Squid ink might be a great ingredient to make black pasta, but it could also one day make getting checked for gum disease at the dentist less tedious and even painless. By combining squid ink with light and ultrasound, a team led by engineers at the University of California San...
New research has shown future wearable devices, such as smartwatches, could use ultrasound imaging to sense hand gestures. The research team is led by Professor Mike Fraser, Asier Marzo, and Jess McIntosh from the Bristol Interaction Group at the University of Bristol in the...
A new study by Osaka University scientists shows that non-labeling multiphoton microscopy (NL-MPM) can be used for quantitative imaging of cancer that is safe and requires no resection, fixation, or staining of tissues. It’s expected to simplify and reduce the time of cancer diagnosis.
Getting into the Halloween spirit, NASA released a collection of the spookiest sounds ever recorded by the agency's spacecraft instruments. Captured radio emissions reveal whistling helium, howling planets, and other mysterious noises from the depths of space.
A technique known as Selected Ion Flow Tube Mass Spectrometry (SIFT-MS) instantly analyzes air down to part-per-trillion (ppt) concentrations. The SIFT-MS technology can be used to test vehicles for emissions and volatile organic compounds, including irritants, toxins,...
A novel, pencil-sized device now provides surgeons with an alternative to traditional methods of suturing arteries. The Arterial Everter, Medical Category winner of the 2017 “Create the Future” Design Contest, will reduce operation times, according to the technology’s inventor.
To reduce costs and eliminate air pollution, many cities are exploring the benefits of electric buses. Before electrified fleets take the road, however, officials will require a test run. The National Research Council of Canada (NRC) used a modeling approach.
Petrochemical and liquid gas companies require a regular inspection of a vessel's welds and wall thicknesses — a dangerous task given the hazardous environment. A climbing robot, category winner in the 2017 “Create the Future” Design Contest, is potentially up to the challenge.
Conformal coatings like Parylene protect a variety of components, including LEDs, sensors, and circuit card assemblies. If a board component needs to be replaced, however, how easily can the Parylene be removed?
Who needs a keyboard, a mouse, or a joystick? A researcher from Arizona State University wants to command machines with the human brain.
Many structural factors contribute to automotive noise, whether the vehicle is electric or has an internal combustion engine. In a webinar this week titled, “The Art of NVH Attenuation,” an attendee asked Dr. Pranab Saha, a consultant and expert in acoustics, noise, and vibration...
Digital Image Correlation (DIC) is a non-contact optical method of measuring deformation and strain on a given material. Measurement accuracy, however, depends on contrast, illumination, and light intensity.
The editors of September’s Sensor Technology magazine compiled a list of top sensor vendors, organized by product type. Explore this year’s OEM Sensors Supplier Guide.
Today's vehicles feature traditional internal combustion engines, hybrid, plugin, and electric drivetrains. A reader asks: "Which power-plant choice will take the lead in 2020?"
Looking for new cameras, lasers, or optics? Our 2017 OEM Photonics & Imaging Directory, featured in the September issue of Tech Briefs, reviews essential vendors.
Despite the growing use of wireless radio frequency ID (RFID) tags, lost inventory still costs warehouses billions of dollars every year. Researchers from the Massachusetts Institute of Technology (MIT) have developed an aerial way of supplementing the RFID technology: small, safe drones.
Modern avionics are highly dependent on reliable connectivity — and reliable interconnection systems. As data rates inevitably improve to address greater military requirements, how will the increase impact signal integrity?
