“…By introducing advanced algorithms (machine learning and deep learning, etc.) [ 79 ] and adopting a distributed information processing model, [ 80 ] the information processing efficacy in large‐area sensor array will be greatly improved. In a word, proceeding with the optimization of material/device structures and updating of software/hardware systems, we anticipate that the suspended bilayer sensory system based on the 3D deformation and mechanical contact mechanism shows great promise for applications in bionic electronics and smart human–robot interactions.…”

Artificial sensory systems with synergistic touch and pain perception hold substantial promise for environment interaction and human‐robot communication. However, the realization of biological skin‐like functional integration of sensors with sensitive touch and pain perception still remains a challenge. Here, we propose a concept of suspended electronic skins enabling three‐dimensional deformation‐mechanical contact interactions for achieving synergetic ultra‐sensitive touch and adjustable pain perception. The suspended sensory system can sensitively capture tiny touch stimuli as low as 0.02 Pa and actively perceive pain response with reliable 5200 cycles via 3D deformation and mechanical contact mechanism, respectively. Based on the touch‐pain effect, a visualized feedback demo with miniaturized sensor arrays on artificial fingers is rationally designed to give a pain perception mapping on sharp surfaces. Furthermore, we show the capability of the suspended electronic skin serving as a safe human‐robot communication interface from active and passive view through a feedback control system, demonstrating potential in bionic electronics and intelligent robotics.This article is protected by copyright.

“…These issues lead to electrolyte leakage and the low Coulomb efficiency, which affects the cycle life of the battery and may even lead to a direct short circuit. − Some efforts have been made to address these issues, including modification of the zinc anode surface, electrolyte modification, and multifunctional diaphragm design . Among them, the effort to protect of the zinc anode surface with a solid electrolyte interphase (SEI) is to achieve the goal of inhibiting dendrite growth by adjusting the diffusion behavior of interfacial zinc ions, homogenized charge distribution on the zinc anode surface, and suppressing interfacial side reactions. − …”

In Situ Polymerization of Ionic Liquid with Tunable Phase Separation for Highly Reversible and Ultralong Cycle Life Zn-Ion Battery

Severe Zn dendrite growth and side reactions greatly limit the application of aqueous zinc-ion batteries. Herein, we design a layer of polyionic liquid (PCAVImBr) film with a tunable pore size and charge density on the Zn anode to endow homogenized distribution of an electronic field, acerated Zn2+ permeation, and inhabitation of water entry. Such an optimal combination is achieved via a polymerization induced phase separation strategy, where the enhanced cross-linking density arrests the phase separation in a shallow depth and vice versa. Furthermore, the Zn@PCAVImBr electrode has good plating/stripping reversibility, which retains a 99.6% CE efficiency after 3000 cycles. The symmetric cells can achieve a cycle life of more than 2400 h at different current densities. It is worth mentioning that the NVO//Zn@PCAVImBr full cell can still reach a 91.2% capacity retention after nearly 4000 cycles at a high current of 10 A g–1, and provides new insights for the future research of zinc-ion battery anodes.
