Temporally Reconfigurable Reservoir Computing with Flexible Electrolyte‐Gated TFTs for High‐Performance Neuromorphic Processing

Advanced Materials, EarlyView.
A temporally reconfigurable reservoir computing system is developed using ultrathin, flexible, all‐solid‐state electrolyte‐gated thin‐film transistors (UFLEX TFTs). By simply tuning temporal dynamics electrically, the system achieves 93.7% accuracy for MNIST handwritten digits, 90.3% for CIFAR‐10 images, and 81.8% for chest X‐rays, surpassing CNNs in ...

A three‐phase three‐level converter with shared flying capacitors

IET Power Electronics, EarlyView., 2023
Three‐phase multilevel converters use a high number of components which increases their size. As specific weight reduction is a work of interest for embedded system applications, this paper presents a topology aiming to optimize volume and mass for a three‐level three‐phase inverter. The number of passive and active components is reduced thanks to the ‘
