For instance, wearables not only monitor performance but also track physiological signs of stress or injury, allowing for prompt intervention.

例如，可穿戴设备不仅可以监测表现，还可以追踪压力或受伤的生理迹象，以便及时进行干预。

Scientists use a range of tools, from seismometers to satellite imagery, to track signs of unrest such as seismic activity, ground deformation, and gas emissions.

科学家使用从地震仪到卫星图像等一系列工具来追踪地震活动、地面变形和气体排放等动乱迹象。
