This invention discloses an artificial laryngeal sensor based on magnetic repulsion coupling of a dual-layer heterogeneous magnetic thin film and its fabrication method. The sensor includes upper and lower sensing units, each having a first flexible magnetic layer that has been directionally magnetized and a flexible hard magnetic thin film layer that has been patterned and magnetized to form a microscopic magnetic domain array. The two layers, with their like poles facing each other, generate a uniform magnetic repulsion force, forming a dynamically adjustable gap between the triboelectric layers.
