为了实现信号处理与人体的融合，可穿戴和植入式射频/微波器件得到了迅速发展。然而，皮肤通用性和生物相容性的不足给这种装置的制造带来了挑战。在这项研究中，开发了一种超柔性和生物相容性的CoFeB/丝绸薄膜，有望用于皮肤和植入式射频/微波应用。此外，CoFeB/silk薄膜在水溶液中具有可控的溶解性，在环保一次性器件中具有很大的应用潜力。制备了一种基于CoFeB/silk薄膜的应变可调带阻滤波器，该滤波器具有3 GHz的大频率可调性，并具有监测手指关节运动的能力。这种将铁磁性材料与生物相容性衬底相结合的概念和方法为可穿戴/植入式应用提供了一种新的途径。
Aiming to realize the integration of signal processing with the human body, wearable and implantable radio frequency (RF)/microwave devices are rapidly developed. However, the insufficiency in skin commonality and biocompatibility brings up challenges in making such devices. In this study, an ultra-flexible and biocompatible CoFeB/silk film is developed potentially for on-skin and implantable RF/microwave applications. Moreover, the CoFeB/silk films present controllable dissolvability in aqueous solutions and exhibit great potentials in applications for environmentally friendly disposable devices. A strain-tunable bandstop filter based on the CoFeB/silk film was fabricated, which exhibited a large frequency tunability of 3 GHz and ability in monitoring the finger-joints’ motions. This concept and method of combining ferromagnetic materials with the biocompatible substrate offers a novel pathway for wearable/implantable applications.
