Researchers at the University of São Paulo (USP) in Brazil have developed a kraft paper-based electrochemical sensor that can detect traces of pesticides in fruit and vegetables in real time when coupled to an electronic ...
Have a cough, sore throat and congestion? Any number of respiratory viruses could be responsible. Conventional tests can identify certain likely culprits by relying on chemical reactions, but some researchers want to swap ...
World-first 'phase change inks' that could transform how we heat and cool buildings, homes and cars—to achieve sophisticated 'passive climate' control—have been developed, with enormous potential to help reduce energy ...
Researchers in the Oregon State University College of Engineering have developed a handheld sensor that tests perspiration for cortisol and provides results in eight minutes, a key advance in monitoring a hormone whose levels ...
Chip-scale miniaturization of spectrometers allows rapid detection of spectral information in portable devices, opening up new applications. However, integrated spectrometers typically suffer from a trade-off between spectral ...
Science and design researchers at QUT have joined forces to develop reusable, color-changing prototypes of jewelry and accessories that use new switchable dye technology to warn people when they've had too much sun.
According to the data of the World Health Organization, about 430 million people worldwide suffer from hearing loss due to cochlear damage, and the improvement of hearing mainly depends on cochlear implants. However, traditional ...
Carbon nanotubes (CNTs) are cylindrical tube-like structures made of carbon atoms that display highly desirable physical properties like high strength, low weight, and excellent thermal and electrical conductivities. This ...
Sweat contains biomarkers that help doctors make health diagnoses. Wearable sensors can be used to monitor a person's perspiration rate and provide information about the skin, nervous system activity and underlying health ...
Scientists at the University of Massachusetts Amherst recently announced the invention of a nanowire, 10,000 times thinner than a human hair, which can be cheaply grown by common bacteria and can be tuned to "smell" a vast ...
