At the recent IEEE International Electron Devices Meeting (IEDM) in San Francisco, imec and Holst Centre debuted a miniaturized sensor that simultaneously determines pH and chloride (Cl-)levels in fluid. This innovation is a must have for accurate long-term measurement of ion concentrations in applications such as environmental monitoring, precision agriculture and diagnostics for personalized healthcare.   The sensor is an industry first and due to the SoC (system on chip) integration, it ena...
