Abstract
Flexible piezoelectric composite films, flexible piezoelectric impact sensors, pedestrian protection systems, and related methods. Such a flexible piezoelectric composite film includes a flexible matrix and a plurality of piezoelectric particles dispersed and embedded within the flexible matrix. The piezoelectric particles are arranged in columns aligned in a Z-direction along a thickness of the flexible matrix.
