Researchers at the University of São Paulo (USP) in Brazil have developed a bioelectronic chip that simultaneously detects vitamins C and D in body fluids. It is flexible and easy to see and can be adapted for use in a wearable ...
When you need to measure white blood cell counts, it usually involves trips to clinics and expensive equipment for analysis. Likewise, checking water quality for contaminants can be a lengthy process.
It is a common hack to stretch a balloon out to make it easier to inflate. When the balloon stretches, the width crosswise shrinks to the size of a string. Noah Stocek, a Ph.D. student collaborating with Western physicist ...
Researchers at the University of São Paulo (USP) and the Federal University of Viçosa (UFV) in Brazil have developed a sustainable sensor that can be placed directly on the surface of a vegetable or fruit to detect the ...
For decades, people with diabetes have relied on finger pricks to withdraw blood or adhesive microneedles to measure and manage their glucose levels. In addition to being painful, these methods can cause itching, inflammation ...
Scientists from NTU Singapore have developed ultra-thin semiconductor fibers that can be woven into fabrics, turning them into smart wearable electronics. Their work has been published in the journal Nature.
New, highly stretchable sensors can monitor and transmit plant growth information without human intervention, report University of Illinois Urbana-Champaign researchers in the journal Device.
Researchers have developed a sensor made from "frozen smoke" that uses artificial intelligence techniques to detect formaldehyde in real time at concentrations as low as eight parts per billion, far beyond the sensitivity ...
A four-year study by Dartmouth researchers captures the most in-depth data yet on how college students' self-esteem and mental health fluctuates during their four years in academia, identifying key populations and stressors ...
Researchers at the Indian Institute of Science (IISc) have developed flexible films that exhibit bright colors purely by virtue of their physical structure, without the need for any pigment. When stretched, the films exhibit ...
