VeinFinder is a portable vein locator that pairs force-sensitive pressure mapping with AI-driven prediction: 93.3% detection accuracy, built for under $100.
Tested across 30 independent trials simulating subcutaneous vein tissue, with additional validation on human skin. Each trial recorded a vein / non-vein classification and response time.
Vein tissue produces a consistently distinguishable signal versus surrounding tissue, clear enough to classify in real time, without imaging or specialized training to operate.
VeinFinder is evolving beyond single-point sensing into a full predictive mapping system, using machine learning to turn raw pressure signal into a real-time spatial map of vein location, depth, and optimal access point.
Machine learning fills the gaps between sensor readings, building a continuous map from discrete pressure data.
The model learns to recommend the optimal access point, not just where a vein is, but where to insert.
Every trial sharpens the model further, with accuracy compounding as the dataset grows toward clinical deployment.
