Abstract Implantable physiological electrodes provide unprecedented opportunities for real‐time and uninterrupted monitoring of biological signals. Most implantable electronics adopt thin‐film substrates with low permeability that severely hampers tissue metabolism, impeding their long‐term biocompatibility. Recent innovations have seen the advent permeable through strategic modification liquid metals (LMs) onto porous substrates. However, durability these is limited by inherent poor wettability LMs, particularly within intricate 3D skeleton substrate. Herein, study reports a spatial tuning strategy solves issue LMs substrates, enabling LM high The demonstrates use as neural interface to realize in vivo acquisition electrocardiograph electrocorticogram signals biocompatibility signal‐to‐noise ratio. This work promising direction rational design durable bioelectronics

Abstract MXene exhibits an excellent ion‐electron dual conduction mechanism, making it a promising candidate for bio‐interfacing electrodes. However, the exposed Ti atoms on flakes are prone to oxidation in air, leading serious degradation which impedes its application as bioelectronic materials. Herein, new thin film protected by reduced graphene oxide (rGO) (namely rGM), resulting air‐stable electrode with high charge transfer capability is reported. The protective layer rGO effectively shields conductive from air oxidation, thereby significantly enhancing stability. After 40 days (25 °C, 40% RH), sheet resistance of rGM (135.9 ± 2.3 312.6 4.5 Ω sq −1 ) negligible increase compared pure (145.0 2,152.8 6.8 ). A built‐in electric field (BIEF) generated redistribution charges at rGO@MXene heterojunction interface, enhances efficiency and helps reduce interfacial impedance between electrodes biological tissues. Together characteristic, applicable advanced automatic external defibrillator (AED) electrodes, essential advancing emergency treatment research related cardiac arrest.

Abstract Optoelectronic synaptic devices are promising candidate components for brain‐like efficient neuromorphic computing systems. The development of highly‐selective near‐infrared (NIR) optoelectronic is important realizing more optical computing, night monitoring, and robot visual perception. In this work, ultralow‐power (56 aJ per light pulse), NIR (≈850 nm) transistor based on carbon nanotube thin film transistors developed by modification the organic photosensitive material in device channels. showed high sensitivity selectivity to 850 nm pulse light. It noted that response currents after stimulation a single can be nearly six times higher than those stimulated UV light, which attributed IHIC has low bandgap, strong absorption, ideal energy band alignment with nanotubes. Under pulsed stimulation, range complex functions exhibited, including excitatory postsynaptic currents, paired‐pulse facilitation, transition from short‐term plasticity long‐term plasticity, spike‐timing‐dependent image perception memory functions. Significantly, real‐time trajectory tracking car drone under nighttime conditions successfully simulated using array.
