Using patent-pending technology called Coded Hemodynamic Imaging, University of Waterloo researchers can monitor vital signs and improve the detection and prevention of cardiovascular conditions. The touchless, portable system monitors a patient's blood flow at multiple arterial points...

Researchers from North Carolina State University, Raleigh, and Duke University have developed a metamaterial made of paper and aluminum that can manipulate acoustic waves to more than double the resolution of acoustic imaging, focus acoustic waves, and control the angles at which sound passes...

University of Michigan researchers have built and tested neural probes that hold what are believed to be the smallest implantable LEDs ever made. The new probes control and record the activity of many individual neurons, measuring how changes in the activity of a single neuron can affect its neighbors. The...

Columbia University Engineering Department researchers have, for the first time, harnessed living systems to power an integrated circuit using adenosine triphosphate (ATP), the energy currency of life. The team integrated a conventional solid-state complementary metal-oxide-semiconductor (CMOS)...

A University of Illinois at Urbana-Champaign engineer and an ophthalmologist have developed a portable sensor that quickly and inexpensively determines whether an eye injury is mild or severe. The device, called OcuCheck, could speed efforts to determine the extent of eye injuries at accident sites,...

A new sensor developed by Duke University and Stanford University researchers provides a real-time, eagle-eye view of neural activity in mammalian brains. The technique watches the brain’s neurons with a temporal resolution of about 0.2 milliseconds.

Researchers in the Cockrell School of Engineering at The University of Texas at Austin have developed a self-healing gel that repairs and connects electronic circuits, creating opportunities to advance the creation of flexible electronics, biosensors, and batteries.

By using plasmons to “wiggle” a free electron in a sheet of graphene, researchers at the Massachusetts Institute of Technology (MIT) have developed a new method for generating X-rays. The discovered phenomenon could lead to more compact, tunable X-ray devices made of graphene.

The ability to integrate disparate materials and properties within printed objects is the next frontier in 3D printing. Harvard University researchers have designed new multimaterial printheads that mix and print concentrated viscoelastic inks, enabling simultaneous control of composition...

Researchers at The University of Alabama created a material that manipulates and reduces the speed of light in a new, more effective way. The resulting "slow light" will lead to the development of optical buffers and delay lines used in next-generation sensors.

Engineers at the University of Texas at Arlington Research Institute (Fort Worth, TX) and The University of Washington (Seattle, WA) have developed a healing glove that delivers needed medicine to an injured hand. The device, known as the Bioengineered Smart-Glove for Regenerative Healing...

A noninvasive device developed by Texas A&M University researchers enables doctors to quickly and accurately identify cancerous tissue in a person’s mouth. Fluorescence Lifetime Imaging (FLIM) measures and visualizes the biochemical changes that occur in oral epithelial tissue as it turns...

Current lithium-ion batteries normally use graphite anodes. University of Waterloo researchers have created lighter, long-lasting batteries from silicon. The silicon anode materials have a much higher capacity for lithium and are capable of producing batteries with almost 10 times more energy.

IEEE, Piscataway, NJ, has announced a new standard and two new standards development projects designed to support plug-and-play, interoperable communications across eHealth devices. The new eHealth standard is IEEE 2410™-2015, Biometrics Open Protocol Standard,...

Wearable devices developed by researchers at UMass Medical School non-invasively monitor patients with serious cardiac disease. A vest detects sub-clinical cardiac dysfunction, and a smartwatch finds life-threatening rhythm abnormalities.

A hyperspectral camera built by researchers at the University of Washington uses both visible and invisible near-infrared light to “see” beneath surfaces and capture unseen details. The HyperCam captures detailed images of vein and skin texture patterns that are unique to an individual.

Computer scientists and a professor of ophthalmology at the University of Utah have developed software that maps out a monkey’s brain. By gaining an accurate 3D model of the brain’s network of neurons, medical researchers can better understand how the brain’s connectivity is disrupted in mental and...

Engineers at the University of California, San Diego, have developed a mouth guard that monitors health markers, such as lactate, cortisol, and uric acid, in saliva. The information can then be wirelessly transmitted to a smartphone, laptop, or tablet.

A stimulated Raman scattering (SRS) microscope currently being tested at the University of Michigan allows surgeons to quickly spot the difference between tumor tissue and normal brain tissue. Since June, the SRS microscope has imaged more than 60 patient samples from the operating room.

Researchers at the University of Montreal Hospital Research Centre (CRCHUM) have developed virtual models that can be used in angiography rooms to address aortic aneurysms and help medical professionals visualize the area being treated. To provide more personalized treatments, the new software...

Researchers in the Cockrell School of Engineering at The University of Texas at Austin produced inexpensive wearable patches that continuously monitor the body’s vital signs. Their repeatable, “cut-and-paste” method cuts manufacturing time from several days to only 20 minutes.

A strong, lightweight metal foam created by a North Carolina State University researcher absorbs the energy of high-impact collisions and effectively blocks X-rays, gamma rays, and neutron radiation. The device offers new shielding possibilities for use in CT scanners.
