Wearable health monitors are designed to move with the body. But for many devices, movement creates a problem: The more a person bends, stretches, reaches or runs, the harder it can be for the device to keep a stable wireless connection. Penn State researchers and international collaborators set out to solve that problem by developing a soft, stretchable antenna that can keep working even when pulled in different directions.

UNIVERSITY PARK, Pa. — A vital tool for healthcare practitioners, electroencephalography (EEG) systems measure electrical activity in the brain through electrodes placed on the scalp, but getting reliable readings can be surprisingly difficult. Hair interferes with contact between the electrodes and skin, and the gels used to improve those connections often dry out over time, weakening signal quality.

High blood pressure, formally known as hypertension, is a leading cause of heart disease in the United States, impacting nearly half of all adults. Approximately one in 10 of these patients experience drug-resistant hypertension that can be difficult to address, but according to researchers at Penn State, tiny devices that gently shock one of the body's most critical arteries could offer effective treatment.

To investigate the interactions between the influenza virus and bacterial microbe infections and how these interactions impact the lungs, a team co-led by researchers at Penn State and Duke University School of Medicine has been awarded a four-year, $3.2 million grant from the National Institutes of Health.

When patients undergo reconstructive surgery for devastating injuries, one of the biggest obstacles surgeons face is restoring blood supply to the repaired tissue. Without a functioning vascular system, new grafts cannot survive. With a new $3 million grant from the National Institutes of Health, researchers at Penn State are taking on this challenge by combining advanced 3D bioprinting with a novel surgical method, known as micropuncture.

Collaborating with orthopedic surgeons, a team led by biomedical engineering researchers at Penn State created CitraBoneQMg, an implantable biodegradable scaffold to support bone regrowth made by combining magnesium and glutamine with citric acid. They published research on their implant, for which they filed a U.S. patent application, in Science Advances.
