A Flexible Capacitive Paper-Based Pressure Sensor Fabricated Using 3D Printing

Flexible pressure sensors usually exhibit high sensitivity, excellent resolution, and can be mass-produced. Herein, a high-resolution, capacitive, paper-based, 3D-printed sensor with simple, low-cost preparation method is proposed. The has wide detection range (300–44,000 Pa), short response time (<50 ms), mechanical stability during repeated loading/unloading (3750 Pa). It measure the weight of an object precisely, from which shape predicted. also perform gait detection. advantages presented by low-cost, range, ability to mass-produced make these potential candidates for applications in contact wearable medical devices.
