Only 2% of women working in the United States science, tech, engineering, and math (STEM) fields are Hispanic, according to the National Science Foundation. But that chronic under-representation hasn’t stopped Hispanic women from inventing. Brazilian María Angélica Camargo invented a quick and affordable Dengue fever test that helped save many lives in Brazil and other affected areas. Colombian María Alexandra Tamayo has invented what she calls the NanoPro. This device helps filter and kill fungi, bacteria, and viruses in water, making it safe to drink, perfect for areas without potable water. Then there is Olga Gonzalez-Sanabria, from Puerto Rico. She developed a long-life nickel-hydrogen battery that powers satellites in space. There are many more examples of female inventors battling the odds to bring the benefits of their inventions to the world.
