.../approach This design uses a flexible substrate, including four beams, mushroom-shaped composite cilia mounted on a central micro mass block, four Polyvinylidene fluoride piezoelectric films integrated on the beams and eight electrodes. The cilia receive sound pressure to drive the deformation of the beam...

... is to design a flexible tactile sensor array based on polyvinylidene fluoride ( PVDF ) piezoelectric film for plantar pressure measurement, which can simultaneously measure three-axis pressure, respectively, x-axis, y-axis, z-axis. Design/methodology/approach The sensor array...
