Chronic wounds affect millions of patients around the world and their treatment is challenging as the early signs indicating their development are subtle. In addition, a type of chronic wound, known as pressure ulcer, develops in patients with limited mobility. Infection and frequent bleeding are indicators of chronic wound development. In this article, we present an unprecedented low cost continuous wireless monitoring system, realized through inkjet printing on a standard bandage, which can send early warnings for the parameters like irregular bleeding, variations in pH levels and external pressure at wound site. In addition to the early warnings, this smart bandage concept can provide long term wound progression data to the health care providers. The smart bandage comprises a disposable part which has the inkjet printed sensors and a reusable part constituting the wireless electronics. This work is an important step towards futuristic wearable sensors for remote health care applications.
慢性伤口影响着全球数以百万计的患者，其治疗具有挑战性，因为早期的发病迹象很细微。此外，一种称为压疮的慢性伤口会在活动受限的患者中发生。感染和频繁出血是慢性伤口发展的指标。在本文中，我们提出了一种前所未有的低成本连续无线监测系统，该系统通过在标准绷带上喷墨打印来实现，可以对不规则出血、pH 值变化和伤口部位外部压力等参数发出早期预警。除了早期预警外，这种智能绷带概念还可以为医疗保健提供者提供长期的伤口进展数据。智能绷带包括一次性部分，其中具有喷墨打印传感器，以及可重复使用部分构成无线电子设备。这项工作是朝着远程医疗应用的未来可穿戴传感器迈出的重要一步。
