Talk Title: Engineering Reverse Innovations: Using Emerging Markets' Constraints to Drive the Creation of High-Performance, Low-Cost, Global Technologies

Abstract: This presentation will demonstrate how the Global Engineering and Research (GEAR) Lab at MIT characterizes the unique technical and socioeconomic constraints of emerging markets, then uses these insights with engineering science and product design to create high-performance, low-cost, globally-relevant technologies. The talk will focus on three areas of GEAR Lab's research: high-performance, low-cost prosthetic feet: low-pressure, low-power drip irrigation, and solar-powered desalination. We have created a novel method of connecting the mechanical design of a foot to its biomechanical performance, which allows the stiffness and geometry to be optimized to induce able-bodied walking kinematics and kinetics. This theory has resulted in a single-part foot architecture which can be made of nylon to hit a $10 price point for developing countries, and which will be ruggedized and customizable for the US military/veteran population. By characterizing the coupled fluid/solid mechanics within drip irrigation emitters, we have designed new drippers that operate at 1/7th the pressure of existing products. This technology can cut the overall pressure, pumping power, and energy usage of drip irrigation systems by approximately 50%, and lower the capital cost of off-grid systems by up to 40%. GEAR Lab elucidated a disruptive market opportunity in arid countries for photovoltaic-powered electrodialysis (PV-ED) desalination, which requires half the energy and reduces water wastage from 60% to
