An artificial kidney with its own measuring system

A Leti research team working under the FP7 Nephron project has developed an embedded system for measuring the concentrations of key dialysis solution ions (like sodium, calcium, potassium, phosphorus, and urea) before and after the solution passes through an artificial kidney. This measuring system includes a five-electrode electrochemical sensor and control software to test the equipment and characterize the sensors.
The main innovation in Leti’s measuring system is that it is embedded: an electronic chip converts the pressure data recorded by the sensors into ion concentrations. Moreover, the system can run on just 4 mA of current, meaning that it does not need to be plugged into a power supply.
