The fabrication of self-powered pressure sensors based on piezoelectric materials requires flexible piezoelectric generators produced with a continuous, large-scale, and environmentally friendly approach. In this study, continuous poly(vinylidene fluoride) (PVDF) sheets with a higher β-phase content were facilely fabricated by the melt-extrusion–calendering technique and a PVDF-based piezoelectric generator (PEG) was further assembled. Such a PEG exhibits a remarkable piezoelectric output performance. Moreover, it possesses prominent stability even after working for a long time, exhibiting potential applications for real-time monitoring of various human movements (i.e., hopping, running, and walking) and gait. This work not only provides the possibility of continuous and environmentally friendly fabrication of PVDF sheets with remarkable piezoelectric properties but also paves a new promising pathway for powering portable microelectronic applications without any external power supply.

用于自供电压电传感的 β 相富集 PVDF 片材的制造
基于压电材料的自供电压力传感器的制造需要采用连续、大规模和环保的方法生产柔性压电发电机。在这项研究中,通过熔融挤出-压延技术轻松制造了具有较高β相含量的连续聚偏氟乙烯(PVDF)片材,并进一步组装了基于PVDF的压电发电机(PEG)。这样的PEG表现出显着的压电输出性能。此外,它即使在长时间工作后也具有显着的稳定性,在实时监测各种人体运动(即跳跃、跑步和步行)和步态方面具有潜在的应用价值。
