Abstract The greener alternatives to tactile‐integrated multimodal sensors with self‐powered and self‐healing abilities are highly desirable for all‐in‐one autonomous sensing systems, particularly impressive in diverse application ranges including smart home, healthcare, e‐skin. dynamically self‐healable, stretchable piezoresistive sensors, triboelectric nanogenerators (TENGs) reported herein constructed by a facile, industrially viable method of grafting imidazolium ions on epoxidized natural rubber (ENR) backbone. Owing cation‐ π π–π interaction between the percolated carbon nanotubes (CNTs)‐network formed non‐covalent interactions, interfacial adhesion filler elastomer is shown improve considerably. show high strain sensitivity, reversible ionic network‐assisted self‐healability (efficiency ≈80%) wide‐ranging detectability precise monitoring human movements. Both healed pristine feature low hysteresis stable electrical outputs over wide range (≤200%). While achieving rapid efficiency, substrates exhibit remarkable robustness harsh climates owing significant mechanical toughness. Supported excellent tactile sensitivity (2.12 V N −1 ), multifunctional TENG‐enabled sensor yields superior power density (0.16 mW cm −2 ). Moreover, TENG module exhibits force ease operation that considered versatile all‐weather integrated solutions future technology.

Stretchable, flexible sensors are one of the most critical components smart wearable electronics and Internet Things (IoT), thereby attracting multipronged research interest in last decades. Following miniaturization multicomponent development several could further propel demand for wireless, multimodal platforms. Greener substitutes to conventional that can operate a self-powered configuration highly desirable terms all-in-one sensor utilities. However, fabrication composite-based ultrastretchable, with multifunctionality, robustness, conformability is still only partially achieved and, therefore, demands investigation. In this work, we report triboelectric nanogenerator (TENG)-based multifunctional strain organic vapor using cross-linked ethylene propylene diene monomer (EPDM) elastomer conducting carbon black as active fillers presence an ionic liquid. The resulting piezoresistive demonstrates ultrahigh gauge factor (GF > 220k) wide range sensitivity is, suitable subtle-to-high frequency motion detection devices.

Self-healing materials have garnered significant attention for their potential to heal damage when it occurs. Elastomers, particularly natural rubber, been a focal point of extensive research in the realm self-healing materials. The ability rubber not only promises extend service life rubber-based products but also offers new avenues recyclability and reprocessability, contributing environmental protection efforts. A key challenge has enhance its capabilities without compromising mechanical properties. As result, various mechanisms such as hydrogen bond, Diels–Alder (D-A) reaction, disulfide imine ionic bond thoroughly investigated. Among these mechanisms, reversible bonds or interactions emerged influential facilitating rubber. This mechanism is easily incorporated into structure due high stability, enabling exhibit promising review delves comprehensive statistical analysis numerous published articles focuses on exploration bonding context Additionally, provides succinct introduction specialized tests designed assess focusing related methods evaluation, namely swelling test healing efficiency test.

Abstract Bio‐based resources as reinforcing agents for elastomers is an important area of research. In this study, different types lignin were employed fillers synthetic elastomers. Polychloroprene (CR), a polar rubber, and solution styrene butadiene rubber (SSBR), non‐polar used matrix materials. Results showed that filled with Kraft exhibited better mechanical performance than those lignosulfonate. Without chemical modification, effectively reinforced polychloroprene increasing its tensile strength by 3.5 times, modulus 2 elongation at the break times. However, SSBR, use surface modifiers such alkyl isocyanates improved dispersion efficiency lignin. Particularly, in SSBR system values crossed 900%, which very high like SSBR. A noticeable improvement was observed field emission scanning electron microscopy when situ modification done isocyanates. To understand effect lignin, various mechanical, dynamic physical tests conducted composites.

Dielectric Elastomer Generator (DEG) stands out as a promising electromechanical device to harness energy from non-conventional sources owing its ability convert mechanical into electrical power. DEG with no rotating part demonstrates high performance-to-weight ratio ease in fabrication and compactness that sets it apart traditional harvesting techniques. Triboelectric nanogenerators (TENGs) belong self-powered class of capitalizes on low-frequency amplitude sources. Existing models for predicting the performance TENGs often assume parameters such frequency, amplitude, relative permittivity are constant. However, these can vary depending specific application. In this study, modified model is proposed comprehensively investigate TENG real-world conditions considering fluctuations varying elastomer layers. Results indicate at higher frequency 55 Hz, there significant increase output voltage, attributed release rate due increased velocity. The study also emphasizes role layers, revealing layers dielectric constants generate more voltage power (151\%) compared those lower values, particularly separation distance 0.1mm. findings exhibit notable concurrence previously reported values offer valuable framework researchers seeking tailor generators enhanced precision harnessing low-amplitude

Abstract Natural rubber (NR) consists of mainly cis ‐1,4‐polyisoprene with proteins as notable nonrubber components that significantly influence its properties. A relatively unexplored aspect is the role these in reducing and stabilizing metal ions to form metallic particles. Here, NR/ZnO composite successfully prepared by situ generation ZnO NR latex for first time. With aid proteins, amount slightly higher than formed saponified (SPNR), where some are removed. Importantly, noncovalent bonds between and/or amino acids can provide self‐healing behavior composite. However, heating at ≈40 °C still necessary healing time increasing efficiency Nevertheless, greater within hinder molecular chain interdiffusion rearrangement essential uncross‐linked rubber, resulting lower compared SPNR/ZnO. This study underscores significance on NR's properties, despite their minor presence. Without sophisticated modification, this a very simple low‐cost technique achieve behavior.
