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.
