The invention belongs to the technical field of flexible pressure sensors, and discloses a multi-layer microstructure flexible pressure sensor with a gradient structure and a preparation method and application thereof. According to the preparation method, ITO/PET is selected as a flexible substrate and an electrode, a microstructure graphite-PDMS composite film is prepared to serve as a pressure sensitive material, a flexible pressure sensor with a gradient structure and a multi-layer microstructure is designed, the structure simulates the gradient structure from an epidermal layer to a corium layer of the skin of a human body, the contact area of the composite material is increased through the multi-layer design, and the pressure sensitive performance of the sensor is improved. And the sensitivity and the linear sensing range are improved. The preparation method is simple to operate, low in cost and easy to implement, and has a wide application prospect in the field of flexible pressure sensors. 本发明属于柔性压力传感器
