This paper proposes the concept of how machinery condition monitoring can be taken to the next level, through micro-sensing of tribological phenomena occurring between contacting surfaces. By considering wear transitions and wear rates it is possible to distinguish between benign and potentially harmful wear scenarios. By measuring the tribological phenomena associated with these conditions, it should then be possible to determine with greater accuracy the health of a machine at any point in its life. For this approach to succeed, it is necessary to develop a comprehensive and holistic monitoring strategy and target sensing technologies for the key wear factors. The paper has two main sections. Firstly, tribological phenomena and the onset of wear which sets out why and what needs to be monitored. The factors influencing the wear process are grouped into three key areas: lubricant condition, tribo-pair condition and operating condition. Through a critical and comprehensive review of developing and state-of the-art tribo-sensing, the second section identifies the potential technologies for monitoring or measuring the physical parameters within these three groupings and thus sets out how the next generation of machine condition monitoring will need to evolve in order to achieve early wear detection and the related benefits.

本文提出了一种概念，即通过对接触表面之间发生的摩擦学现象进行微感应，可以将机械状态监测提升到一个新的水平。通过考虑磨损过渡和磨损率，可以区分良性磨损情况和潜在有害磨损情况。通过测量与这些条件相关的摩擦学现象，那么应该可以更准确地确定机器在其寿命中任何时候的运行状况。为了使这种方法成功，有必要针对关键磨损因素制定全面而全面的监测策略和目标传感技术。本文有两个主要部分。首先，摩擦学现象和磨损的发生阐明了为什么以及需要监测什么。影响磨损过程的因素分为三个关键区域：润滑条件，摩擦副条件和工作条件。通过对发展中和最先进的摩擦感测的关键和全面的回顾，第二部分确定了用于监视或测量这三个组中的物理参数的潜在技术，从而阐明了下一代机器状态监视将如何进行。为了实现早期磨损检测和相关的好处，需要不断发展。
