The field of machine health and system monitoring has gained interest in different application fields, e.g., monitoring of lubricants, vibrations, surroundings, environmental conditions or the temperature of critical machine parts. This work presents two different condition monitoring devices, which are fabricated in a low cost printing process directly on the non-planar surface of the object to be monitored. The first system is used for thermal condition monitoring, where temperature monitoring is performed by 24 thermocouples resulting in a 24 pixel temperature image of the sample. The thermocouples are printed in an array arrangement, which enables the reduction of the required electrical connections from 48 to 25. The second device is intended for the use in aerodynamic systems, e.g., airplane wings, rotor blades of wind turbines, and helicopters where icing is a critical issue. The aerodynamic lift of aircraft is critically influenced by deposits on the wing or rotor blade surface. Also in other rotor blade systems, e.g., wind turbines the efficiency is drastically dropped and in worst case the icing can cause the failure of the system. The aim is the fabrication of an active monitoring system which is able to detect and also remove the ice from the monitored surface. To this end the system is directly fabricated on the 3D shaped substrate like a wing or rotor blade and the icing is detected using a capacitive sensor and a thermocouple sensor array. In case of icing a heater removes the critical ice deposit.

直接打印在 3D 异形基板上的嵌入式温度和防冰监控系统

机器健康和系统监控领域在不同的应用领域引起了人们的兴趣，例如，监控润滑剂、振动、周围环境、环境条件或关键机器部件的温度。这项工作提出了两种不同的状态监测设备，它们是直接在要监测的物体的非平面表面上以低成本印刷工艺制造的。第一个系统用于热状态监测，其中温度监测由 24 个热电偶执行，产生样品的 24 像素温度图像。热电偶以阵列排列印刷，这使得所需的电气连接从 48 个减少到 25 个。 第二个设备旨在用于空气动力学系统，例如飞机机翼、风力涡轮机的转子叶片、以及结冰是一个关键问题的直升机。飞机的气动升力受到机翼或旋翼叶片表面沉积物的严重影响。同样在其他转子叶片系统中，例如风力涡轮机，效率急剧下降，在最坏的情况下，结冰会导致系统故障。目的是制造一个主动监测系统，该系统能够检测并去除被监测表面的冰。为此，该系统直接在 3D 形状的基板上制造，如机翼或转子叶片，并使用电容传感器和热电偶传感器阵列检测结冰。在结冰的情况下，加热器会去除关键的冰沉积物。同样在其他转子叶片系统中，例如风力涡轮机，效率急剧下降，在最坏的情况下，结冰会导致系统故障。目的是制造一个主动监测系统，该系统能够检测并去除被监测表面的冰。为此，该系统直接在 3D 形状的基板上制造，如机翼或转子叶片，并使用电容传感器和热电偶传感器阵列检测结冰。在结冰的情况下，加热器会去除关键的冰沉积物。同样在其他转子叶片系统中，例如风力涡轮机，效率急剧下降，在最坏的情况下，结冰会导致系统故障。目的是制造一个主动监测系统，该系统能够检测并去除被监测表面的冰。为此，该系统直接在 3D 形状的基板上制造，如机翼或转子叶片，并使用电容传感器和热电偶传感器阵列检测结冰。在结冰的情况下，加热器会去除关键的冰沉积物。为此，该系统直接在 3D 形状的基板上制造，如机翼或转子叶片，并使用电容传感器和热电偶传感器阵列检测结冰。在结冰的情况下，加热器会去除关键的冰沉积物。为此，该系统直接在 3D 形状的基板上制造，如机翼或转子叶片，并使用电容传感器和热电偶传感器阵列检测结冰。在结冰的情况下，加热器会去除关键的冰沉积物。
