Controllers for Smart Skin Materials

SSC is developing a real-time active noise control system for use in smart materials applications. The architecture uses low cost digital signal processors that are integrated directly into a smart material. These computers enable a truly intelligent material that reacts to external stimuli and can adapt the materials' response to changing environmental conditions.

The computers are arranged in a hierarchical and distributed architecture that mimics the way biological systems achieve complex adaptive control of body movement.

An application of this technology is acoustic noise reduction for vehicles.

Applications

• Noise reduction for vehicles
• Acoustic Sensor Noise and Interference Reduction
• Noise Reduction for Wireless Communication
• Machine Tool Control

Controllers for Smart Skin Materials Objectives

• Demonstrate reduced acoustic noise in vehicles
• Reduce the controller cost of the smart skin relative to earlier achievements
• Reduce the thickness of the controller used in the smart skin relative to previous achievements.
