Obtaining robust power density through piezoelectric nanogenerators (PENGs) is very challenging. Challenges include achieving good mechanical stability, optimum stiffness, reasonable voltage generation, limited heat dissipation, and as needed. This work focused exactly on these areas, hybrid filler emerged a promising candidate among the composites studied. For example, fillers exhibited optimized properties suitable for self-powered engineering applications. The fabricated in this were based titanium oxide (TiO2), molybdenum disulfide (MoS2), silicone rubber (SR) host matrix. results showed that TiO2 represents reinforcing filler, while MoS2 exerts lubricating effect, improving composites' strength elongation at break. compressive modulus 8 per hundred parts of (phr) was 2.39 MPa 1.62 2.1 (hybrid filler). Similarly, hysteresis loss 5 phr 20.09 J/m 21.56 20.48 Moreover, break 150% 194% 170% In same way, electro-mechanical obtained also robust. output ~22 mV ~35 ~46 PENGs developed generated power. ~0.55 pW/cm2 ~1.03 ~1.56 Finally, coefficient 40 pC/N 112 160 These materials have role energy harvesting portable electronic systems. low-power provide cost-effective management circuits. allows to contribute sustainable self-sufficient systems like pacemaker implants.
