Integrated Sensor Network with Event-Driven Activation for Recording Impact Events in Textile-Reinforced Composites

This paper presents the system concept and first experimental results of the realization of a sensor network for monitoring suddenly occurring temporary events such as impacts. The system consists of modules with sensor and transponder ASIC that can be integrated into a composite component made of glass fibers and polypropylene. The power consumption in standby is very low because the power supply for the ASICs is only activated when a relevant event is detected by a startup sensor. A fast start of the data acquisition process at the beginning of the event is therefore extremely important. The achievable startup time is demonstrated with a test setup.
