Dual-Action Hydrogel Offers New Hope for Rheumatoid Arthritis Treatment

A KAIST research team has developed a dual-functional hydrogel for rheumatoid arthritis that combines joint lubrication with immune regulation. The hydrogel is injectable, functions as a bio-lubricant, and alleviates immune cell–driven joint inflammation, thereby targeting key pathological features of rheumatoid arthritis.

Method that reduces real-world AI training costs and its application to control infectious diseases

To address prevalent data quality issues in real-world AI training, this research focuses on three major challenges. First, it automatically detects and corrects label errors during training, reducing the need for manual data preprocessing. The related paper has had a significant academic impact, being cited over 1,200 times in the past two years. Second, it automatically infers missing labels in time-series data, significantly lowering the cost of manual label acquisition. Third, it removes redundant data and selects a core set of informative samples, achieving comparable model performance while reducing the training time by up to 90%. These technologies have been successfully applied to real-world social problems such as infectious disease prediction and economic impact forecasting. They have been granted patents in both South Korea and the United States.

Wearable hyperspectral photoplethysmography for the continuous monitoring of exercise-induced hypertension

A wearable hyperspectral PPG module using a compact and high-resolution microspectrometer allows continuous, cuff-free blood pressure monitoring with high accuracy by capturing spectral PPG signals and physiological changes during exercise.

Wearable hyperspectral photoplethysmography (HS-PPG) module for blood pressure monitoring. The HS-PPG module integrates a high-resolution microspectrometer and allows the acquisition of the hyperspectral range of PPG signals. Blood pressure levels estimated using the HS-PPG exhibit high accuracy, with R2 values up to 0.95.
