　　紧凑型移动式冷链温度监测系统的快速开发

　　精确的温度测量是在移动的应用范围从医疗设备到工业、医学的一个基本特征，医药冷链监测。对于这些应用程序，开发人员面临的挑战是设计解决方案，提供高精确度和可靠性，以最小的功耗、最小的可能占用率和最低的成本。

　　用典型的温度传感器设计，开发人员很难建立能够满足所有这些设计要求的信号链。然而，来自AMS的单芯片传感器提供了一个集成的解决方案，能够以最小的足迹在低功耗下提供高精度。

　　临界温度传感应用：冷链监测

　　精确的温度测量对于广泛的应用是至关重要的，即使是微小的温度变化也会影响性能。机械系统工作温度的意外偏差经常警告机械问题。化学反应速率随着温度的升高而增加，这就要求密切监测敏感化学和生化过程中的温度。甚至有专门的添加剂使用，能迅速降解的和不可逆的bioreactive材料暴露在他们的推荐范围之外的温度。敏感药品的安全递送依赖于整个供应链的定期温度测量——一个称为冷链监控的过程。

　　Among bioactive materials， vaccines are particularly sensitive to temperature. The World Health Organization notes that vaccines need to be stored between +2°C and +8°C， and any deviation outside of this range generally leads to loss of potency of the vaccine ［ref 1］。 Yet， according to the US Centers for Disease Control， occurrences of improper storage and handling continue to occur each year. Worse， a degraded vaccine cannot be detected through normal clinical methods. The result is not only financial loss due to wasted vaccine， but also the need to revaccinate affected individuals who received the compromised vaccine – a process that can damage public confidence in vaccine and health providers ［ref 2］.
