A large class of chemical and biological sensors have been based on electrical characterization of interfaces where sensing is often related to the characterization of interfaces between ion‐based and electron‐based conductive materials by means of typical electric variables such as voltage, current and charge. Integrated electronics has started a revolution in this field allowing very complex electronic systems to be shrunk to millimeter square sizes. This paper will introduce some recent trends in integrated sensor interface design, showing how progress in electronic devices and signal processing would enhance performance and applications of biochemical sensors.
