Abstract

This letter presents a monolayer onion epidermis as an ultrathin substrate for the development of dry electrodes used in electrical impedance spectroscopy (EIS), offering biocompatibility, flexibility, and high fidelity. The dry electrode is fabricated by sputtering a 100 nm layer of molybdenum onto the hydrophilic side of the epidermis membrane. Optical characterization confirms the structural integrity and quality of the thin metal film. Electrical characterization reveals a low sheet resistance of 151.28

, and experimental EIS studies demonstrate the electrode's enhanced electrical characteristics and capability to acquire impedance spectra from various fruits. In addition, durability tests over six months show comparable performance to commercial electrodes. This biocompatible electrode offrs a promising, cost-effective, and sustainable solution with reduced resource utilization, ideal for agrifood and wearable electronics applications.

农业食品应用的天然纤维素基柔性生物阻抗电极

本文介绍了一种单层洋葱表皮作为超薄衬底，用于开发电阻抗谱（EIS）中使用的干电极，具有生物相容性，灵活性和高保真度。干电极是通过在表皮膜的亲水侧溅射一层100nm的钼来制备的。光学表征证实了金属薄膜的结构完整性和质量。电学表征表明，该电极具有151.28 $\pm$ 0.08 $\Omega$/m$^{2}$的低片电阻，实验EIS研究表明，该电极具有增强的电学特性和获取各种水果阻抗谱的能力。此外，超过6个月的耐久性测试表明，其性能与商用电极相当。这种生物相容性电极提供了一种有前途的、具有成本效益的、可持续的解决方案，降低了资源利用率，是农业食品和可穿戴电子应用的理想选择。
