have been developed mainly based on TiO 2 nanoparticles with the effi ciency of more than 7% and have good stability under deformation. [ 11,12 ] Considering that solar energy is dependent on the weather and people stay most of a day indoors, mechanical energy could be an appropriate complement due to its universal availability. The triboelectric nanogenerator (TENG), [ 13,14 ] coupling the effect of contact-electrifi cation and electrostatic induction, has been demonstrated to be versatile in scavenging different types of mechanical energies, ranging from vibration, [ 15 ] wind, [ 16 ] water wave, [ 17 ] to human motions. [18][19][20] The abundant choice of materials and structure designs of the TENG enable its feasibility in integration with the E-textile for harvesting energy from human motions. Silver coating, [ 21 ] carbon nanotubes, [ 22 ] and carbon fi ber [ 23 ] were applied to textile fi bers, functioning as the electrode of the textile-based or fi ber-based TENG. In our previous studies, a woven TENG textile was realized by electroless deposition (ELD) of conformal and low-cost nickel coating to convert textile yarns/fabrics into conductive electrodes. [ 24 ] Despite these preliminary fi ndings, further research is still required to improve the output power of the TENG textile. Meanwhile, integration of the whole textile-based TENG and solar cell has seldom been found in literature, though several previous works have been reported integrated devices on fl at substrates. [ 25 ] Herein, we developed a grating-structured TENG fabric and its integration with FDSSCs so as to achieve a whole textile-based energy harvesting system. A route of laser-scribing masking and ELD Ni plating was fi rst proposed for the synthesis of conductive circuits/patterns on the textile. Interdigitated grating-structured TENG fabrics were then fabricated in aim to convert low-frequency human motion energy into high-frequency current outputs. By reducing the grating size, large improvements were achieved in the current amplitude and output power. Furthermore, FDSSCs and TENG fabrics were integrated together into a cloth as complementary power devices for harvesting both the energy of sunshine and human motions.The energy-generating device for wearable electronics or E-textiles should be versatile for fashionable and comfortable designs. Whereas, most of the previous reported TENGs for biomechanical energy-harvesting lack this versatility. The ideal TENG for E-textiles is in the form of fabrics. As schemed in Figure 1 a, a power-textile can be designed with the fabrics of the sleeve and underneath the arm (herein after noted as slider fabric and stator fabric, respectively) functioning as two pairs Electronic-textile (E-textile) or smart textile, which integrates multifunctional electronic/optoelectronic devices into fashionable/stylish clothing, holds great promise for the next growth of the market of wearable electronics. [ 1 ] Various components of electronic devices have been demonstrated in smart garments or fabrics, incl...

The demand of flexible energy storage devices for portable and wearable electronics has become increasingly urgent due to the rapid development of microelectronic products, wearable devices, and smart skin. [1][2][3][4][5][6] Some of the most effective and practical technologies for electrochemical energy conversion and storage are batteries, fuel cells, and supercapacitors. [7][8][9][10][11][12][13][14][15] Among them, supercapacitors (SCs) have attracted intensive attentions due to their high power density and long lifecycle. [9,13,[16][17][18] The energy storage is performed by ion adsorption or fast surface redox reaction at the interface between electrodes and electrolyte. Moreover, all-solid-state microsupercapacitors (MSCs) can greatly facilitate the development The graphene with 3D porous network structure is directly laser-induced on polyimide sheets at room temperature in ambient environment by an inexpensive and one-step method, then transferred to silicon rubber substrate to obtain highly stretchable, transparent, and flexible electrode of the all-solidstate planar microsupercapacitors. The electrochemical capacitance properties of the graphene electrodes are further enhanced by nitrogen doping and with conductive poly(3,4-ethylenedioxythiophene) coating. With excellent flexibility, stretchability, and capacitance properties, the planar microsupercapacitors present a great potential in fashionable and comfortable designs for wearable electronics.
