Current hearing-loss treatments deliver drugs to the middle ear by requiring repeat injections. A device from The Charles Stark Draper Laboratory, Cambridge, MA, sends precise, automated, and timed quantities of one or more drugs directly into the fluid of the inner ear.

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.
