In recent years, piezoelectric polymer sensors are used in energy harvesting and self-powered sensing due to their flexibility, low density, high constant, performances may be improved through a careful architectural design. Herein, we reported facile strategy for fabricating core–sheath fiber (C-PEF) by directly electrospinning poly(vinylidene fluoride) (PVDF) onto the stainless steel wires. Such C-PEF can well respond bending deformation with different degrees, therefore it assembled into sensor airflow speed sensing. Furthermore, spring-like structured (S-C-PEF) serve as spring sophisticated manner monitor human sleep behavior. This work paves way developing multigeometric though low-cost, facile, reliable method, showing potential applications including health monitoring.
