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. This gap can passively and adaptively change with the intensity of laryngeal vibration: during strong vibration, the repulsion force surges to prevent contact saturation, while during weak vibration, a small local gap is maintained to preserve high sensitivity. This invention solves the problems of uneven magnetic force and discomfort in traditional magnetic repulsion schemes through all-thin film fabrication and patterned magnetization technology, achieving a balance between high signal fidelity, wide dynamic range, and ultimate wearing comfort, making it particularly suitable for wearable artificial laryngeal speech acquisition systems.
