DOIAbstract
International audienceThis work presents a new pH sensor based on the architecture SGFET (Suspended Gate Field Effect Transistor). The pH variations are obtained using the threshold voltage and the transfer characteristics shift of the SGFET. To evaluate the accuracy and reliability of the pH sensor, pH variations were measured directly in the solution using both the SGFET and a commercial pH-meter
