Summary: Novel hybrid nanogenerators (HNG) with multifunctional materials are gaining immense interest due to their high electrical output and broad applications in the electronic industry. The intrinsic hybridization of single electrode triboelectric (SE-TE) and piezoelectric (PE) nanogenerators (NGs), known as double layered (DL)-HNG, can eliminate the real-time electrical grounding issues and produce high output. The DL-HNG, made of Cu2O-doped 0.3Ba(0.7)Ca(0.3)TiO(3)-0.7BaSn(0.12)Ti(0.88)O(3) nanoparticles (Cu2O-BCST NPs) and polydimethylsiloxane polymer, can be scaled up to work as a flexible self-powered trackpad or touch sensor.

Summary: Recently, phase change chalcogenides, particularly monochalcogenides, have shown potential as switching materials for conduction-bridge-based memristors. However, previous studies have mainly focused on the formation and rupture of an Ag filament during the SET and RESET processes, disregarding the contributions of the phase change phenomenon and the distribution and re-distribution of germanium vacancies defects. In this study, GeTe-based devices with different thicknesses were investigated, revealing the effectiveness of phase loops and defect loops for future applications in neuromorphic computing. The electrical characteristics of the devices were examined, and it was found that a 100 nm-thick GeTe device exhibited highly reproducible phase change and defect-based characteristics, while 70 nm and 200 nm-thick devices were not suitable for reliable memory performance. Further analysis of the 100 nm-thick GeTe device revealed a state-of-the-art dependency of phase loops and defect loops on the starting and stopping voltage sweeps applied on the top Ag electrode, providing a deeper understanding of the switching mechanism of monochalcogenide-based conduction-bridge memristors.

Summary: This study presents a method to enhance data processing by integrating a unidirectional analogue artificial neuromorphic memristor device with a piezoelectric nanogenerator, taking inspiration from biological information processing. A self-powered unidirectional neuromorphic resistive memory device is proposed, comprising an ITO/ZnO/Yb2O3/Au structure combined with a high-sensitivity piezoelectric nanogenerator (PENG) ITO/ZnO/Al. The integration enables the creation of a self-powered artificial sensing system that converts mechanical stimuli from the PENG into electrical signals, which are subsequently processed by analogue unidirectional neuromorphic device to mimic the functionality of a neuron without requiring additional circuitry. This emulation encompasses crucial functions such as potentiation, depression, and synaptic plasticity. Furthermore, this study highlights the potential for hardware implementations of neural networks with a weight change of memristor device with nonlinearity (NL) of potentiation and depression of 1.94 and 0.89, respectively, with an accuracy of 93%. The outcomes of this research contribute to the progress of next-generation low-power, self-powered unidirectional neuromorphic perception networks with correlated learning and trainable memory capabilities.
