1. Understanding Wearable IoT for Healthcare

What Defines IoT Wearables?
IoT-based wearables are sensor-embedded devices that collect health data—such as heart rhythms or glucose levels—and transmit it wirelessly via BLE, Wi-Fi, or cellular networks to apps or cloud platforms. These systems enable real-time, remote patient monitoring and advanced analytics.

Continuous Glucose Monitoring (CGM)
CGMs revolutionize diabetes care by providing continuous glucose data. Devices like FreeStyle Libre and Eversense are FDA-approved and deliver real-time blood sugar insights directly to mobile apps.
Injectable and Patch-Based Glucose Sensors
Newer non-invasive solutions such as lab-on-a-patch and optical glucose sensors are emerging, minimizing or eliminating the need for finger-stick tests.
Wearable ECG Patches
Modern ambulatory ECG patches are:
-
Compact & lightweight for patient comfort.
-
Water-resistant for daily activities.
-
Multi-lead capable, giving cardiologists richer data.
-
Cloud-integrated for real-time analytics.
2. Use Cases & Benefits of ECG Patches and CGMs

Real-Time Cardiac Monitoring
ECG patches continuously record cardiac activity, detect arrhythmias, and enable early intervention. Their integration with predictive AI algorithms enhances risk detection.

Accurate Glucose Management
CGMs reduce reliance on finger pricks and allow patients to track and adjust lifestyles in real time. Alerts warn about hypo/hyperglycemia, preventing hospitalizations.
Preventive Healthcare & Predictive Insights
When paired with predictive analytics tools (see TechOTD’s blog), wearables anticipate health risks, giving doctors the chance to act before an emergency arises.
ICU & Critical Care Applications

Advanced skin patches can now monitor multiple biomarkers—helping ICU teams optimize drug dosages and monitor sepsis patients in real time.
Edge & 5G-Enabled Monitoring
Integration with 5G and edge computing ensures ultra-low-latency alerts, critical for conditions like cardiac arrest or sudden diabetic events.
