognition. Integration compatibility with existing EHR and monitoring infrastructure often matters more than any single device’s individual feature set, since a best-in-class sensor that cannot communicate with the rest of a hospital’s systems creates more work than value. Total cost of ownership, including maintenance, battery replacement, and software licensing over several years, frequently outweighs the initial purchase price in long-term budgeting decisions.
Vendor support and update cadence deserve equal attention, particularly for devices with direct patient safety implications. A connected infusion pump or cardiac monitor that goes unpatched for security vulnerabilities poses a very different risk profile than a general-purpose office IoT sensor, which is why many hospital procurement teams now include cybersecurity review as a formal step before any new connected device reaches clinical deployment.
