Automation of phenotypic measurements of livestock has become a more important goal for scientists and also for farmers who need a more precise, real-time knowledge of their animals. Among physiological measures, body temperature and its variations are key indicators of the physiological health and well-being of animals. Although measuring the body temperature may seem a trivial matter, its implementation is faced with many difficulties both at biological and technological levels in a field of constant progress. Today, there are many studies reporting taking temperature measurements without restraining animals. The present report focuses on the two main approaches to temperature measurements that use direct contact or radiation sensors. Specifically, we investigated the use of thermocouples, thermistors and infrared radiation sensors. A wide literature review using one of these techniques was conducted in which different animal species, different purposes, different experimental designs, various equipments, and different devices and gold standard methods are discussed. These technologies will continue their dizzying development, leading to new communication protocols, sensors miniaturization and a more efficient management of energy. These developments will have a direct impact on the increase of reading distances and the amount of information stored. In response to the request of farmers and researchers, integrated monitoring systems are already marketed with user-friendly interfaces and softwares for complex data storage and treatments.

Introduction. The analytical researches of methods and devices of determination of thermophysical properties of complicated structure and chemical composition of products of processing industry are carried out in order to increase the accuracy of measurements. Materials and methods. The basis of the studied devices is thermoelectric converters of temperature and heat flow in the form of "auxiliary wall". To improve the accuracy of the measurements of the thermophysical characteristics of materials, the graph-analytical method of calibration of the devices was used. Results and discussion. To study the thermophysical characteristics of thermolabial materials, the most suitable thermometric means of their complex definition, which allow to conduct research in the presence or absence of material phase transformations of its constituents. The calorimetric measuring instruments are based on the measurement of the temperature of the heat fluxes that penetrate the sample under different thermal conditions. Thermal, electric and other transmission processes in thermometric materials determine the instability of the transformation function and form an instrumental error. On the basis of the calculation and graphic analysis of the thermal and capacitive resistance of the "device-sampler" system, a fundamentally new method has been developed, according to which the thermophysical characteristics of the material and the metrological characteristics of the device are determined in a complex and simultaneously based on the results of the experiment with samples of only the test material. Conclusion. Simultaneous obtaining information on the values of the thermophysical characteristics of the material and the metrological characteristics of the device can improve the accuracy of the determination of the thermophysical characteristics of products.

“…In addition to traditional thermocouples, the rapid development of microelectromechanical system (MEMS) technology has enabled thin-film thermocouples (TFTCs) that possess the advantages of small heat capacity and fast response. 56 , 57 , 58 , 59 , 60 , 61 As shown in Figure 1 , flexible TFTCs not only inherit the advantages of traditional TFTCs, but also exhibit the characteristics of flexible sensors. 16 , 22 , 62 TFTCs are deformable, ultralight, ultrathin, portable, and can be easily attached, making them suitable for application in wearables.…”
