Inside Front Cover: Trilayered Ceramic–Metal–Polymer Microcantilevers with Dramatically Enhanced Thermal Sensitivity (Adv. Mater. 9/2006)



A novel trilayered (ceramic–metal–polymer) design for highly sensitive, thermally responsive microcantilever arrays is reported on p. 1157 by Tsukruk and co-workers. In this design, the topmost nanocomposite layer, reinforced with carbon nanotubes and silver nanoparticles, acts as a strong thermal-stress-driven actuator to enhance conventional biomaterial performance. These polymer–metal–ceramic microcantilevers with enhanced (fourfold) thermal sensitivity may serve as a basis for the next generation of uncooled thermal microsensor arrays because of outstanding thermal and spatial resolution.
