The electricity generation of triboelectric nanogenerators (TENGs) originates from charge transfer enabled by contact electrification. However, the inherent barrier between two contacting surfaces hampers transfer. There are mainly four ways to promote triboelectrification TENGs. While synergy among them has never been achieved. Herein, we reported an effective strategy boost efficiency synergizing strong ferroelectric polarization and high permittivity embedded lead zirconate titanate fillers. influence interfacial intensity dielectric permittivity, as well corona poling, on composite film was systematically investigated. Notably, switching direction renders increase (207%) or a decrease (71%) in output comparison with non-poled counterpart. Theoretical modeling established combining Kelvin probe force microscopy characterization electron cloud overlap energy band derivation. This work not only offers unprecedented insight into fundamental mechanism but also opens up possibility development next-generation wearable electronics.

Unraveling the Energy‐Harvesting Performance of Antimony‐Doped BaTiO₃ Toward Self‐Powered on‐Body Wearable Impact Sensor

Energy Technology, Год журнала: 2025, Номер unknown

Опубликована: Март 5, 2025

Harvesting ambient mechanical energy from the environment has gained immense interest due to its application in harvesting and active sensing. Herein, an ABO 3 class ferroelectric semiconducting material BaTiO nanoparticles are used, Antimony (Sb) is used as a dopant, which can be able enhance piezoelectric coefficient of higher level, leading increased energy‐harvesting performances. The fabricated antimony‐doped barium titanate [Sb‐doped designated (BST)] then blended with polydimethylsiloxane (PDMS) prepare composite film. Electrodes attached film on either side fabricate flexible nanogenerator (FCF‐PENG) device. FCF‐PENG device generates maximum electrical output peak‐to‐peak 28 V 1.5 μA, respectively. also shows good power density 1.6 mW m −2 at load resistance 80 MΩ. At last, real‐time impact sensor was employ wearable sensor. detects high low upon human collision tested within laboratory values recorded monitored indicator using ESP32 microcontroller ThingSpeak cloud. above analysis experiments proved that paves way toward sports healthcare rehabilitation Internet Things (IoT) devices soon.

Abstract Bio‐inspired autonomous smart polydimethylsiloxane (PDMS) and its composite materials hold immense promise for a wide range of applications in electrical electronic devices. These mimic natural protective mechanisms with self‐healing, self‐reporting, self‐cleaning properties, enabling innovative efficient device design. Smart PDMS autonomously activate repair response to mechanical or damage, achieving rapid structural functional recovery preventing failure due the accumulation minor damage. can intuitively report their status through striking color changes, fluorescence, luminescence when exposed external stimuli, providing practical visual feedback health monitoring fault warning. They also have capacity effectively eliminate contaminants ice deposits from surfaces, thereby ensuring stable operation. This review aims introduce current research progress self‐cleaning, self‐reporting materials. The systematically discusses principles, methodological innovations, mechanistic analysis, these materials, highlighting significant potential field Moreover, provides an in‐depth analysis key challenges facing offers insights into future directions strategies.
