However, achieving durability and resistance to disruption while enhancing tactile sensing capabilities remains a critical challenge. In this study, we propose a dual-mode tactile sensing strategy with comprehensive self-healing capabilities, combining piezoresistive and piezoelectric sensing to accurately simulate finger bending and touching motions for perception of dynamic and static stimuli. Especially, we introduce an infusive polydimethylsiloxane (H-PDMS) material with self-healing function as the key component of our tactile sensing system, enabling rapid recovery after damage similar to the self-healing ability of human skin. The size of the object is recognized by the liquid metal-based piezoresistive sensor to mimic changes in finger joint bending, while the contour of the object's surface is recognized by the ceramic nanoparticle-included piezoelectric sensor to simulate the tactile receptors of the finger. During object recognition, signals from both sensors are converted into CMYK color blocks and superimposed, enabling accurate discrimination of object size and surface characteristics. Remarkably, the sensing system achieves a comprehensive recognition rate of 96%, even under damaged conditions, with a self-healing rate in electrical conductivity and sensing capabilities exceeding 90%. This exceptional self-healing performance is driven by the abundant hydrogen bonds of varying strengths within the H-PDMS matrix, which enable the material to recover its original properties following damage. By introducing this self-healing functionality into electronic skin technology, our work paves the way for advanced applications, including robotic object recognition and automated fruit sorting, offering broad prospects for smart systems in various industries.","PeriodicalId":394,"journal":{"name":"Nano Energy","volume":"79 2 1","pages":""},"PeriodicalIF":17.6,"publicationDate":"2025-02-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143258187","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}

Herein, we propose a mechanical-thermal hybrid rotational nanogenerator that not only reutilizes waste heat energy and captures rotational mechanical energy but also enables active detection of rotation speed and temperature. An unpowered hood facilitates the transmission of waste heat energy into rotational mechanical energy.

However, for lateral sliding-mode triboelectric nanogenerator (LS-TENG), the triboelectric effect is accompanied by material wear, and the electric field in the contact gap can be distorted by charged debris, so it remains unclear about the impact of pump voltage on the triboelectrification effect and air breakdown behavior. In this paper, the influence of pump voltage on the triboelectric properties of CS-TENG and LS-TENG under dry friction is studied, and then the effects of lubrication by squalane on the tribological and electrical properties of LS-TENG is explored. The results indicate that the threshold of pump voltage for air breakdown is dependent on the working mode of TENG. Specifically, in CS-TENG, the threshold of pump voltage aligns with Paschen's law, whereas in LS-TENG, it is deviates from this law. For LS-TENG, as the pump voltage increases, the electrical output initially decreases and subsequently increases, which is attributed to the adsorption of the transfer film by the electric field generated by the pump voltage. When the pump voltage increases further until air breakdown occurs between the contact surfaces, the charge density decreases again. At this stage, the transfer film at the friction interface is destroyed by air breakdown, leading to intensified wear, surface degradation, and reduced durability of the LS-TENG. The addition of an appropriate amount of squalane to the contact interface effectively prevented the formation of the transfer film, thereby enhancing durability. Moreover, squalane suppresses the air breakdown by filling the air gap and forming a lubrication film with high dielectric constant, which significantly improved the electrical output of the TENG. This study provides theoretical insights and guidance for the design of LS-TENG under charge pump with improved durability and electrical performance.","PeriodicalId":394,"journal":{"name":"Nano Energy","volume":"11 1","pages":""},"PeriodicalIF":17.6,"publicationDate":"2025-02-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143257841","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}
