汗液监测是一种有效的程序，以发现早期迹象或前兆的一些心理物理疾病。本文提出了一种紧凑的无线柔性皮肤pH传感器，用于在UHF波段与辐射识别集成。其特点是它的简单性和所需电子元件的最小量。该设备包括印刷的多层pH传感器和能量收集天线，其针对应用于人体皮肤进行了优化。初步实验表明，该设备能够捕获与生理数据兼容的pH范围，并在不需要电池的情况下交换长达1米的数据。
Sweat monitoring is an effective procedure to detect early signs or precursors of some psychophysical diseases. A compact wireless flexible on-skin pH sensor is here proposed for integration with Radiofrequency Identification in the UHF band. The peculiarity is its simplicity and minimal amount of required electronic components. The device comprises a printed multilayer pH sensor and an energy harvesting antenna optimized for application onto the human skin. Preliminary experiments demonstrated that the device is capable to capture a pH range compatible with physiologic data and to exchange data up to 1m without need of battery.
