| Outline of Final Research Achievements |
This study aims to develop a new type of wearable and flexible device to allow continuous and real-time vital signals from skin surface by realizing high performance and high reliable physical and chemical sensors. For a chemical sensor, a charge-coupled device concept was applied to a flexible pH sensor, resulting in that high performance sweat pH detection was realized. In addition to the chemical sensors, electrocardiogram, respiration, and skin temperature sensors were developed as physical sensors with high reliability for a long-time monitoring. After characterizing the sensor performances and optimizing the materials and structures, process development was conducted to integrate all sensors on a flexible film. The multimodal flexible sensor sheet and the wireless circuit system was combined to study the physiological monitoring. By attaching the sensor system, real-time and continuous vital monitoring was successfully realized with stable and reliable data collections.
