Magnetoelectric (ME) composites offer strain-mediated coupling between the ferroelectric matrix and ferromagnetic filler. They also find their application in magnetic field sensors, energy harvesters, and biomedicine.[1, 2] The requirement of flexible devices with the advent of the internet of things (IoT) and Industry 4.0 has increased. Therefore, we report a co-polymer polyvinylidene fluoride-trifluoroethylene P(VDF-TrFE) based ME composite here. Reduced functional properties are often a case for ME polymeric composites due to the magnetic filler's low resistivity and the formation of long-range conducting paths.[3-5] As a remedy, we fabricated a dual-phase magnetic filler having magnesium hydroxide Mg(OH)2 nanoplates acted as template material for localized growth of Fe3O4 nanoparticles on the template surface during a single-pot hydrothermal reaction. The optimized spin-coated film MFPT5 has filler loading of 5wt%, and we obtained an enhanced ferroelectric polarization value for MFPT5 than that of the pristine film, MFPT0. The leakage current was reduced, and the crystallinity of the MFPT5 film was also increased. Therefore, the work discussed here paves the way to develop ME composites with low leakage current to obtain a multifunctional material. Finally, we characterized the magnetic behavior of MFPT5 films and exploited them for triboelectric nanogenerator (TENG) application and detection of stray magnetic fields of electrical appliances. Thus, the proposed ME sensor can assure the safety of working personnel at industries by detecting the magnetic field of heavy machinery and sending a signal to their wearable devices.

nanoGe is a prestigious brand of successful science conferences that are developed along the year in different areas of the world since 2009. Our worldwide conferences cover cutting-edge materials topics like perovskite solar cells, photovoltaics, optoelectronics, solar fuel conversion, surface science, catalysis and two-dimensional materials, among many others.
Previously nanoGe Spring Meeting (NSM) and nanoGe Fall Meeting (NFM), MATSUS is a multiple symposia conference focused on a broad set of topics of advanced materials preparation, their fundamental properties, and their applications, in fields such as renewable energy, photovoltaics, lighting, semiconductor quantum dots, 2-D materials synthesis, charge carriers dynamics, microscopy and spectroscopy semiconductors fundamentals, etc.
International Conference on Hybrid and Organic Photovoltaics
International Conference on Hybrid and Organic Photovoltaics (HOPV) is celebrated yearly in May. The main topics are the development, function and modeling of materials and devices for hybrid and organic solar cells. The field is now dominated by perovskite solar cells but also other hybrid technologies, as organic solar cells, quantum dot solar cells, and dye-sensitized solar cells and their integration into devices for photoelectrochemical solar fuel production.
Asia-Pacific International Conference on Perovskite, Organic Photovoltaics and Optoelectronics
The main topics of the Asia-Pacific International Conference on Perovskite, Organic Photovoltaics and Optoelectronics (IPEROP) are discussed every year in Asia-Pacific for gathering the recent advances in the fields of material preparation, modeling and fabrication of perovskite and hybrid and organic materials. Photovoltaic devices are analyzed from fundamental physics and materials properties to a broad set of applications. The conference also covers the developments of perovskite optoelectronics, including light-emitting diodes, lasers, optical devices, nanophotonics, nonlinear optical properties, colloidal nanostructures, photophysics and light-matter coupling.
The International Conference on Perovskite Thin Film Photovoltaics Perovskite Photonics and Optoelectronics (NIPHO) is the best place to hear the latest developments in perovskite solar cells as well as on recent advances in the fields of perovskite light-emitting diodes, lasers, optical devices, nanophotonics, nonlinear optical properties, colloidal nanostructures, photophysics and light-matter coupling.
