Applications of the Technology
• Monitoring Sensor placement, in critical areas• Fatigue of structures e.g. Composites and
Joints – – Bonding and Fasteners– Detection of bond integrity from 0-100%– Changes in condition e.g. weakening joints
• Analysis using latent or imposed forces e.g. heat, mechanical, pressure or vibration excitation.
