Wireless-charging in-plane microbatteries (MBs) with conformal shape and high-capacity hold substantial promise in advancing the practical applications of complexly configured electronic devices. However, integrating these MBs seamlessly with flexible electronic system remains a challenge as it requires a rational structure design and reasonable materials engineering for the micropower system, ensuring both high compatibility and robust mechanical stability. Here, we present stretchable and wireless-charging dual-plating MBs that integrate seamlessly into circuits through an omnidirectional stretch-contraction strategy coupled with mask-assisted printing. The strain-induced folding structures and no active-material design endow the wireless-charging MBs with reliable deformation-tolerant capabilities, which can sustain ~200% omnidirectional strains and have advantages of an order of magnitude in terms of power and energy densities, compared to the existing in-plane MBs. With the exceptional compatible and elastic properties, a wirelessly charging stretchable display integrated circuit and even intelligent electronic skin are achieved, capable of mimicking human touch to sense the weight, temperature, and shape of objects.

The wire electrical conduction is a traditional method to transfer carriers from external circuit into internal functional materials in electronic devices, yet these guest carriers suffer ineluctable dissipation on their traveling paths before contributing device performance. Hereof, a wireless electrostatic induction strategy is developed to activate native carriers just inside MXene-based electrochemical supercapacitive device for facilitating carrier utilization. Experimental and simulative results reveal that in the device domains permeated by atmospheric electric field, the native carriers are effectively excited not only in porous MXene material, but also in metallic foil substrate and ionic electrolyte, endowing a huge energy capacity of 541.6 F g − 1 , greatly larger than 258.5 F g − 1 implemented by wire conductive charge. Further, the inducing system is explored to detect the atmospheric electric field strength with the highest sensitivity of 14.42 m μA V − 1 and high linearity of 95.22% in ranging 0–1100 V m − 1 and is also utilized to sense contactless proximity stimulus with a high sensitivity of 7.01 μA m − 1 and high linearity of 97.9% in penetration depth ranging 0∼20 cm. These smart functions are also realized with prototype equipment for applicable exploration.

For electronics to be wearable, contactless charging and overall deformability are necessary pre-conditions. However, the current heterogeneous integration based on different active materials and separate manufacturing often leads to mechanical mismatch. Here, we report an ultrastretchable all-in-one integrated MXene-based microsystem comprising wireless coils, micro-supercapacitors (MSCs) and strain sensors. The seamless configuration without any connecting interface dramatically improves the structural integrity of the microsystem, and a pre-crumpled structure endows it with superior stretchability. Attributed to these, our MSCs can be wirelessly charged in ~20 s under various types of deformation and are capable of powering strain sensors, responding rapidly to body motion signals. Moreover, the MSCs display a high specific capacitance of 76.82 F cm –3 , and superb mechanical stability with 98.5% capacitance retention after biaxial stretching 1000 cycles from 0% to 500% areal strain. Therefore, this work sheds new insights into design and implementation of skin-attachable wireless microelectronics.

With the rapid development of wireless charging technology, there is a growing demand for ferrite materials with high permeability, high saturation magnetic induction intensity, and low power loss. This study aims to enhance the electromagnetic performance of NiCuZn ferrite by co-doping Nb 5+ and Li + . The influence of the doping levels Nb 5+ and Li + on the morphology, crystal structure, and electromagnetic properties of NiCuZn ferrite were studied in detail. Structural analysis shows that the lattice constant decreases as the Nb 5+ -Li + doping concentration increases, and the NiCuZn ferrite exhibits a high density and homogeneous microscopic morphology at the optimum concentration of x = 0.004. Specifically, at a doping concentration of x = 0.004, the magnetic permeability at 1 MHz measured at 1112.1, the saturation magnetic induction intensity reached 458.98 mT, and the power loss was minimized to 521.85 kW/m 3 , demonstrating significant improvement in the transmission power of wireless charging applications.

