Nowadays, there is an urgent need for humanoid robots containing human finger-like electronic skins with mechanical endurance and tactile perception. This study reports the development of an ionotronic skin-based humanoid robot hand that can recognize objects precisely through finger tapping or touching. The ionotronic skin is composed of a cytoskeleton-like filament network structure and possesses mechanical properties highly akin to human skins, including softness (Young’s modulus of 51 ± 15 MPa), toughness (1.6 ± 0.7 MJ m–3), and antifatigue-fracture ability. In addition, the i-skin functions as a triboelectric nanogenerator with the ability to perceive the triboelectric signals of an object when in contact with it. By combining triboelectric sensing information, machine learning, and Internet of Things techniques, the humanoid robot hand can accurately recognize different materials among a diverse set of spherical objects and further deliver them to the designated location. The high sorting success rate of 97.2% in 600 tests of recognizing five types of spherical objects, together with the outstanding mechanical and environmental tolerance, allow such humanoid robot hands to be used for intelligent sorting, automatic operation, and assembly in unmanned factories, as well as for the classification of garbage and hazardous materials.

Digital Twins
In article number 2202660, Dongsheng Ren, Jingyi Qiu, Jingliang Wang, Xiangming He, Hao Zhang, and co-workers propose a digital twin-based approach for rational design of ultrahigh-power LiFePO4/graphite lithium-ion batteries. Model-driven optimization of ultrahigh-power LiFePO4/graphite batteries is successfully realized, aiming at the critical factors in the rate-determining steps. The battery shows a high energy density of 92.38 Wh kg−1 at an ultrafast discharging current of 50 C and can withstand 150 C pulse discharging.

Early Stage Exposure of 1H,1H,2H,2H-Perfluorooctanesulfonate-Induced Cardiovascular Abnormality in Zebrafish Embryos and Larvae

Ling Wang, Siyi Chen, Huixin Hou, Mengxi Cao, Zhen Zhou, Huiming Cao, Minjie Chen, Yong Liang, and Yawei Wang

The novel per- and polyfluoroalkyl substances (PFAS) have attracted global attention due to their persistence, bioaccumulation, and various toxicities. Few studies have focused on the toxicological effects of 1H,1H,2H,2H-perfluorooctanesulfonic acid (6:2 FTS), an alternative of perfluorooctanesulfonate (PFOS) detected worldwide. In this study, PFOS was used as a positive control to evaluate the developmental toxicity of 6:2 FTS in zebrafish embryos and larvae. The results of embryo exposure showed that the acute toxicity of 6:2 FTS was lower than that of PFOS. 6:2 FTS could affect the development of zebrafish, including increasing the utilization of yolk sac and the length of the pharyngeal pouch, leading to pericardial edema and inhibiting beating of the heart. Then transgenic zebrafish CZ63 and CZ40 were used to further explore its cardiovascular toxicity. 6:2 FTS could induce vascular hyperplasia, inhibit atrial development, and reduce blood flow velocity in larvae at 72 hours postfertilization. By employing transcriptome analysis and reverse transcription polymerase chain reaction, the involved molecular pathway was finally investigated. Two micromolar 6:2 FTS enhanced the activity of CAT and GSH-Px, involved in calcium signal transduction and myocardial contraction, and affected the MAPK, FoxO, and p53 signaling pathways. Our study can provide scientific insight into the biological safety and health risk of 6:2 FTS.

Flexible Optoelectronics
In article number 2205038, Huae Xu, Hongyi Liu, Jing Ji, Yun Chen, and co-workers present an injectable, reactive oxygen species-responsive therapeutic hydrogel (ADU-AAV-PD1@Gel), capable of sustained local release of soluble PD-1 (sPD-1) and STING agonist ADU-S100. The ADU-AAV-PD1@Gel combined with radiotherapy generates a robust antitumor immune response and induces long-term immune memory to prevent glioblastoma recurrence.
