2024年3月22日 · Among CP-based devices, the organic electrochemical transistor (OECT) is particularly suitable for neural interfacing as a miniaturized amplifier of ionic signals. The OECT uses the CP in its channel gated through an aqueous electrolyte (such as the cerebrospinal fluid).

2024年12月4日 · DIW is an excellent approach for fabricating OECTs. This 3D printing method can be used to deposit the semiconductor layer, insulation layer, and contact electrodes.

2021年8月27日 · Organic electrochemical transistors (OECTs) are electrolyte-gated transistors, employing an electrolyte between their gate and channel instead of an insulating layer. For efficient gating, non-polarizable electrodes, for example, Ag/AgCl, are typically used but unfortunately, this simple approach limits the options for multiple gate integration.

OECTs are very effective in ion-to-electron transduction and sensor signal amplification. The use of synthetically tunable, biocompatible, and depositable organic materials in OECTs makes them specially interesting for biological applications and printable devices.
