Organic Electrochemical Transistors for Clinical Applications
Advanced Healthcare Materials, 2014The ability of organic electrochemical transistors is explored to record human electrophysiological signals of clinical relevance. An organic electrochemical transistor (OECT) that shows a high (>1 mS) transconductance at zero applied gate voltage is used, necessitating only one power supply to bias the drain, while the gate circuit is driven by ...

Active Materials for Organic Electrochemical Transistors
Advanced Materials, 2018AbstractThe organic electrochemical transistor (OECT) is a device capable of simultaneously controlling the flow of electronic and ionic currents. This unique feature renders the OECT the perfect technology to interface man‐made electronics, where signals are conveyed by electrons, with the world of the living, where information exchange relies on ...

Organic electrochemical transistors for biosensing
Organic and Hybrid Sensors and Bioelectronics XIV, 2021Conjugated polymers provide a unique toolbox for establishing electrical communication with biological systems. In the first half of this talk, I will introduce the type of conjugated polymers used at the biological interface. I will then show how we designed organic electrochemical transistors (OECTs) for protein detection at the physical limit and ...

Neuromorphic Functions in PEDOT:PSS Organic Electrochemical Transistors
Advanced Materials, 2015Depressive short-term synaptic plasticity functions are implemented with a simple polymer poly(3,4ethylenedioxythiophene):poly(styrene sulfonate) (PSS) organic electrochemical transistor device. These functions are a first step toward the realization of organic-based neuroinspired platforms with spatiotemporal information processing capabilities.

Validation of the organic electrochemical transistor for in vitro toxicology
Biochimica et Biophysica Acta (BBA) - General Subjects, 2013The gastrointestinal epithelium provides a physical and biochemical barrier to the passage of ions and small molecules; however this barrier may be breached by pathogens and toxins. The effect of individual pathogens/toxins on the intestinal epithelium has been well characterized: they disrupt barrier tissue in a variety of ways, such as by targeting ...
