A flexible tactile sensor with microdome array structures is proposed in this paper. The structure characteristics, fabrication process and micro characterization of the tactile sensor with microdome array structures are researched, and the tactile perception mechanism is also revealed with ANSYS finite element analysis software. The force sensitive characteristic of the microdome array structures flexible tactile is studied and the application of plantar pressure distribution perception is illustrated. The experimental results indicate that the microdome array structures flexible tactile has good force-sensitive property and wearing comfort, and it provides a design proposal for flexible wearable tactile sensor.
