【 摘 要 】

tsContinuous piezoelectric BaTi0.88Sn0.12O3 (BTS) films were deposited on glass fiber fabrics successfully.Superflexible, highly sensitive self-powered piezoelectric sensors were fabricated based on polarization-free BTS.Low curie temperature would be a benefit for flexible piezoelectric sensors because small alterations of force will trigger large changes in polarization.The superflexible sensors are highly desirable for wearable devices to detect human motion.
