Online Monitoring of Composites with a Miniaturized Flexible Combined Dielectric and Temperature Sensor

Online Monitoring of Composites with a Miniaturized Flexible Combined Dielectric and Temperature Sensor

We present a foil based miniaturized impedance sensor combined with a temperature sensitive structure to be integrated in Carbon-Fiber-Reinforced-Polymer (CFRP). Commercially available sensors are too big and they weaken the CFRP. In contrast the influence of our miniaturized flexible sensor can be...
