AB  - With the extensive applications of portable, wearable, and stretchable 
      electronics, the fiber triboelectric nanogenerator (TENG) has been developed 
      particularly and rapidly. However, variable stiffness or even switchable 
      stiffness for the fiber TENG is also urgently needed in some specific service 
      conditions. Here, the functional, reconfigurable fiber TENG is presented for 
      harvesting mechanical energy and self-powered sensors. It is mainly composed of 
      soft tubes with filled low-melting-point alloy (LMPA), conductive wire, and 
      electrically heated wire. Under an input frequency of 3 Hz, this fiber TENG 
      produces a maximum peak power density of 348.5 muW/m. Due to its excellent 
      reconfigurable characteristics, it can be switched back and forth in many 
      different application situations. It can be intelligently used not only as a 
      self-powered tactile and mechanical sensor but also as a self-powered splint for 
      postdisaster relief work. Besides, the cracking detection of a gear and a lead 
      screw is also realized using this fiber TENG. This work strongly promotes the 
      application of variable stiffness LMPAs in the TENG, especially for the 
      reconfigurable fiber TENG. It also promotes the potential self-powered 
      applications of the TENG in the fields of sensors and detection, such as 
      mechanical flaw detection and self-powered tactile detection.
