Neuromorphic electronics aims to replicate the functionality of biological neurons, offering a promising route to energy-efficient data processing. One of the key application areas is bioelectronic interfacing, where neuromorphic systems can enable efficient, real-time analysis of biological signals at the edge. Organic electrochemical transistors (OECTs) are biocompatible, operate at low voltages, and support flexible, low-cost fabrication, making them ideal for bioelectronic interfaces and edge-processing in biosensing applications. Additionally, OECTs are particularly well-suited for such applications due to their unique ability to couple ionic and electronic transport for integration of electronic circuits with ion-driven biological systems.
Despite these advantages, implementing artificial neuron circuits that emulate the functional characteristics of their biological counterparts using organic materials remains a major challenge. In this work, we present an organic artificial neuron circuit based on a multivibrator – a well-known oscillatory circuit. The proposed neuron exhibits spiking activity with the ability of tuning intrinsic neuron excitability, which is considered to be involved in the learning process alongside synaptic plasticity. Apart from providing input-dependent spiking dynamics, the neuron demonstrates short-term memory based on its previous spiking activity. This study advances the development of accessible, neuromorphic hardware by introducing a new class of organic artificial neurons.

nanoGe is a prestigious brand of successful science conferences that are developed along the year in different areas of the world since 2009. Our worldwide conferences cover cutting-edge materials topics like perovskite solar cells, photovoltaics, optoelectronics, solar fuel conversion, surface science, catalysis and two-dimensional materials, among many others.
Previously nanoGe Spring Meeting (NSM) and nanoGe Fall Meeting (NFM), MATSUS is a multiple symposia conference focused on a broad set of topics of advanced materials preparation, their fundamental properties, and their applications, in fields such as renewable energy, photovoltaics, lighting, semiconductor quantum dots, 2-D materials synthesis, charge carriers dynamics, microscopy and spectroscopy semiconductors fundamentals, etc.
International Conference on Hybrid and Organic Photovoltaics
International Conference on Hybrid and Organic Photovoltaics (HOPV) is celebrated yearly in May. The main topics are the development, function and modeling of materials and devices for hybrid and organic solar cells. The field is now dominated by perovskite solar cells but also other hybrid technologies, as organic solar cells, quantum dot solar cells, and dye-sensitized solar cells and their integration into devices for photoelectrochemical solar fuel production.
Asia-Pacific International Conference on Perovskite, Organic Photovoltaics and Optoelectronics
The main topics of the Asia-Pacific International Conference on Perovskite, Organic Photovoltaics and Optoelectronics (IPEROP) are discussed every year in Asia-Pacific for gathering the recent advances in the fields of material preparation, modeling and fabrication of perovskite and hybrid and organic materials. Photovoltaic devices are analyzed from fundamental physics and materials properties to a broad set of applications. The conference also covers the developments of perovskite optoelectronics, including light-emitting diodes, lasers, optical devices, nanophotonics, nonlinear optical properties, colloidal nanostructures, photophysics and light-matter coupling.
The International Conference on Perovskite Thin Film Photovoltaics Perovskite Photonics and Optoelectronics (NIPHO) is the best place to hear the latest developments in perovskite solar cells as well as on recent advances in the fields of perovskite light-emitting diodes, lasers, optical devices, nanophotonics, nonlinear optical properties, colloidal nanostructures, photophysics and light-matter coupling.
