摘要

现代3d打印技术使复杂机械结构的快速成型成为可能。我们利用这一能力，通过在打印过程中结合软性和铁磁性长丝来创建可定制的压力传感器。由此产生的电感传感器利用基于体心立方单元格的晶格结构，具有可调刚度，杨氏模量范围为112至368 kPa，灵敏度范围为$-$0.17至$-$0.11% kPa$^{-1}$。传感器显示最小的迟滞，并在10000次压缩循环中保持稳定。这种方法的多功能性通过一个完全印刷的感应操纵杆的制造进一步证明。

Inductive Pressure Sensors Using 3D-Printed Structures With Tunable Stiffness

Modern 3-D printing techniques enable the rapid prototyping of complex mechanical structures. We leverage this capability to create customizable pressure sensors by combining soft and ferromagnetic filaments during the printing process. The resulting inductive sensors utilize a lattice structure based on a body-centered cubic unit cell, exhibiting tunable stiffness with Young's moduli ranging from 112 to 368 kPa and sensitivities between

0.17 and

0.11% kPa

. The sensors show minimal hysteresis and remain stable throughout 10 000 compression cycles. The versatility of this approach is further demonstrated through the fabrication of a fully printed inductive joystick.
