| description | Abstract Conductive fiber membranes have received widespread attention due to their excellent physical and chemical properties. However, developing conductive fiber membranes for both strain sensing and energy harvesting remains a challenge. Herein, a novel thermoplastic polyurethane (TPU)/polydopamine (PDA)/MXene/carbon black (CB) (TPMC) conductive fibrous membrane is developed by combining electrospinning and layer‐by‐layer dip‐coating processes. The TPMC fibrous membrane can be used as a component of strain sensors and triboelectric nanogenerators (TENG) to achieve dual‐mode human motion detection and energy harvesting. The strain sensor boasts a wide operating range (0.5%‐195%), excellent sensitivity (with a gauge factor (GF) up to 54 at 50% strain and maximum GF of 6.5×104), fast response (80 ms) and excellent cycle durability (over 10 000 cycles), making it possible to detect slight or heavy human activities under various conditions effectively. Additionally, a single‐electrode TENG utilizing the TPMC membrane achieves an output voltage of 115 V, a current of 0.8 µA, and a power density of 68 mW m⁻2, also serving as a self‐powered sensor for various movements. The excellent dual‐mode sensing and energy harvesting properties make it promising for future high‐performance wearable devices. |
