摘　　要：We present here a 3D-printed pressure mapping mat,equipped with customizable architecture sensors,that offers a cost-effective and adaptable solution,overcoming the size constraints and sensing accuracy issues commonly associated with existing commercial pressure mats across various fields,such as healthcare and sports applications.Leveraging a pillar-origami structure,the demonstrated sensor offers multifaceted stiffness properties,effectively filtering skin deformations and enabling capacitive pressure sensing.Notably,the sensor’s detection range can be finely tuned,spanning from 70 to 2500 kPa,with a sensitivity range between 0.01 kPa^(−1) and 0.0002 kPa^(−1),and an impressive response time of just 800 milliseconds.Furthermore,the inclusion of a modular sensor array enhances maintenance and allows for greater flexibility in shaping and enhancing the device’s resolution.This technology finds practical applications in wireless foot pressure mapping and sports protection pads,marking a significant milestone in the advancement of flexible and custom-shaped pressure sensor technology.
