AI technology can now estimate blood parameters (like glucose, hemoglobin) and blood pressure (BP) without a traditional blood test, using skin-based sensors, cameras, and AI models. Here’s how:
1. AI for Non-Invasive Blood Testing Using Skin
🩸 Spectroscopy-Based AI Models
- Uses near-infrared (NIR) or Raman spectroscopy to analyze light reflections from skin.
- AI interprets glucose, hemoglobin, or cholesterol without a blood sample.
- Example: Biospectal uses AI to measure blood hemoglobin from skin.
📱 Smartphone Camera-Based AI
- Uses optical sensors (like those in smartwatches).
- AI detects color changes in the skin to estimate blood markers.
- Example: AnemoCheck estimates hemoglobin levels using a smartphone photo of fingernails.
2. AI for Blood Pressure (BP) Monitoring Without Cuff
📸 Camera-Based AI BP Measurement
- Uses PPG (Photoplethysmography) & AI to analyze skin color changes caused by blood flow.
- Smartphone cameras or webcams track tiny skin color variations.
- Example: Anura by Nuralogix estimates BP just from a 30-second selfie.
⌚ Smartwatches & Wearables
- Devices like Samsung Galaxy Watch, Apple Watch, and Fitbit use PPG + AI to estimate BP.
- AI continuously analyzes pulse transit time (PTT) to monitor BP.
🔬 Bioimpedance & Ultrasound Sensors
- AI-powered sensors track skin’s electrical properties to measure hydration and BP.
- Ultrasound patches use AI to detect arterial pressure without cuffs.
- Example: Aktiia Bracelet tracks BP 24/7.
3. AI for Glucose Monitoring Without Finger Pricks
🍬 Wearable AI for Non-Invasive Glucose Monitoring
- Uses electromagnetic waves or infrared light to estimate blood sugar through the skin.
- Example: Dexcom G7 & FreeStyle Libre use AI with continuous glucose monitoring (CGM).
📱 Smartphone-Based Glucose Detection
- AI models analyze skin properties to estimate glucose.
- Example: Google’s AI-powered GlucoWatch (under research) aims for non-invasive glucose tracking.
4. AI-Based Skin Sensors for Health Monitoring
🔬 Electromagnetic & Optical Sensors
- AI interprets electromagnetic signals from the skin to track blood properties.
- Example: Know Labs’ Bio-RFID technology scans glucose without a needle.
🤖 Skin Patches with AI
- AI-integrated micro-needles or ultrasound patches track health metrics painlessly.
- Example: Graphene-based smart patches detect dehydration and BP fluctuations.
📌 Future of AI in Non-Invasive Health Monitoring
- AI-powered smart mirrors and wearables will track health from the skin.
- AI will predict diseases early without blood tests.
- AI-based digital biomarkers will replace invasive lab tests.
