Development of an artificial vision device capable of mimicking human optical illusions

Posted: 29 Nov 2021 07:56 AM PST

Researchers have developed an ionic artificial vision device capable of increasing the edge contrast between the darker and lighter areas of an mage in a manner similar to that of human vision. This first-ever synthetic mimicry of human optical illusions was achieved using ionic migration and interaction within solids. It may be possible to use the device to develop compact, energy-efficient visual sensing and image processing hardware systems capable of processing analog signals.

Origami, kirigami inspire mechanical metamaterials designs

Posted: 23 Nov 2021 10:13 AM PST

Researchers categorize origami- and kirigami-based mechanical metamaterials, artificially engineered materials with unusual mechanical properties, and subdivided them into rigid or deformable categories based on the elastic energy landscape. The researchers want to discover new designs, especially curved origami designs, hybrid origami-kirigami designs, modular designs, and hierarchical designs; to design for real-world applications, it will be helpful to explore materials with different properties such as thin or thick, soft or hard, and elastic or plastic.

Fighting blood diseases with artificial intelligence

Posted: 22 Nov 2021 10:55 AM PST

How can we better diagnose blood diseases? A research group aims to answer this question with artificial intelligence (AI). Their goal is to facilitate the time-consuming analysis of bone marrow cells under the microscope. The researchers developed the largest open-source database on microscopic images of bone marrow cells to date. They use it as the basis for an AI model with high potential for routine diagnostics.

Wearable device can detect and reverse opioid overdose
