Optoelectronic Properties of PEDOT and Their Application in Flexible Wearable Blood Oxygen Monitors

In recent years, with the rapid advancement of technology and increasing attention to health management, wearable medical devices such as smart bracelets and health monitoring watches have gradually become part of daily life. Among these devices, blood oxygen monitoring equipment has garnered significant attention due to its ability to reflect the saturation level of oxygen in human blood in real time, which is crucial for early detection of respiratory diseases and assessment of overall health. This paper focuses on the promising organic semiconductor material PEDOT, using qualitative methods to delve into its optoelectronic properties and current application status. The study found that PEDOT exhibits excellent optoelectronic characteristics. Based on the PPG principle, it should be effectively applicable to blood oxygen sensor modules, enhancing the accuracy and flexibility of blood oxygen detection. Furthermore, PEDOT has found extensive application in diverse domains, such as medical health devices, including blood oxygen meters, and various flexible electronic devices. It is anticipated to remain a pivotal material in the ongoing development of blood oxygen meters and associated flexible electronic devices.
