Abstract Flexible sensors, a significant and rapidly developing field within technology, are primarily constructed from flexible materials, enabling the detection of physical variables while retaining remarkable flexibility. These sensors have demonstrated substantial potential and significant application value across numerous domains. In this work, the polyurethane sponge (PU) was selected as the substrate, and the MWCNTs-CCTO porous flexible capacitive pressure sensor was prepared by ultrasonic immersion treatment technology. This sensor exhibits high sensitivity (0.954 kPa^-1), excellent repeatability and stability, and is capable of detecting minute pressures, showcasing commendable pressure sensing capabilities. It is poised to revolutionize applications in areas such as motion signal monitoring and human-computer interaction.

Key words： flexible pressure sensor multi walled carbon nanotubes copper calcium titanate motion signal monitoring human-computer inte-raction
