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 GoalDevelop a sensor embedded into a strong, self lubricating, diamond like carbon (DLC) coating.
