Researchers from the Technical University of Madrid and the University of Florence have created a robotic fish that can monitor the pH levels of water. As team member Giovanna Marrazza explained to Digital Trends, the robot swims according to directives sent in form of chemical messengers: “The concentration of hydrogen ions in the environment is detected by an electrochemical multi-sensor platform. The acquired signal is then transformed into an electronic signal to be used in robot electronics control.” The robot can detect areas of acidity or pollutant concentration, and swim in their direction to investigate them further.
