The sensor, designed to be worn directly on the skin, is suitable for real-time monitoring of the recovery level of not only general wounds, but also difficult-to-heal wounds, such as those with chronic inflammation. Notably, healthy skin has a pH range of 4-6. When a wound occurs, the pH is known to be approximately 7.

- Hydroxypropyl cellulose (HPC) is a biodegradable heat-responsive polymer commonly used in safe consumer products like food and medicine, which changes behavior with temperature due to hydrophilic and hydrophobic bonds.
- This study explored a display system using HPC's thermoreversible phase transition by applying localized near-infrared (NIR) lasers to control temperature, enhanced by cesium tungsten oxide (CTO) for heat generation and carbon nanotubes (CNTs) for efficient heat transfer.
- The resulting NIR-writing CTO-CNT-HPC display demonstrated rapid responsiveness, making it suitable for applications like interactive advertising, navigation, and public announcements.
Color-changing fibers, which can intuitively convey information to the human eye, can be used to facilely add functionality to various types of clothing. However, they are often expensive and complex, and can suffer from low durability. Therefore, in this study, we developed highly elastic and hydrophobic thermochromic fibers as wearable temperature sensors using a simple method that does not require an electric current.
