Abstract

The invention discloses a multifunctional flexible tactile sensor and a preparation method thereof. The multifunctional flexible tactile sensor with a novel structure is obtained by introducing the elastic layer and the flexible sensing layer and adopting a multi-layer fitting assembly method, the elastic layer is provided with the micro-bulge array for conducting mechanical information and the through hole array for conducting temperature information, the flexible sensing layer comprises a pressure sensing unit array, a temperature sensing unit array and a flexible insulating substrate, and the surface of the flexible insulating substrate is provided with a planar electrode array. The structure can realize multifunctional detection of tactile information such as pressure, sliding and temperature by the sensor, realizes real-time detection of spatial distribution of the tactile information by the sensor, and overcomes the defect of single measurement function of a tactile sensing device in the prior art. The sensor can be directly worn at the tail end of a finger of the manipulator and acquire tactile information of the manipulator in real time, and has the characteristics of array, multiple functions, wearable performance, low cost and customizability.
