‘Lensless’ Imaging through Advanced Machine Learning for Next Generation Image Sensing Solutions

The targets are the images displayed on an LCD screen (left two columns) and the objects in the wild (right two columns; beckoning cat doll and stuffed bear), respectively. The first row shows the ground truth images displayed on the screen and the shooting scenes for in-the-wild objects. The second row shows the captured patterns on the sensor. The last three rows illustrate the reconstructed images by the proposed, model-based, and CNN-based methods, respectively. The proposed method produces the most high-quality and visually appealing images. Credit: Xiuxi Pan from Tokyo Tech

A camera usually requires a lens system to capture a focused image, and the lensed camera has been the dominant imaging solution for centuries...

A research team from Chemnitz and Dresden has taken a major step forward in the development of sensitive electronic skin (e-skin) with integrated artificial hairs. E-skins are flexible electronic systems that try to mimic the sensitivity of their natural human skin counterparts. Applications range from skin replacement and medical sensors on the body to artificial skin for humanoid robots and androids. Tiny surface hairs can perceive and anticipate the slightest tactile sensation on human skin and even recognize the direction of touch...

Scientists use Recycled Glass Waste as Sand Replacement in 3D printing

Researchers from Nanyang Technological University, Singapore (NTU Singapore) have developed the capability to use recycled glass in 3D printing, opening doors to a more environmentally sustainable way of building and construction.

Glass is one material that can be 100 per cent recycled with no reduction in quality, yet it is one of the least recycled waste types. Glass is made up of silicon dioxide, or silica, which is a major component of sand, and therefore it offers significant untapped potential to be recycled into other products.

At the same time, due to growing populations, urbanisation and infrastructure development, the world is facing a shortage of sand, with climate scientists calling it one of the greatest sustainability challenges of the 21st century.

For these re...

Exotic Magnetic Structures created with Laser Light

Research at Lund University in Sweden has found a new way to create nano-sized magnetic particles using ultrafast laser light pulses. The discovery could pave the way for new and more energy-efficient technical components and become useful in the quantum computers of the future.

Magnetic skyrmions are sometimes described as magnetic vortices. Unlike ferromagnetic states — which occur in conventional magnets such as compasses and refrigerator magnets — the skyrmion state is quite peculiar: the orientation of the magnetization does not point in the same direction everywhere in the material, but is instead best described as a kind of swirling magnetism.

Skyrmions are of great interest to both basic researchand industry, as they can be used to manufactu...
