ON THE GOVER: Macroelectronics. While the integrated-circuit industry strives ta make the smallest possible devices in the smallest possible area, the field of "macroelectronics" addresses applications that conventional microelectronics cannot: active contrai circuitry in situ, over areas of up ta many square meters, for displays, solar panels, x-ray imagers, surface measurements, structural shape contrai, vehicle health monitoring, and other large-scale systems. Examplesinclude (upper left) large-area active-matrix liquid-crystal displays (AMLCDs, photo courtesy of D.G. Hopper), and (lower right) printed electronics using electrically functional inks applied ta a paper or plastic substrate (rolls shawn are 2500 ft long and 18 inches in diameter). See the technical theme that begins on p. 447.
Aiso in this issue is a special feature on bio- materials for drug delivery and tissue engineering by Robert Langer (MIT), recipient oi the 2005 Von Hippel Award. Shawn here is a polymer-based microsphere for drug deliveryapplications [diameter, 1000 ~m; from MY Sefton, L.R. Brown, and R.S.
Langer, J. Pharm. Sei. 73 (1984) p. 1859]. Seethe special feature that begins on p. 477.
