The $1 Water Sensor

[vc_row][vc_column][vc_column_text]Dr. Woo Jin Chang, Associate Professor, Mechanical Engineering, has developed a menu of miniature electrochemical sensors that can detect—at low-cost and instantaneously—heavy metals, water acidity, and nutrients in drinking water and other fluids. Three Wisconsin companies have licensed the sensor and now Chang and his...

Grant funds UWM research to mass-produce water sensors

A graphene-based water sensor developed at the University of Wisconsin-Milwaukee outperforms current technologies for sensing speed, accuracy and sensitivity – exactly what’s needed to continuously monitor drinking water for miniscule traces of contaminants like lead. But the cost of mass-producing these tiny sensors using traditional methods is high.
