Abstract
We examine the factors controlling the neuromorphic response of organic electrochemical transistors (OECTs). In these devices, the gate voltage is used to supply the pre-synaptic input, while the drain current is taken as the post-synaptic output. We analyze the behavior of devices made from polymer blends of a mixed conductor (PEDOT:PSS) and an ion conductor (PSSNa). The experimental results highlight that the post-synaptic response timescale depends on the size of ion in the electrolyte. Modeling shows that the neuromorphic response is controlled by the transient response of the ionic circuit of the OECT. These insights on device response time pave the way for a more rational design of OECT-based neuromorphic devices.
