COSMOS Components and Smart Machines with Micro-Nano Surface Embedded Sensors

The Vision Improved interaction between human and machines. Smart machines with imbedded sensors will improve safety, lifetime and performance. Short periods with improper operation with critical parameters may be avoided. Create intelligent surfaces of the future.

The Goal Develop a sensor embedded into a strong, self lubricating, diamond like carbon (DLC) coating. Substrate CCr-CrN layer CVD DLC Embedded Sensor

Cross-disciplinary task Surface embedded sensors Sensor design and technology DLC coating technology 3D structurization Interface: Wiring and electronics Sensor test Coating test
