Techniques to develop novel synthetic materials, processes and sensors through advanced understanding and exploitation of design principles found in nature. [ 10:2592] NOTE: An example includes genetically engineered high-strength silk fibers. These fibers, which are about 5 microns in diameter, are 100-percent tougher than Kevlar aramid fibers.
