<p>Wearable self-powered piezoelectric pressure sensors are attracting tremendous interest. However, fabricating a high-sensitive elastic piezoelectric sensor for a broad response range remains challenging. Here, we assemble polar poly(vinylidene fluoride) (PVDF) microsphere-elastomer composites, achieving high-sensitive and wide-responsive pressure sensing. The polar PVDF microspheres are produced cost-effectively through phase separation, enabling scalability. The piezoelectric composite (PC) film demonstrates low Young’s modulus, and excellent anti-fatigue performance. Further, the PC-based piezoelectric sensor exhibits a rather high sensitivity of 540 mV N⁻¹ in a wide sensing range (5–40 N), 240 times greater than the PVDF film-based sensor and comparable to the inorganic piezoelectric sensor. Such excellent performance is attributed to the highest average stress concentration on the spherical PVDF coupled with the remarkable deformation of dipoles of spherical PVDF in the flexible matrix. Based on excellent performance, this piezoelectric sensor achieves precise recognition of motions and sound visualization. This high-sensitive flexible piezoelectric sensor enabling large area production with ultralow price exerts great potential in smart monitoring and intelligent robots.</p>
