A new tool developed by nanoengineers at the University of California, San Diego, allows users, including physicians and patients, to easily build their own sensors.

Vanderbilt University researchers have created magnetically-driven laparoscopic instruments.

University of Washington researchers have created PolySTAT, a new injectable polymer that strengthens blood clots. The polymer, administered in a single shot, addresses internal injuries and reduces blood loss.

A new “smart bandage” from engineers at UC Berkeley uses electrical currents to detect early tissue damage from pressure ulcers, or bedsores, before they can be seen by human eyes. The device could potentially be carried by a nurse for spot-checking target areas on a patient, or incorporated into a wound...

A Rice University mobileVision system monitors eye health and spots signs of macular degeneration and diabetic retinopathy.The patient-operated, portable device can be paired with a smartphone to give clinicians finely detailed images of the macula – the spot in the center of the eye where vision is...

A University of Illinois research team developed a new method of soldering gaps in atomically small wires. The more flexible transistor technology, carbon nanotube wires, shows promise in replacing silicon devices.

New wireless retinal implants from Stanford University researchers convert light transmitted from special glasses into electrical current. The resulting current stimulates the retinal neurons known as bipolar cells.

Vienna University of Technology and Vienna Medical University researchers have created artificial blood vessels from a special elastomer material. To produce the vascular prostheses, polymer solutions were spun in an electrical field to form very fine threads and wound onto a spool. The prostheses can...

A portable Magnetic Resonance Imaging (MRI) device from the Los Alamos National Laboratory uses low-power magnetic fields to image the brain and other soft-tissue anatomy. The lightweight technology could be deployed on the battlefield and in the world's poorest regions.

Manufacturing researchers at the National Institute of Standards and Technology (NIST) have identified important challenges for powder bed fusion, the chief method for "printing" metal parts. By identifying the factors that influence the manufacturing process, professionals will improve the creation of...

A portable device, developed in part by EPFL researchers, monitors one's breath to quickly detect the presence of head and neck cancer. The technology, equipped with extremely sensitive sensors, has been tested on patients and operates with a computer or even a mobile phone.

Using a single laser pulse, a group of researchers at Delft University of Technology in The Netherlands has devised a method that allows silicon, in the polycrystalline form used in circuitry, to be produced directly on a paper substrate from liquid silicon ink. The process can be expanded to create...

A new potential manufacturing approach from Purdue University researchers harnesses inkjet printing to create devices made of liquid alloys. The resulting stretchable electronics are compatible with soft machines, such as robots that must squeeze through small spaces, or wearable electronics.

Using an inexpensive silicon chip less than a millimeter square in size, a nanophotonic coherent imager (NCI), developed by California Institute of Technology researchers, provides 3D maps with high depth-measurement accuracy.

A biosensing platform from Florida Atlantic University could be used to diagnose disease, remotely monitor patients, and determine treatment options for HIV, E-coli, Staphylococcus aureas, and other bacteria. Using a drop of blood from a fingerprick, the platform provides clinically relevant...

Royal Melbourne Institute of Technology (RMIT) University researchers have developed gas-sensing capsules that send data from inside the gut directly to a mobile device. To measure the concentration of selected intestinal gases, the capsule includes a built-in gas sensor, microprocessor, and wireless high-frequency...

Engineers at Oregon State University have used additive manufacturing to create an improved glucose sensor for Type 1 diabetes patients. Matched with portable infusion pumps, the new system monitors blood glucose concentrations, delivers insulin, and maintains safe hormone levels.

Using MRI, Johns Hopkins researchers developed a cancer detection method that does not rely on injected contrast dyes. The technique noninvasively finds telltale sugar molecules shed by the outer membranes of cancerous cells.

To address brain damage caused by explosions and neurotoxin exposure, researchers at the VA Boston Healthcare System are testing the effects of light therapy. Veterans in the study wear a helmet lined with light-emitting diodes that apply red and near-infrared light to the scalp. Diodes, placed in...
