Haptic perception poses a critical challenge for machine intelligence, as current electronic skins (e-skins) fail to simultaneously achieve high sensitivity, tunable force-sensing properties, and environmental adaptability. Inspired by the human tactile neural network, a flexible e-skin solution based on a biomimetic adaptive mechanism is proposed. By emulating the gating behavior of PZ protein ion channels in Merkel cells, we developed a carbon-based microstructured magneto-responsive force-sensing material (GR-MP-MRE). Leveraging the magnetically induced chaining of NdFeB microparticles and the conductive tunneling gap of multi-walled carbon nanotubes (MWCNTs), a dynamically reconfigurable “island-bridge” network was constructed. This network forms neural synapse-like topological pathways under electromagnetic coupling, enabling dynamic tuning of sensor sensitivity, resolution, and signal-to-noise ratio (SNR) with magnetic fields. When integrated into a robotic dog's paw, the skin intelligently recognizes complex terrain features and distinguishes microscopic differences, offering a novel approach for biomimetic adaptive design in flexible electronics.

Enhancement of supercapacitors (SCs) with high-energy density and high-power density is still a great challenge. In this paper, a facile strategy for in situ anchoring of Co3O4 particles on N doped carbon cloth (pCoNCC) is reported. Due to the interaction of the doped N and Co3O4, the electrochemical performance improves significantly, reaching 1,940.13 mF·cm-2 at 1 mA·cm-2 and energy density of 172.46 µWh·cm-2 at the power density of 400 µW·cm-2, much larger than that without N doping electrode of 28.5 mF·cm-2. An aqueous symmetric supercapacitor (ASSC) assembled by two pCoNCC electrodes achieves a maximum energy density of 447.42 µWh·cm-2 and a highest power density of 8,000 µW·cm-2. Utilizing such a high-energy storage ASSC, a digital watch and a temperature-humidity detector are powered for nearly 1 and 2 h, respectively. Moreover, the ASSC displays a superb electrochemical stability of 87.7% retention after 10,000 cycles at 40 mA·cm-2. This work would provide a new sight to enhance active materials performance and be beneficial for the future energy storage and supply systems.
