Machines and electronic devices often generate waste heat that is difficult to utilize. If electricity could be generated from this waste heat, it would offer a means for a clean and sustainable power production: Such a technology would be ideally suited for low-power electronics applications such as wearables or low-cost Internet-of-Things devices. This includes, for example, wearable (medical) devices and sensors, with a wide range of applications in the healthcare and sports industry, in smart buildings and mobility applications.

Thermoelectric generators, machines that generate electricity by exploiting temperature di...

Edge Processing Research takes discovery closer to use in Artificial Intelligence Networks

Using the multimodal transistor (MMT) in artificial neural networks, which mimic the human brain, is an important step towards using thin-film transistors as artificial intelligence hardware.

Researchers at the University of Surrey have successfully demonstrated proof-of-concept of using their multimodal transistor (MMT) in artificial neural networks, which mimic the human brain.

This is an important step towards using thin-film transistors as artificial intelligence hardware and moves edge computing forward, with the prospect of reducing power needs and improving efficiency, rather than relying solely on computer chips.

The MMT, first reported by Surrey researchers in 2020, overcomes long-standing challenges associated with transistors and can perform the same operations as more...

Fully 3D-printed, Flexible OLED Display

The fully 3D-printed flexible organic light-emitting diode (OLED) display prototype is about 1.5 inches on each side and has 64 pixels. Every pixel works and displays light. The 3D-printed display is also flexible, which could make it useful for a wide variety of applications, such as foldable smartphone displays. Credit: McAlpine Group, University of Minnesota

Technology opens door to ubiquitous, more easily fabricated electronic screens. In a groundbreaking new study, researchers at the University of Minnesota Twin Cities used a customized printer to fully 3D print a flexible organic light-emitting diode (OLED) display...

Novel Memory Technology based on Compound Semiconductors

ULTRARAM device concept. a) Schematic cross-section of a device with corresponding material layers. The floating gate (FG), triple-barrier resonant-tunneling structure (TBRT), and readout channel are highlighted. Arrows indicate the direction of electron flow during program/erase operations. b) Scanning electron micrograph of a fabricated device of 10 Âµm gate length. c,d) Nonequilibrium Green’s functions (NEGF) calculations of density of states alongside conduction band diagrams for no applied bias (i.e., retention) and program-cycle bias respectively. B1, B2, and B3 are the AlSb barrier layers. QW1 and QW2 are the InAs quantum wells in the TBRT. Credit: DOI: 10.1002/aelm.202101103
