There is one component that virtually any embedded wearable needs—a power source. This paper proposes an energy source, which contains no harmful substances, can be stored in a stand-by dry state for indefinite time period, is flexible and has tactile characteristics similar to that of textile. The main feature of this energy source is the separation of the electrolyte and the electrodes—the electrolyte is applied only when the battery needs to be activated. This makes storage time in a dry state virtually infinite. It expands their potential use to storage solutions and healthcare/health monitoring solutions, because the design of the battery allows it to be used as an active sensor, which generates electric current, when it detects liquid. We stress that this solution is suitable for specific applications only, outlined in the paper. The main components of the battery include aluminium anode, air cathode and the cotton shell. The design includes only textile-based materials, which ensure greater flexibility and better fusion with textile materials, where the battery is intended to be integrated. Besides that, results of the experiments with multi-cell battery prototype are presented.

柔性纺织铝空气电池原型的开发

实际上,任何嵌入式可穿戴设备都需要一个组件-电源。本文提出了一种能源,该能源不含有害物质,可以无限期地处于待机干燥状态,具有柔韧性,并且具有类似于纺织品的触觉特性。这种能源的主要特征是电解质和电极的分离-仅在需要激活电池时才应用电解质。这使得在干燥状态下的存储时间实际上是无限的。它将其潜在用途扩展到存储解决方案和医疗保健/健康监测解决方案,因为电池的设计使其可以用作有源传感器,当它检测到液体时会产生电流。我们强调,该解决方案仅适用于白皮书中概述的特定应用。电池的主要组件包括铝阳极,空气阴极和棉壳。该设计仅包含基于纺织的材料,可确保更大的灵活性并更好地与打算集成电池的纺织材料融合。除此之外,还给出了多电池原型的实验结果。
