The proposed project promotes a conceptual advance in the application of plate waves for the quantitative reconstruction of laminar defects by investigating fundamental experimental and analytical aspects of a novel approach in plate wave ultrasonic tomography. A successful development will have a comparable significance in the area of health monitoring of thin structures as computer tomography had in medical imaging. Previous attempts have ignored wave scattering effects, and therefore do not describe the correct physics of the problem. With its combined experimental-numerical approach, the proposed fundamental studies will help to identify the potential of plate wave ultrasonic tomography for in-situ health monitoring of realistic structures and smart materials design.Read moreRead less

Defying conventions with a liquid metal-embedded hybrid elastomer composite. Conductive elastic composites are one of the key components used in flexible/wearable electronic devices in the manufacture of sensors and interconnects; however, conventional composites experience a relatively low sensitivity to strain, and their conductivity decreases when stretched (i.e. they exhibit a negative piezoconductive effect).
