Ion‐Selective Organic Electrochemical Transistors

Advanced Materials, 2014
Ion-selective organic electrochemical transistors with sensitivity to potassium approaching 50 μA dec(-1) are demonstrated. The remarkable sensitivity arises from the use of high transconductance devices, where the conducting polymer is in direct contact with a reference gel electrolyte and integrated with an ion-selective membrane.

Benchmarking organic electrochemical transistors for plant electrophysiology [PDF]

Frontiers in Plant Science, 2022
Plants are able to sense and respond to a myriad of external stimuli, using different signal transduction pathways, including electrical signaling. The ability to monitor plant responses is essential not only for fundamental plant science, but also to gain knowledge on how to interface plants with technology. Still, the field of plant electrophysiology

High‐Performance Vertical Organic Electrochemical Transistors [PDF]

Advanced Materials, 2017
AbstractOrganic electrochemical transistors (OECTs) are promising transducers for biointerfacing due to their high transconductance, biocompatibility, and availability in a variety of form factors. Most OECTs reported to date, however, utilize rather large channels, limiting the transistor performance and resulting in a low transistor density.

Diffusion Driven Selectivity in Organic Electrochemical Transistors [PDF]

Scientific Reports, 2014
Organic Electrochemical transistors (OECTs) present unique features for their strategic combination with biomedical interfaces, simple and low voltage operation regime and sensing ability in aqueous environment, but they still lack selectivity, so that a significant effort in research is devoted to overcome this limitation.
