Comparison of Deep Learning Models for Non-Invasive Interstitial Glucose Prediction Using Wearable Sensors in Healthy Cohorts

This pilot study compares deep learning models for predicting blood glucose (interstitial glucose, IG) using only biosignals from wearable devices in healthy individuals. Without requiring food logs or exercise data, the BiLSTM model achieved the best prediction performance (RMSE 13.42 mg/dL) using only wrist-worn sensor data, opening possibilities for convenient non-invasive blood glucose monitoring in daily life.