Fabrication of miniature-integrated devices combining energy harvester, energy storage, and various sensors via simple, fast, and efficient ways is strongly desired for the practical application of integrated smart systems. Herein, this work presents a simple one-step laser scribing method to prepare an all MXene-based seamlessly integrated system with integrated wireless charging coil, micro-supercapacitor, and photodetector in a small area of only 1.78 cm 2 . All the three modules in the integrated system are composed entirely of Ti 3 C 2 T x MXene and are connected with highly conductive MXene wires without additional welding or assembling operation. The energy is first received by the wireless charging coil and then stored in the Zn-ion micro-supercapacitor, which is subsequently used to drive the surface-modified (dodecyl triethoxysilane) DCTES-MXene-based photodetector, thus realizing the complete energy cycles. This work conceptually illustrates a simple method for designing and preparing integrated multifunctional wearable devices.

Portable and wearable devices have attracted wide research attention due to their intimate relations with human daily life. As basic structures in the devices, the preparation of high-conductive metallic circuits or micro-circuits on flexible substrates should be facile, cost-effective, and easily integrated with other electronic units. In this work, high-conductive carbon/Ni composite structures were prepared by using a facile laser direct writing method, followed by an electroless Ni plating process, which exhibit a 3-order lower sheet resistance of less than 0.1 ohm/sq compared to original structures before plating, showing the potential for practical use. The carbon/Ni composite structures exhibited a certain flexibility and excellent anti-scratch property due to the tight deposition of Ni layers on carbon surfaces. On the basis of this approach, a wireless charging and storage device on a polyimide film was demonstrated by integrating an outer rectangle carbon/Ni composite coil for harvesting electromagnetic waves and an inner carbon micro-supercapacitor for energy storage, which can be fast charged wirelessly by a commercial wireless charger. Furthermore, a near-field communication (NFC) tag was prepared by combining a carbon/Ni composite coil for harvesting signals and a commercial IC chip for data storage, which can be used as an NFC tag for practical application.

The rapid advancement of wireless charging systems (WCSs), fifth-generation (5G) technology, electric vehicles (EVs), and artificial intelligence (AI) systems result in a critical need for more efficient thermal management materials. h-BN, characterized by its ultra-high theoretical thermal conductivity and excellent electrically insulating properties, serves as a promising filler for blending with polymers to develop high-performance thermally conductive composites. However, it is still a challenge to attain a high through-plane thermal conductivity of over 40 Wm −1 K −1 at filler content at 80 vol%. This persistent limitation is mainly attributed to the fact that most current h-BN used in the manufacture of thermal conductive composites has relatively smaller lateral size (below 40 µm). Additionally, the effective orientation strategy (e.g., ice-template strategy) usually results in difficulties in mass production. Here, a two-step process involving blade coating and lamination is used to prepare BN/TPU composites with an through-plane thermal conductivity of 43 Wm −1 K −1 at h-BN content of 67 vol%. With upper-level electric insulating properties and wave-transparent characteristic, the multifunctional BN/TPU composite shows excellent thermal management ability in the high-power wireless charging area and also has the potential to be used in the 5G communication technology field.

The limited energy density of micro-supercapacitors (MSCs) and challenges in their integration significantly impede the advancement of MSCs in wearable electronic devices. Here, this work designs a robust and wrinkled liquid metal-CNT-PEDOT:PSS film with high capacity and self-healing properties (defined as LM-CNT-PEDOT:PSS). The wrinkled structure further enhances tensile properties of LM-CNT-PEDOT:PSS and increases its active specific surface area per unit. Simultaneously, the incorporation of liquid metal (LM) enhances both the mechanical and healing properties of the LM-CNT-PEDOT:PSS electrode. The flexible and self-healing MSC based on wrinkled LM-CNT-PEDOT:PSS shows a remarkable specific capacitance of 114.29 mF cm −2 and a high areal energy density of 15.47 µW h cm −2 . Furthermore, the electrochemical performance of the healed MSC retained 90.01% of its initial performance, and the MSC unit can be arbitrarily integrated according to various energy and voltage requirements through the healing properties of LM-CNT-PEDOT:PSS, widening the range of applications in next-generation microelectronic devices. The wrinkled LM-CNT-PEDOT:PSS film is utilized for the fabrication of a highly sensitive strain sensor. Simultaneously, the prepared sensor can be seamlessly integrated with wireless charging and MSC to facilitate convenient monitoring of physiological signals, thereby offering an effective solution for the advancement of wearable technology and self-powered systems.
