Monitorization of gait‐related parameters is of the utmost importance to prevent complications in several diseases, ensuring affordable healthcare for the growing amount of chronic, lifestyle‐related diseases and also for improving motion performance. Sensorized insoles allow to both pressure data and gait timings to be extracted non‐intrusively in a point of care paradigm. Laser‐induced graphene (LIG) offers a path to the integration of sensors in different kinds of materials, including cork, a common insole material. In this work, piezoresistive sensors are developed by providing conductivity to natural cork and agglomerate cork through the direct synthesis of LIG by UV irradiation. Highly isotropic conductive LIG regions with less than 100 Ω sq⁻¹ are patterned and their piezoresistive response for up to 1132 kPa is assessed with sensitivities up to 0.02 kPa⁻¹. A low‐cost prototype insole is devised and tested, proving the potential of this kind of functional cork as a green alternative for gait analysis platforms.

直接在软木鞋垫上合成激光诱导的石墨烯压阻传感器进行步态分析

步态相关参数的监控对于预防多种疾病的并发症，为越来越多的慢性，与生活方式有关的疾病确保负担得起的医疗保健以及改善运动表现至关重要。感应鞋垫可以在护理点范式中以非侵入方式提取压力数据和步态时间。激光诱导石墨烯（LIG）提供了一种将传感器集成到不同种类的材料中的途径，其中包括软木塞（一种常见的鞋垫材料）。在这项工作中，通过通过紫外线辐射直接合成LIG，为天然软木和附聚软木提供导电性，从而开发了压阻传感器。小于100Ωsq ^-1的高各向同性导电LIG区域对其进行图案化，并以高达0.02 kPa ^-1的灵敏度评估高达1132 kPa的压阻响应。设计并测试了一种低成本的原型鞋垫，证明了这种功能性软木塞作为步态分析平台的绿色替代品的潜力。
