Abstract

The following relates generally to ion sensing using organic electrochemical transistors (OECTs). In one aspect, a device comprises: an amplification portion including an OECT; a feedback portion that receives a differential voltage from the amplification portion and outputs a feedback signal; and a readout portion which receives the feedback signal and outputs an output voltage.
