We report the first proof-of-concept demonstration of fully 3D-printed, transistor-like, no-moving-parts switches capable of performing logic operations. The devices are monolithically made via material extrusion using copper nanoparticle-reinforced PLA and pure PLA. The enabling mechanism is a newly discovered, temperature-induced, reversible spike in resistivity that narrow, 3D-printed conductive traces experience when carrying current over a specific threshold. The operation of the proposed device is demonstrated through the successful implementation of the first fully 3D-printed logic gates, and through its use as a switch to actuate a DC motor. This work represents a major leap towards the monolithic fabrication of intelligent, semiconductor-free, integrated electromechanical devices by enabling the 3D printing of active electronics. © 2023 IEEJ.

We report the design, fabrication, and characterization of the first monolithically 3D-printed, three-dimensional, three-material, cored inductors for use in compact electromagnetic systems. Additive manufacturing technologies can produce functional, freeform-compatible mechanical devices;however, the ability of additive manufacturing to create electronic components that could enable the monolithic fabrication of devices that integrate sensors and actuators is still unfulfilled. This study aims at advancing the state of the art through the demonstration of the first truly three-dimensional, monolithically 3D-printed, cored solenoids. The novel 3D-printed inductors are made via material extrusion using three PLA-based materials (dielectric, conductive, and soft magnetic). The devices attain Gauss-level magnetic fields while drawing tens-of-milliamps currents. The work is of great interest for fast and inexpensive fabrication of compact sensors, actuators, and power conversion systems, and for the integration of electronics with MEMS devices of intricate geometries. © 2023 IEEE.

Gallium nitride (GaN)-based high electron mobility transistors (HEMTs) currently define the state-of-the-art in high power density, radiofrequency (RF) semiconductor devices. However, there remain many relatively unexplored areas of penetration for GaN electronics, including high temperature (HT) electronics applications such as Venus exploration, hypersonic flight, jet engines, automotive vehicles, chemical plants, and geothermal energy [1]. Due to their low intrinsic carrier concentration, wide-bandgap semiconductors such as silicon carbide (SiC) and gallium nitride are fundamentally better suited for HT operation. GaN technology is especially promising over SiC due to its higher mobility, greater critical field, and wider bandgap [2]. Furthermore, there has already been many excellent recent demonstrations of HT GaN based devices [3] - [8] © 2024 IEEE.

GaN complementary transistors (CT) are highly desirable for GaN integrated circuits with low static power dissipation [1]. While recent experiments studied the feasibility of GaN CT [2 , 3] and improved GaN p-channel field effect transistor (p-FET) [4 , 5] , further advancements, e.g. in high temperature (HT) operation, would fully realize the potential of this emerging technology. HT operation (> 300°C, beyond the Si CMOS limit) is necessary to ensure its reliability at high power, harsh environment applications, and reduced thermal management needs. The degradation of electrode metal and gate dielectric was found to be the main challenge of GaN devices for HT operation [6 , 7]. © 2024 IEEE.

There is a growing demand for real-Time image denoising in low-light shooting with ultra-high definition cameras. This paper presents a denoising method that incorporates Haar-wavelet shrinkage denoising and a minimum mean square error estimation based on an extension of the Noise2Noise learning technique, which can perform low-latency processing and can be adapted to non-linear processed signals without prior knowledge of noise and signal distributions. By introducing a two-dimensional kernel to reduce memory usage in the coring function estimator, we demonstrate real-Time hardware denoising for luminance signals of 4K 60 fps video with a delay of less than one millisecond. © 2024 IEEE.

It is fascinating how our body receives an immense amount of sensory information through numerous receptors distributed throughout the body and efficiently integrates it to make decisions for daily activities, while maintaining extremely low energy consumption and cognitive load. This bioinspired sensory information processing paradigm offers unparalleled advantages over traditional von Neumann architectures due to its exceptional energy efficiency, fault tolerance, and adaptability. While previous efforts in this area have mainly focused on the development of biomimetic sensors, it is equally important to create a computing architecture that can process sensory data locally before transmitting it to a higher level. The strategy of offloading computation at the edge can significantly reduce data latency, saving transmission bandwidth and relieving the burden of computation at a higher level, just like the way our peripheral nervous system complements the central nervous system.

Encoder-Decoder Calibration for Multimodal Machine Translation

IEEE Transactions on Artificial Intelligence

The main purpose of multimodal machine translation (MMT) is to improve the quality of translation results by taking the corresponding visual context as an additional input. Recently many studies in neural machine translation have attempted to obtain high-quality multimodal representation of encoder or decoder via attention mechanism. However, attention mechanism does not always accurately identify the decisive input for each prediction, which leads to an unsatisfactory multimodal information fusion. To this end, we propose an encoder-decoder (Enc-Dec) calibration method which can automatically calibrate the image and text fusion representation in the encoder, and find the decisive input to the translation in the decoder. We validate our model on the MMT dataset Multi30K. Experimental results show that our method significantly outperforms several recent baselines for both English-German and English-French translation tasks in terms of BLEU and METEOR. © 2020 IEEE.
