Wearable human sweat sensor monitors chemicals in real-time
Researchers at the Hefei Institutes of Physical Sciences in China have developed a wristwatch capable of long-term monitoring of key ions in human sweat, led by Prof. HUANG Xingjiu.
Biodegradable sensor monitors levels of pesticides via direct contact with surface of fruit and vegetables
From Fundação de Amparo à Pesquisa do Estado de São Paulo 04/02/24 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 presence of pesticides. Known for […]
Let it glow: Scientists develop new approach to detect ‘forever chemicals’ in water
From University of Birmingham 23/01/24 Researchers have created a new way to detect ‘forever chemical’ pollution in water, via a luminescent sensor. Scientists in Chemistry and Environmental Science at the University of Birmingham in collaboration with scientists from the Bundesanstalt für Materialforschung und -prüfung (BAM), Germany’s Federal Institute for Materials Research and Testing, have developed […]
Brazilians create sensor to monitor levels of widely used antibiotic in water and food
From Fundação de Amparo à Pesquisa do Estado de São Paulo 25/12/23 Researchers at the Center for Development of Functional Materials (CDMF) describe in the Journal of Molecular Liquids the development of a sensor that detects metronidazole in organisms and the environment. Metronidazole is an antibiotic used in human and veterinary medicine. Accumulation of this […]
Broadband buzz: Periodical cicadas’ chorus measured with fiber optic cables
From Entomological Society of America 11/12/23 Hung from a common utility pole, a fiber optic cable—the kind bringing high-speed internet to more and more American households—can be turned into a sensor to detect temperature changes, vibrations, and even sound, through an emerging technology called distributed fiber optic sensing. However, as NEC Labs America photonics researcher […]
Sweet Victory: Sensor detects adulteration in honey
From American Institute of Physics 22/10/23 Adulteration is a bitter truth in the sweet world of honey. As consumers seek nature’s nectar for its purity and health benefits, a shadowy industry taints this golden elixir with hidden additives, most commonly water. Standard detection methods of honey adulteration are expensive, and either have complicated operation methods […]
Itching for data: Sensor measures scratching intensity to help improve eczema treatments
From Carnegie Mellon University 20/09/23 Akhil Padmanabha knows about itching. His chronic itching caused by severe eczema was so debilitating that he was hospitalized twice and had to be home-schooled during most of his high school years. Itch so impacted his life that, as an undergraduate, he contemplated becoming a psychologist so he could help […]
Origami sensors could be wrapped around your organs to detect disease
From University of Southern California 28/08/23 Researchers at the USC Viterbi School of Engineering looked to origami to create new sensors that could someday be employed to detect deformations in organs and also for use in wearables and soft robotics. Their paper, “High-Stretchability and Low-Hysteresis Strain Sensors Using Origami-Inspired 3D Mesostructures,” featured in Science Advances […]
