With the advent of intelligent era, flexible piezoelectric tactile sensors, as key components for sensing information and transmitting signals, have received worldwide attention. However, pressure sensors are still currently limited, which severely restricts their practical applications. Furthermore, demonstrations conducted in labs not accurate to real-world scenarios. Thus, there is an urgent need further optimize intrinsic performance usage characteristics meet application requirements. As a representative piezoelectric, polyvinylidene fluoride (PVDF) exhibits significant advantages terms excellent flexibility, chemical stability, high electromechanical conversion, low cost, appropriate acoustic impedance, allow it serve core matrix sensors. This paper aims summarize very recent progress based on PVDF, including composition modulation, structure optimization, Based comprehensive summary studies, we propose rational perspectives strategies regarding PVDF-based provide some new insights research industrial communities.

In recent years, research on piezoelectric pressure sensing has attracted worldwide attention, as eagerly demanded by the development of wearable electronics. However, current sensors are unable to detect forces along different bending directions with a high resolution, thus limiting their applications in some typical scenarios. To address this issue, study designed novel composite structure ZnO nanorods loaded Ag nanoparticles (ZnONRs@Ag) and then embedded highly oriented polyvinylidene fluoride (PVDF) fibers. Due its unique orientation, sensor exhibits anisotropy, accurately identifying distinct (such perpendicular, parallel, or twisting). The optimized PVDF/ZnONRs@Ag device presents peak power density 308.1 nW cm-2 sensitivity 0.52 V N-1 remains stable after 7000 cycles at 1.4 Hz. devices utilized monitor various human movements harvest energy from them. This provides viable method for manufacturing self-powered directional sensors, contributing advancement technology harvesting applications.
