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.

A new skin-like sensor developed by an international team led by researchers at Penn State could help doctors monitor vital signs more accurately, track healing after surgery and even help patients with bladder control issues. 

The sensor, which can be worn on the skin or implanted inside the body, can measure both physical movement and electrical signals. It is made from soft, stretchable materials that mimic human skin and is designed to work for long periods of time without losing performance.

Saying one thing while feeling another is part of being human, but bottling up emotions can have serious psychological consequences like anxiety or panic attacks. To help health care providers tell the difference, a team led by scientists at Penn State has created a stretchable, rechargeable sticker that can detect real emotions — by measuring things like skin temperature and heart rate — even when users put on a brave face.
