Lack of a convenient and sustainable power supply device failure after material damage are important factors limiting the development traditional wearable sensors. In this study, self-healing triboelectric nanogenerator (TENG) was designed prepared for motion sensing energy harvesting. Hydrogen bonds disulfide were introduced into polyurethane (PU) chain segment to provide it with ability. Then, carbon nanotubes (CNTs) added PU confer electrical conductivity composite film. The conductive film is sandwiched between original films as an electrode in sandwich structure, three-layer tightly bonded by hydrogen using simple hot-pressing method. output performance TENG contact area 4 cm2 can reach 89.4 V 96 μW/cm2 because effect. still retain 95.6% its being broken then healed. regard, be applied harvesting human monitoring motion, which shows huge application potential devices.

Stretchable strain sensors integrated with supercapacitor functions have drawn significant attention due to their wide potential applications. In this study, a composite fiber core-shell structure is fabricated via coaxial wet spinning method enhance the comprehensive properties. The uses thermoplastic polyurethane (TPU) and polypyrrole (PPy) as shell layer poly(3,4-ethylenedioxythiophene) (PEDOT) single-walled carbon nanotubes (SWCNTs) core layer. By optimizing contents of PPy, SWCNTs, TPU, we obtain stretchable both sensing electrochemical results show that when content PPy 1.5%, SWCNTs 0.7%, TPU 10%, prepared fibers exhibit excellent mechanical properties, stress 65.7 MPa, 374.8%, mass-specific capacitance 759.5 F/g. can accurately recognize human body movements in finger bending cycle tests high gauge factor (76.5, for stretch range 40-50%) stable cyclic tensile response (4000 cycles), which indicates good
