The need for hydration monitoring is significant, especially for the very young and elderly populations who are more vulnerable to becoming dehydrated and suffering from the effects that dehydration brings. This need has been among the drivers of considerable effort in the academic and commercial sectors to provide a means for monitoring hydration status, with a special interest in doing so outside the hospital or clinical setting. This review of emerging technologies provides an overview of many technology approaches that, on a theoretical basis, have sensitivity to water and are feasible as a routine measurement. We review the evidence of technical validation and of their use in humans. Finally, we highlight the essential need for these technologies to be rigorously evaluated for their diagnostic potential, as a necessary step to meet the need for hydration monitoring outside of the clinical environment.
监测水合作用的需求非常重要，特别是对于非常年幼和年长的人群，他们更容易脱水，并受到脱水带来的影响。这种需求一直是学术界和商业界大力推动提供监测水合状态的手段的动力之一，特别关注在医院或临床环境之外进行监测。本综述介绍了许多新兴技术，这些技术从理论上讲对水具有敏感性，并且可以作为常规测量方法使用。我们回顾了技术验证的证据及其在人体中的应用。最后，我们强调了这些技术必须经过严格评估其诊断潜力，这是满足临床环境外水合作用监测需求的必要步骤。
