This contribution summarizes the current state of research regarding so‐called sensor‐integrating machine elements as an enabler of digitalization in mechanical engineering and——if available—their application in industry. The focus is on the methodical aspects of the development of these machine elements in general as well as specific sensor‐integr...

Comprehensive data on machines is essential for digitization in the industry. Since standardized machine elements are used in most machines, integrating them with sensors provides the opportunity to acquire data comprehensively from in-situ. The sensor integration must not change the element’s core function and the standardized mechanical interface...

Standardized fasteners such as bolts are particularly suitable for structurally integrated force measurements, as they are located directly in the force flow and therefore allow the monitoring of the overall system status in-situ via the multi-axis components of the acting forces. Available solutions are either tailored to specific applications or...

We present a multi-axis force sensor capable of measuring both axial forces and bending moments that is integrable into a cavity within a M20 bolt. This cavity, which reduces the resilience of the bolt by 23.5 %, and, thus, corresponds to a reduction by only one strength class, is designed by conducting a finite element analysis. The force sensor f...

Sensor-integrating machine elements (SiME) are essential enablers for digitization in the industry. There are major challenges in the development of SiME as an interdisciplinary mechatronic system, requiring methodical support. In this work, we address these challenges and aim to provide methods and tools by analyzing the state-of-the-art and ten o...
