Dendritic Organic Electrochemical Transistors Grown by Electropolymerization for 3D Neuromorphic Engineering
It is shown how bipolar electropolymerization can be used to engineer 3D networks of PEDOT:PSS dendritic fibers and revealed that quasi‐static and transient response of OECTs can be adjusted by controlling dendrites’ morphologies.
Gas diffusion layer from Binchotan carbon and its electrochemical properties for supporting electrocatalyst in fuel cell
The gas diffusion layer (GDL) in the fuel cell has been made from carbon dispersion electrochemically deposited from binchotan. We prepared GDL by spraying the ink on the surface of the conductive
Implantable Organic Artificial Synapses Exhibiting Crossover between Depressive and Facilitative Plasticity Response
An artificial synapse, made of intracortical microelectrodes, is demonstrated that exhibits either depressive or facilitative STP, and the proposed RLC circuit explains the physical origin of the observed STP and its two timescales in terms of charge build up in PEDOT/PSS.
Compact setup for SIMO measurements of slab interconnects and correlation with PEDOT:PSS nanostructure morphology
We demonstrate a compact, portable and reliable, poor-man’s 8-channel interconnect and measure, in the 50- 100MHz VHF radiofrequency range, the path-dependent voltage transfer function across
Application of neural networks in recognition of complex solutions
This thesis will test the applicability of neural networks in recognition of blends of different Na, K, and Ca concentrations which could provide basis in investigating other more advanced neuromorphic topics.


Diffusion Driven Selectivity in Organic Electrochemical Transistors
This work model the transient behavior of an OECT considering the effect of diffusion of the target species in the electrolyte and develops a general method that can be used to differentiate and distinguish different molecules from a complex mixture, on the basis of their diffusivity and thus mass.
Steady‐State and Transient Behavior of Organic Electrochemical Transistors
In recent years, organic electrochemical transistors (OECTs) have emerged as attractive devices for a variety of applications, particularly in the area of sensing. While the electrical
