Wearable Technology

• a wearable computer in the form of a wristwatch that provides a touchscreen interface, runs a mobile operating system, and connects to your smartphone.

• Smartphone Notifications: Displays incoming text messages, social media alerts, emails, and phone calls without requiring you to pull out your phone. 

• Health and Fitness Tracking: Utilises built-in sensors to monitor your daily step count, heart rate, sleep quality, and blood oxygen levels (SpO₂). 

• Communication: Many mid-range and premium models include a built-in microphone and speaker, allowing you to answer Bluetooth calls directly from your wrist. 

• App Support & Customisation: Features dedicated app stores to download tools like navigation maps, music controllers, and custom digital watch faces.

• Connectivity: Pairs with your phone via Bluetooth or Wi-Fi. Some high-end cellular models use an integrated electronic SIM (eSIM) to make calls and stream music independently without a smartphone nearby.

An Oura Ring (properly stylised as Ōura) is a premium, lightweight smart ring worn on the finger to track your sleep, physical activity, and overall recovery.

Instead of using a screen like a smartwatch, it packs advanced health sensors into a seamless titanium or ceramic band. It works invisibly in the background, syncing your health biometrics via Bluetooth to the Oura App on your iPhone or Android phone.

A continuous glucose monitor (CGM) is a type of wearable technology. It is a specialised, medical-grade wearable device designed to track a person's blood sugar levels in real-time throughout the day and night.

Unlike consumer wearables like smartwatches or fitness rings that sit purely on top of the skin, a CGM is a biowearable. It uses a tiny, flexible sensor wire inserted just under the skin (usually on the back of the arm or the abdomen) to measure glucose levels in the fluid between your cells.

📟 How It Works as Wearable Tech

• The Sensor: A small wearable patch containing a microscopic filament that stays in place for 10 to 14 days.

• The Transmitter: A small, reusable or integrated piece attached to the sensor that beams data wirelessly via Bluetooth.

• The Receiver: A smartphone app (such as the Dexcom App or FreeStyle Libre App) or a dedicated handheld monitor that displays live readings, historical trends, and predictive alerts.

• a wearable electronic device that tracks physical activity, health metrics, and sleep patterns 

Meta glasses are a line of voice-controlled smart eyewear developed by Meta (often in partnership with iconic brands like Ray-Ban) that combine everyday style with hands-free wearable technology. They are designed to let you capture content, listen to audio, and interact with artificial intelligence without needing to pull out your smartphone. 

A pacemaker is technically classed under the broader umbrella of wearable technology, but it belongs to a specialized, high-risk subcategory known as implantable wearables or internal wearables.  A traditional pacemaker shares the exact same core architecture as a modern consumer wearable: 

• Sensors: It continuously monitors biometrics (your heart's electrical rhythm). 

• Processor & Computer Logic: It analyzes that real-time biological data to make instantaneous decisions. 

• Actuator/Output: Instead of sending a push notification to a screen, it delivers a microscopic electrical pulse to keep the heart beating at a safe rate. 

• Wireless Connectivity: Modern pacemakers utilize wireless telemetry or Bluetooth to transmit data securely to a smartphone app or a physician's portal.
