“…In particular, composites with polymer matrices have potential applications in nanogeneration and energy harvesting [1][2][3][4], as well as ultrasonic transducers [5][6][7]. The addition of carbon nanotubes into such a system improves harvesting properties [8,9]. The composites comprising the mixture of ferroelectrics and ferromagnetics reveal the coupling of magnetic and electric polarizations [10,11].…”

Composite materials with 83 wt.% of the 0.7Pb(Mg1/3Nb2/3)O3-0.3PbTiO3 distributed in phosphate-bonded ceramics were prepared at three different pressures. A phosphate matrix comprises a mixture of an aluminum phosphate binder and melted periclase, MgO. All samples demonstrate a homogeneous distribution of the ferroelectric perovskite phase and are thermally stable up to 900 K. At higher temperatures, the pyrochlore cubic phase forms. It has been found that the density of the composites non-monotonously depends on the pressure. The dielectric permittivity and losses substantially increase with the density of the samples. The fabricated composites demonstrate diffused ferroelectric–paraelectric transition and prominent piezoelectric properties.

“…Due to the high piezoelectric coefficient and simple preparation process, the PENG with PZT fillers is the superior solution to realize the large-scale fabrication for converting mechanical energy to electrical energy [30,31]. In order to achieve a high-output PENG, carbon nanotubes (CNTs) with high surface area are added to the composite materials [32][33][34][35]. However, considering the phenomenon of the soft cluster caused by the Van Der Waals interactions, the composite PENGs doped with CNTs may appear uneven dispersion parts, which could reduce the conversion ability of mechanical-electrical energy within an active energy harvesting layer.…”

The development of stretchable nanogenerators has attracted intensive attentions for their promising applications in wearable electronics recently. Here, a newly high-performance stretchable PZT particles/Cu@Ag branch nanofibers (BNFs) nanocomposite piezoelectric generator (NCPG) is reported. The uniform mixture of PZT particles and Cu@Ag BNFs is blended into silicone rubber matrix that exhibits remarkably piezoelectric, mechanical and electrical characteristics. Owing to the similar molding method and the identical elastic matrix, the piezoelectric layer and the electrode layers could be completely integrated into stretchable NCPG based on all-in-one structure, which reveals high output performances (V peak-peak ≈61 V, I peak-peak ≈1.1 μA, 22.36 μw cm −3 ). The generated electricity is utilized to directly light five green emitting diodes (LEDs) and to drive a digital thermometer after stored in capacitor under the mechanical tensile strain stimulation. Moreover, the stretchable NCPG could act as a selfpowered body motion sensor for distinguishing the bending angles and frequencies of the knee joint. This work provides a novel design idea for stretchable nanogenerators and shows great potential applications in artificial intelligence, medical diagnosis and movement entertainment.
