Sensor de presión flexible de alta sensibilidad lineal basado en material MXeno/Algodón y contacto de interfaz

Flexible pressure sensors have broad application prospects in wearable medical health monitoring, human-computer interaction, and electronic skin fields. However, the preparation of flexible pressure sensors with high linear sensitivity by using simple processes remains a huge challenge. In this work, a new strategy for high linear sensitivity flexible pressure sensors based on MXene/cotton fiber materials was reported. By injection of MXene material as a sensitive layer into the cotton fiber material of medical wound dressings, high linear sensitivity flexible pressure sensors can be easily prepared. The obtained sensor achieves a single linear high sensitivity (39.91 kPa^-1 at 0-10 kPa, with a linear coefficient of up to 0.99972) and has a low detection limit of 5 Pa. This work provides insights into the design and application of a single-linear high-sensitivity flexible pressure sensor based on MXene materials, which holds broad application prospects in flexible wearable medical health monitoring and other fields.
