Abstract
This study introduces "Woolitmus" a textile-based wearable pH indicator and sweat analyzer developed using pyranine on wool substrate. Sweat pH analysis is crucial for monitoring health conditions associated with pH imbalances. This capitalizes on pyranine's unique acid dye properties, successfully dyeing on wool fabric to create a comprehensive pH sensor. The sensor exhibits pH responsiveness under both visible and UV light, offering potential as a real-time sweat patch for pH monitoring. The process of dyeing of wool with pyranine is detailed, elucidating the mechanism behind the pH sensitivity backed up by photophysical characterizations. Stability and reversibility tests also confirm the sensor's robustness and performance. The wool fabric-based pH sensor holds promising applications, including health monitoring, disease diagnosis, and lifestyle management. The reported sensor also can simultaneously collect and detect pH levels without support of any addition accessories.

Title
Woolitmus-A Pyranine Embedded Wool Fabric as a Wearable pH Indicator and Sweat Analyzer
Description
In this study, a pH sensor using pyranine dye was developed on wool as a substrate, showing pH responsiveness in visible and UV light. The sensor has potential to serve as a sweat patch for real-time pH monitoring. The pH sensitive patch offers real-time pH monitoring with applications in health and lifestyle management without any supporting accessory, contributing to the growing field of textile-based sensors for healthcare and allied areas.
