Neurogenic bladder and other lower urinary tract dysfunctions represent a significant health hazard and life‐quality impairment in individuals suffering from neurological disorders. A few implantable and wearable technologies have been proposed to partially recover bladder functionality, mostly based on resistive and capacitive strain gauges designed to be surgically placed inside the pelvic cavity. In this work, an alternative proof‐of‐concept device for monitoring the volumetric changes of the bladder is presented, where the sensing element is based on a capacitive linear encoder integrated with a passive wireless radio‐frequency resonator, which can be remotely interrogated. The sliding mechanism at the core of the proposed system allows a wide sensing range without stringent requirements on materials properties and overall device stability.

迈向用于膀胱体积实时编码的无芯片无线被动系统

神经源性膀胱和其他下尿路功能障碍代表患有神经系统疾病的个体的重大健康危害和生活质量损害。已经提出了一些可植入和可穿戴的技术来部分地恢复膀胱功能，主要是基于电阻和电容应变仪，这些应变仪被设计为通过手术放置在骨盆腔内。在这项工作中，提出了一种用于监视膀胱体积变化的替代性概念验证设备，其中传感元件基于集成了无源无线射频谐振器的电容线性编码器，可以远程询问。所提出系统的核心滑动机构允许宽范围的感应，而对材料特性和整体设备稳定性没有严格的要求。
