Textile-Based Blue Organic Light-Emitting Diode and Organic Photodiode for Wearable Sensor-Integrated Display

In recent years, the demand for non-invasive wearable medical devices has surged, driven by the need for continuous health monitoring. This study presents a novel platform that utilizes a textile-based organic light-emitting diode (OLED) and organic photodiode (OPD) to monitor body vitals in real time. By employing a single blue light source, the platform effectively measures photoplethysmography (PPG) signals, demonstrating its potential for practical applications in health management. The textile-based OLED shows a peak wavelength of 470 nm and maintains performance comparable to previous glass-based devices. Additionally, the OPD shows promising capabilities for detecting PPG signals, indicating its effectiveness in capturing vital signs. This innovative approach paves the way for advanced wearable technologies that enhance people care and facilitate health monitoring anytime anywhere.
