The Microsystems Technology Office at DARPA seeks fundamental research proposals for disruptive ideas in information and communication technologies (ICT) addressing the grand challenges for a data-driven future. Proposed research should investigate innovative approaches that enable revolutionary advances in science, devices, or systems. The goal of the Forward-Looking Experimentation (FLEX) program is to identify the direction and timing of key disruptive advances in ICT, accelerate technology exploration and generate intellectual property, develop next-generation researchers for the U.S. workforce, and build the foundation for future research programs.
