Referenceless pH Sensor using Organic Electrochemical Transistors

Abstract : Using printing techniques, organic electrochemical transistors are integrated in a differential bridge. This circuit allows biochemical sensing without the use of a reference electrode. Electrodeposited iridium oxide gate electrodes enable pH measurements with increased sensitivity, also demonstrated in complex biological media such as human sweat.
