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).
