A two-terminal floating-gate transistor for neuromorphic computing
Researchers at Technion and TowerJazz in Israel have recently built a low-power, two-terminal floating-gate transistor that could have useful applications in neuromorphic computing. This transistor, presented in a paper in Nature Electronics, was fabricated using...
Teaching AI agents navigation subroutines by feeding them videos
Researchers at UC Berkeley and Facebook AI Research have recently proposed a new approach that can enhance the navigation skills of machine learning models. Their method, presented in a paper pre-published on arXiv, allows models to acquire visuo-motor navigation...
Flexible organic electrodes built using water-processed silver nanowires
Organic electronic devices, which are made of small molecules or polymers (i.e., substances composed primarily or completely of similar units bound together) are known to have several advantageous properties. In fact, organic electronics have relatively low production...
Hourglass-shaped silicon photodiodes with an enhanced near-infrared photoresponse
Silicon photodiodes are semiconductor devices commonly used to detect visible light and measure its intensity, color and position. The fact that these devices are made of silicon has both advantages and disadvantages.
Batteries with fluorinated electrolytes that work at very high and low temperatures
Electrolytes are chemical components that enable the flow of ions between the cathode and anode inside batteries, ultimately providing electrical power to technological devices. Most conventional and readily available non-aqueous Li-ion batteries are fabricated using...
An ultra-stretchable triboelectric strip sensor (TSS) to control objects in 3-D space
Nanogenerators, technological tools that can convert mechanical or thermal energy into electricity, come in three key designs: piezoelectric, triboelectric and pyroelectric. While piezoelectric and triboelectric nanogenerators can convert mechanical energy into...
An ultrathin nanoelectromechanical transducer made of hafnium zirconium oxide
Recently developed nanomechanical resonators that can operate at super-high (i.e., three to 30 GHz) and extremely high (30 to 300 GHz) frequency regimes could be extremely valuable for the development of more advanced semiconductor electronics such as wideband...
A new smartphone user authentication system based on gait analysis
A team of researchers at the University of Pretoria and City University of Hong Kong has recently developed a continuous smartphone user authentication system based on gait analysis. This system, outlined in a paper presented at the 44th annual conference of the IEEE...
A ferroelectric ternary content-addressable memory to enhance deep learning models
Most deep-learning algorithms perform well when trained on large sets of labeled data, but their performance tends to decline when processing new data. Researchers worldwide have thus been trying to develop techniques that could improve the ability of these algorithms...
