Organometal Halide Perovskite Artificial Synapses

Advanced Materials, 2016
Organometal halide perovskite synaptic devices are fabricated; they emulate important working principles of a biological synapse, including excitatory postsynaptic current, paired-pulse facilitation, short-term plasticity, long-term plasticity, and spike-timing dependent plasticity. These properties originate from possible ion migration in the ion-rich

Microcontroller based artificial synapse

Proceedings of the IEEE 31st Annual Northeast Bioengineering Conference, 2005., 2005
This paper discusses a novel artificial synapse implementation utilizing a PIC microcontroller. This artificial synapse controls a postsynaptic neuron based upon the frequency of pulses input from a presynaptic neuron. The artificial synapse is constructed to interface the Lymnaea stagnalis neuron and a neuron emulator capable of simulating this type ...

Artificial electrical synapses in oscillatory networks

Journal of Neurophysiology, 1992
1. We use an electronic circuit to artificially electrically couple neurons. 2. Strengthening the coupling between an oscillating neuron and a hyperpolarized, passive neuron can either increase or decrease the frequency of the oscillator depending on the properties of the oscillator. 3.

Neuromorphic Synapses for Artificial Dendrites

Analog Integrated Circuits and Signal Processing, 1997
We describe neuromorphic, variable-weight synapses on artificial dendrites that facilitate experimentation with correlative adaptation rules. Attention is focused on those aspects of biological synaptic function that could affect a neuromorphic network‘s computational power and adaptive capability.

Stretchable Transistor‐Structured Artificial Synapses for Neuromorphic Electronics

Small, 2023
AbstractStretchable synaptic transistors, a core technology in neuromorphic electronics, have functions and structures similar to biological synapses and can concurrently transmit signals and learn. Stretchable synaptic transistors are usually soft and stretchy and can accommodate various mechanical deformations, which presents significant prospects in

Non‐linear Processing in Artificial Synapses

Kybernetes, 1992
Analyses the possibility of allowing non‐linear synaptic processing in Artificial Neural Networks (ANN) both theoretically and practically. The simple computer simulations described strongly suggest that this is a viable alternative, and preferable to ANN with just linear synapses, because of the savings in hardware (fewer components are needed) and ...
