Abstract Smart flooring embedded with TENG technology enhances safety and security in dream homes by generating energy through movement, providing real‐time alerts monitoring capabilities. Research on smart is limited, particularly concerning its washability, which remains a significant drawback. To tackle this challenge, an innovative solution developed that not only washable but also flexible durable, combining barium titanate (BT) graphite fluorinated polymer (FG) within Ecoflex (EC) matrix, utilizing sandwich‐style single‐electrode (SWSE‐TENG) configuration. This design exhibits remarkable triboelectric performance, achieving open‐circuit potential of 1000 V short‐circuit current 25 µA when tapped nitrile‐glove‐clad hand. Extensive testing under various conditions such as humidity, water immersion, frequent washing demonstrates outstanding stability resilience. The SWSE‐TENG shows promising applications safety, security, athletic environments. Prior to this, EC‐BT‐FG composites varying BT FG concentrations using facile casting technique are fabricated, systematically analyzing their structural, crystalline, electrical properties. Notably, the 5 wt% EC composite (EC‐5‐5) superior making it optimal choice for solution.

Abstract Integration of triboelectric nanogenerators (TENGs) with water splitting offers a promising approach for generating green hydrogen from mechanical energy. However, the development efficient TENGs is challenged by significant losses. To enhance sustainable energy harvesting, it crucial to minimize these losses and improve tribo‐polarities. Recent advancements in incorporating conductive fillers have proven effective improving performance. In this study, new class bifunctional amino surface‐modified graphene oxide (MGO) synthesized graphite powder introduced. The MGO filler enhances positive polarity polymer through groups while reducing loss due inherent conductivity graphene. Incorporating 1.5 wt.% into silk electrospun membranes (1.5SMGO) boosted surface positivity +695 +1905 V, surpassing unmodified (GO) (+1220 V), highlighting impact modification. resulting TENG 1.5SMGO exhibits an open circuit voltage 1135 V current density 11.76 mA m − 2 , demonstrating its effectiveness as harvester low‐power electronics. Additionally, proposed can serve source water‐splitting, enabling production. Thus, MGO‐based holds potential self‐powered wearable electronics water‐splitting applications.
