Holograms Supercharge Nanoscale 3D Printing

Using holograms, a nano-scale 3D printer can now rapidly fabricate complex items with details smaller than a wavelength of visible light, a new study finds. This new research can rapidly manufacture nanotechnological arrays of wires, lenses, rotating magnetic gears, and other structures—suggesting applications in electronics, photonics, micro-robotics and more.Currently, the…

Hybrid Memristor AI Chips Could Scale

By combining atomically thin devices with conventional microchips, scientists have created brain-mimicking hybrid electronics that can help implement neural network artificial intelligence systems in a far more energy-efficient way than standard electronics, a new study finds.As electronics become tinier and tinier, scientists are investigating atomically thin 2D materials for next-generation…

Dry EEG Sensors Control Army Robots

Brain-machine interface (BMI) technology, for all its decades of development, still awaits widespread use. Reasons include hardware and software not yet up to the task in non-invasive approaches that use electroencephalogram (EEG) sensors placed on the scalp, and because surgery is required in approaches relying on brain implants.Now, researchers at,…

Robo-Honeycomb Reveals the Secret Lives of Bees

Interactive robotics is a relatively new field of study, but in a short time has moved on from just performing pre-programmed repetitive tasks to more complex activities, including interactions with living creatures. Biocompatible and biomimetic robots, for example, are being increasingly used to study animals and plants. Animal-in-the-loop robotic systems…
