We have developed an innovative recyclable printed magnetoresistive sensor using GMR microflakes and AMR microparticles as functional fillers, with PECH as the elastomer binder. Under saturation magnetic fields of 100 mT and 30 mT, these sensors respectively exhibit magnetoresistance values of 4.7% and 0.45%. The excellent mechanical properties and thermal stability of the PECH elastomer binder endow these sensors with outstanding flexibility and temperature stability. This flexibility, low cost, and scalability make these sensors highly suitable for integration into flexible electronic devices, such as smart security systems and home automation. Moreover, these sensors are fully recyclable and reusable, allowing the materials to be separated, reused, and remanufactured without loss of performance. The low energy consumption of the production process and the recyclability of the materials significantly reduce the environmental impact of these magnetic field sensors.
我们开发了一种创新的可回收印刷磁阻传感器，使用巨磁电阻（GMR）微片和各向异性磁电阻（AMR）微粒作为功能填料，以聚（2-乙基-2-恶唑啉）（PECH）作为弹性体粘合剂。在100 mT和30 mT的饱和磁场下，这些传感器分别表现出4.7%和0.45%的磁阻值。PECH弹性体粘合剂优异的机械性能和热稳定性赋予这些传感器出色的柔韧性和温度稳定性。这种柔韧性、低成本和可扩展性使这些传感器非常适合集成到柔性电子设备中，如智能安全系统和家庭自动化设备。此外，这些传感器完全可回收和重复使用，材料能够被分离、再利用和再制造，而不会损失性能。生产过程的低能耗和材料的可回收性显著降低了这些磁场传感器对环境的影响。
