Researchers at Waterloo Engineering have combined new artificial intelligence (AI) software with low-cost testing tools to enable communities in the developing world to routinely monitor water quality.
The technology builds on work previously done by Sushanta Mitra, an engineering professor who heads the Waterloo Institute for Nanotechnology, and post-doctoral fellow Naga Siva Kumar Gunda on inexpensive kits to test for potentially deadly E. coli bacteria.
“We brought two disciplines together,” says Mitra. “One is biochemistry and the other is a mathematical tool, a convolutional neural network.”
