Due to the direct conversion between thermal and electrical energy, thermoelectric materials their devices exhibit great potential for power generation refrigeration. With rapid development of personal wearable electronics, design flexible inorganic receives increasing attention. As one most mature thin-film fabrication techniques, magnetron sputtering plays a key role in thin films devices, bu...

Poly (vinylidene fluoride) (PVDF) is a kind of semicrystalline organic polymer piezoelectric material. Adopting processes such as melting crystallization and solution casting, undergoing post-treatment annealing, stretching, polarization, PVDF films with high crystallinity response level can be realized. As material, shows excellent mechanical properties, chemical stability biocompatibility, li...
