Thermoelectric generators (TEGs) are a promising technology, which convert waste or body heat into electricity. However, their power output is severely limited by the thermal impedance mismatch, particularly between the human skin and TEG interface. This work introduces a novel approach to overcome this limitation by integrating a hydrogel into the TEG system. It has been revealed that the enthalpy from the hydrogel's water evaporation effectively achieves thermal impedance matching while simultaneously maximizing the heat flux. Furthermore, by optimizing the TEG's fill-factor, we increased the power density by nearly two orders of magnitude compared to conventional TEG systems. As a proof of concept, our device combined body heat with hydrogel evaporation using an optimized fill-factor of 0.48 (using 52 % less material). This setup achieved a power density of 150 μWcm⁻², which was sufficient to power four wireless sensors. This work demonstrates a counter-intuitive synergistic benefit, that is achieving superior thermal matching while significantly reducing thermoelectric material usage.

By leveraging graphdiyne (GDY)’s electron-rich sp-carbon bonding network and intrinsic triangular cavities as a host matrix, we covalently embed Fe₂(CO)₉ guest molecules into its voids, enabling precise nesting of Fe₂ pairs at cavity centers.

The difficulty originates from uncontrolled oxygen distribution and nonuniform crosslinking during preoxidation, which lead to undesired coking and limited pore confinement after carbonization. Herein, we introduce a sequential air-acid-air (AAA) pulsed strategy that programs oxygen flux to achieve homogeneous crosslinking in low-softening-point petroleum pitch before carbonization. Short liquid-oxidation pulses with intermediate drying suppress surface densification and guide the controlled uptake and staged removal of oxygenated groups. The resulting microstructure features confined voids and interlocking edge defects with tuned interlayer spacing, enabling fast Na⁺ transport and plateau storage. Combining high capacity and durability, the optimized AAA-PHC-1400 achieves a Na⁺ storage capacity of 392.9 mAh g⁻¹ with an 87.4 % initial Coulombic efficiency (ICE) and retains 89.0 % of its original capacity after 2900 cycles, while Na₃V₂(PO₄)₂F₃ (NVPF)|AAA-PHC-1400 full cells maintain 86.6 % of its original capacity after 100 cycles. By varying the liquid oxidant chemistry and concentration, terminal pre-oxidation temperature and carbonization temperature, we mapped out a practical process window of linking sequence parameters with pore architecture and electrochemical metrics. Mechanistic evidence from <em>in-situ</em> Raman tracking of band shifts during sodiation, together with EPR and XPS signatures of paramagnetic species at low potentials, corroborates a plateau storage pathway arising from confined pores and tuned interlayer spacing.

Hydrogen bonding between these groups and PVDF molecular chains promotes β-phase crystallization and enables local polarization anchoring. Furthermore, the shear field at the nozzle tip of 3D printer can be utilized for orienting the nanorod-induced self-polarization.

However, the intrinsic transparent photoactive layer typically incurs exciton utilization penalty which requires the CuSCN in replacement of PEDOT:PSS to form an additional exciton splitting interface. Herein, we study the CuSCN-based OSC in the <span>D</span>-poor region for potential over 60 % AVT. Though CuSCN produces higher short-circuit current density (<em>J</em>_<em>SC</em>) than PEDOT:PSS as hole-transporting layer (HTL), the lower fill factor (FF) and its light-healing behavior suppress the power conversion efficiency (PCE) value. Detailed recombination analysis and Cu valence state comparison confirm the hole-trap at CuSCN/photoactive interface as the determinant reason for FF loss and its light-healing behavior. Targeted p-type doping close to the interface increases the FF in CuSCN-based PM6:L8-BO (0.10:1) OSC from 56.0 % to 62.1 % and mitigates the light-healing phenomenon as well as stability problem by hole-trap passivation.

Despite this, the limitations of traditional electroacupuncture treatments are that they do not re-create localized, biologically scaled electrical gradients required to heal wounds, are dependent on external sources of power, and lacks spatial precision. In this case we present an acupuncture platform based on triboelectric, powered by itself that provides spatially localized, low amplitude alternating current (pA-µA scale) directly to wound edges, replicating natural patterns of EF. These triboelectric nanogenerators, embedded in acupuncture needles, neither need external power nor produce alternating currents in a constant frequency when activated by a human. Output in vivo ranged between 0.5 and 12 µA in the acute model and 0.05‐0.8 µA in the chronic model which is consistent with galvanotactic thresholds reported in the literature. We present evidence that TENG-based electrostimulation is more effective than its counterpart in the induction of wound healing, vascular regeneration and immune response. Mechanistically, TENG stimulation decreased proinflammatory cytokines, augmented the anti-inflammatory markers, and augmented the angiogenic markers, and reduced the oxidative stress as well as augmented the eNOS expression. The polarization of the macrophage shift to increased neovascularization and gene expression profiling was confirmed by confocal immunohistochemistry and excellent correlations between current amplitude and biological repair measures. Our results prove triboelectric acupuncture to be a minimally invasive, tunable, and self-powered bioelectronic therapy.
