CONCLUSION AND OUTLOOK
This review explores the current state of flexible pressure sensor arrays, covering their working mechanisms,
materials, structural design, manufacturing methods and current challenges and strategies. Firstly, it
presents the background of sensor technology and the broad application prospects of flexible pressure
sensor arrays. It then mainly sums up and analyzes the research from anti-crosstalk design of multi-pixel
units, high-precision manufacturing technology for array structures, performance control methods for
miniaturized sensing units, to intelligent device array sensing applications. As a key technology in flexible
