A reutilization strategy for disposed plants is proposed for the fabrication of pressure sensor, which is achieved by the assembly of oil-flax nonwoven fabric, MXene, polydimethylsiloxane (PDMS) and interdigital electrode. The sensor exhibits excellent sensing performance, including a high sensitivity of 6.25 kPa−1, a wide sensing range of 100 kPa, and exceptional stability over 700 loading cycles. These characteristics make the sensor suitable for various applications, such as human movement monitoring, air flow monitoring, speech recognition, and touch screens. This method of utilizing discarded plants to develop smart wearable devices holds great significance in terms of effective resource utilization and the expansion of application domains.
