The worldwide spread of COVID-19 has forced us to adapt to a new way of life made of social distancing, avoidance of physical contact and temperature checks before entering public places, in order to successfully limit the virus circulation. The role of technology has been fundamental in order to support the required changes to our lives: thermal sensors, in particular, are especially suited to address the needs arisen during the pandemic. They are, in fact, very versatile devices which allow performing contactless human body temperature measurements, presence detection and people counting, and automation of appliances and systems, thus avoiding the need to touch them. This paper reviews the theory behind thermal detectors, considering the different types of sensors proposed during the last ten years, while focusing on their possible employment for COVID-19 related applications.
新冠病毒病（COVID-19）在全球的传播迫使我们适应一种新的生活方式，这种生活方式包括保持社交距离、避免身体接触以及在进入公共场所前进行体温检测，以便成功限制病毒传播。为了支持我们生活所需的这些变化，技术发挥了至关重要的作用：特别是热传感器，非常适合满足疫情期间出现的需求。事实上，它们是非常多功能的设备，能够进行非接触式人体体温测量、存在检测、人数统计以及电器和系统的自动化操作，从而避免了触摸这些设备的必要性。本文回顾了热探测器背后的理论，考虑了过去十年中提出的不同类型的传感器，同时重点关注它们在与新冠病毒病相关应用中的可能用途。
