Abstract Anisotropy control of the electronic structure in inorganic semiconductors is an important step developing devices endowed with multi-function. Here, we demonstrate that intrinsic anisotropy tellurium nanowires can be used to modulate and piezoelectric polarization decouple pressure temperature difference signals, realize VR interaction neuro-reflex applications. The architecture design device combined self-locking effect eliminate dependence on displacement, enabling a single determine hardness thermal conductivity materials through simple touch. We bimodal Te-based sensor develop wearable glove for endowing real objects virtual world, which greatly improves somatosensory feedback. In addition, successfully achieved stimulus recognition neural-reflex rabbit sciatic nerve model by integrating signals using deep learning technique. view in-/ex-vivo feasibility, would considered novel sensing platform wide range application metaverse, AI robot, medicine.

Electronic skin (e-skin), a new generation of flexible electronics, has drawn interest in soft robotics, artificial intelligence, and biomedical devices. However, most existing e-skins involve complex preparation procedures are characterized by single-sensing capability insufficient scalability. Here, we report on one-step strategy which thermionic source is used for the situ molecularization bacterial cellulose polymeric fibers into molecular chains, controllably constructing an ionogel with scalable mode e-skin. The synergistic effect molecular-scale hydrogen bond interweaving network nanoscale fiber skeleton confers robust tensile strength (up to 7.8 MPa) high ionic conductivity 62.58 mS/cm) as-developed ionogel. Inspired tongue engineer perceptual patterns this ionogel, present smart e-skin perfect combination excellent ion transport discriminability, showing six stimulating responses pressure, touch, temperature, humidity, magnetic force, even astringency. This study proposes simple, efficient, controllable, sustainable approach toward low-carbon, versatile, design structure-performance development.

Tactile sensations are mainly transmitted to each other by physical touch. Wireless touch perception could be a revolution for us interact with the world. Here, we report wireless self-sensing and haptic-reproducing electronic skin (e-skin) realize noncontact communications. A flexible actuator was developed provide an integrated function in both tactile sensing haptic feedback. When this e-skin dynamically pressed, generated induced voltage as information. Via communication, another receive data run synchronized reproduction. Thus, wirelessly conveyed bidirections between two users intercom. Furthermore, connected various smart devices form internet of things where one-to-one one-to-multiple delivery realized. This presents huge potentials remote video, medical care/assistance, education, many applications.

Thermal management plays a notable role in electronics, especially for the emerging wearable and skin as level of integration, multifunction, miniaturization such electronics is determined by thermal management. Here, we report generic strategy using an ultrathin, soft, radiative-cooling interface (USRI), which allows cooling down temperature through both radiative nonradiative heat transfer, achieving reduction greater than 56°C. The light intrinsically flexible nature USRI enables its use conformable sealing layer hence can be readily integrated with electronics. Demonstrations include passive Joule circuits, improving working efficiency epidermal stabling performance outputs skin-interfaced wireless photoplethysmography sensors. These results offer alternative pathway toward effective advanced multifunctionally wirelessly operated health care monitoring.

Architected flexible electronic devices with rationally designed 3D geometries have found essential applications in biology, medicine, therapeutics, sensing/imaging, energy, robotics, and daily healthcare. Mechanically-guided assembly methods, exploiting mechanics principles of materials structures to transform planar fabricated using mature semiconductor techniques into architected ones, are promising routes such devices. Here, we comprehensively review mechanically-guided methods for electronics. Mainstream classified discussed on the basis their fundamental deformation modes (i.e., rolling, folding, curving, buckling). Diverse interconnects device forms then summarized, which correspond two key components an device.
