The electrical energy is generated by the combined effect of contact electrification occurring at triboelectric surfaces and the transfer of charges through the electrodes of s-TENGs which can be used for a range of applications such as self-powered sensors in Internet of Things (IoTs), sensing ambient conditions, bio medical treatments, and rehabilitation. The s-TENGs are effective in harvesting low-frequency mechanical movements (2–5 Hz), due to the low elastic modulus of their stretchable triboelectric surfaces and electrodes. Herein, a comprehensive system-level performance of both stretchable triboelectric surfaces and stretchable electrodes towards their successful deployment in s-TENGs have been reviewed. We specifically review the challenges associated with triboelectric surfaces of s-TENGs such as low charge density, environmental toxicity, limited contact area and limited lifespan. Besides, the low conductivity and the issues associated with drying, freezing and mechanical integrity of the hydrogel electrodes (HEs) as well as the challenges of agglomeration, oxidation, high surface tension of liquid metal (LM) electrodes are critically evaluated based on the published literature during the last twelve years (2013 – 2025). Significant research gaps have been identified despite substantial research towards performance enhancement for the realization of practical TENGs. Initiatives required to practically deploy s-TENGs and a roadmap towards this goal also have been discussed.</div></div>","PeriodicalId":394,"journal":{"name":"Nano Energy","volume":"142 ","pages":"Article 111244"},"PeriodicalIF":16.8,"publicationDate":"2025-06-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144296225","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Currently available synaptic devices often adopt electrical parameters as their synaptic weight, whereas electrochromic artificial synapses with optical synaptic weight, providing unique visual functionality, are highly desirable yet challenging. We report a universal strategy to construct flexible multicolored hydrogel devices with different viologen derivatives. Using transmittance as their optical postsynaptic potential, these viologen-based artificial synapses demonstrate synaptic plasticity in coloration, dependent on the amplitude, duration, number, and frequency of electrical stimulating pulses. The synaptic features of the electrochromic devices, such as paired-pulse facilitation and short-term memory, can be regulated readily by selecting different viologen molecules. Typically, in response to a low-voltage stimulus of 2.0 V at 1.0 Hz, the transmittance of the viologen-based device is significantly reduced by 84 % after 100 pulses, with a short-term retention exceeding 300 s. By leveraging a simple combination of two different wearable electrochromic synapses with distinct levels of synaptic plasticity, electrocardiogram signals are able to be converted into intuitive color changes, offering real-time visualized health feedback.

In this work, we utilize theoretical calculations to disentangle the chemical components in the solid electrolyte interphase (SEI) and dendrites, systematically analyzing the physicochemical properties of each component.

Conversely, D-LiH, with its electronic insulation and extreme brittleness, is identified as the primary cause of capacity decay and anode pulverization. Furthermore, by analyzing electrochemical windows, we explore the thermodynamic mechanisms underpinning the formation, transformation, and decomposition of SEI and dendrite components, providing theoretical explanations for experimental anomalies associated with LiH.
