Kurzbeschreibung (Abstract)

Condition monitoring of machines and structural buildings enables the prediction of physical damage, preventing down-times in production, and ensuring the correct operation of critical infrastructure. Sensor-integrating machine elements (SiME) offer the ability to measure relevant quantities in situ while maintaining the standardized interface and function. Due to the requirement to preserve the machine element's structural integrity, the room for integrating sensors, evaluation electronics, and energy supply is limited by strict boundaries in diameter and height. Therefore, optimizing the size of every part is necessary. Here the use of a folded flexible Printed Circuit Board (PCB) allows to fully utilize the available space while ensuring manufacturability and assembly. This paper presents a flexible ultra-low power electronic platform for sensor-integrating bolts with multi-axis force and torque measurement. The platform is divided in two modules: a flexible printed circuit board carrying the precision measurement circuitry and the power supply/communication module on a rigid multilayer PCB. The modular platform reduces design risk and allows an evaluation of different power supply and communication concepts.
