Artificial eyes could bring human-like sight to self-driving cars, robots

Although self-driving cars and sophisticated robots use advanced cameras, computer algorithms and artificial intelligence (AI) to picture their surroundings, these artificial eyes struggle to remain reliable in mixed lighting conditions. A team of researchers, co-led by an engineer from Penn State, has proposed a solution that mimics the mechanics of the human eye to adapt from bright to dark light in seconds.

Materials lab in national program to develop wearable eye health system

The Advanced Research Projects Agency for Health (ARPA-H), an agency within the U.S. Department of Health and Human Services (HHS), has awarded up to $75.8 million to four research teams through its Ocular Laboratory for Analysis of Biomarkers (OCULAB) program. Researchers from Penn State will develop biosensors for the Closed-Loop Sensing and Microdosing for Dry Eye and Systemic Disease Management (COSMIC) team led by Lacristat, a California-based ophthalmology company.

Novel biogel may solve a hairy problem for wearable brain-monitoring systems

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. Researchers at Penn State have developed a reusable material designed to solve both problems at once. The material is a thermoreversible semiconducting ionic biogel, meaning it becomes liquid when gently heated so it can move through hair and reach the scalp, then returns to a stable gel as it cools, keeping its conducting and semiconducting character.

Stretchy implants could stick to arteries to treat high blood pressure

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.

3D-printed brain sensors may unlock personalized neural monitoring

Soft electrodes designed to perfectly match a person’s brain surface may help advance neural interfaces for neurodegenerative disease monitoring and treatment, according to a new study led by Penn State researchers. Neural interfaces are powered by tiny sensors capable of tracking biophysical signals, known as bioelectrodes.

Medina, Paris receive 2026 Excellence in Advising Award

Scott Medina, the William and Wendy Korb Early Career Professor and Dorothy and J. Lloyd Huck Chair in Nano Bioengineering; and Heather Paris, associate director of the advising center and career services at Penn State Wilkes-Barre, have been selected to receive the 2026 Penn State Excellence in Advising Award.

WATCH: Cell ‘snowball’ may be answer to large-scale tissue engineering

Cell cultures — single layers of cells grown in a small dish — have enabled researchers to study biological growth, develop or test drugs and even discover what causes some diseases. Cell spheroids, 3D versions of cell cultures built using a process known as cell aggregation, are the next step in advancing this work, capable of more closely modeling real tissue.

Q&A: Robots can’t feel; these sensors could change that

A research team, including Huanyu “Larry” Cheng, James L. Henderson Jr. Memorial Associate Professor of Engineering Science and Mechanics at Penn State, is using pressure sensors — tiny devices, roughly the size of a paperclip, that can measure the force applied over an area — to design a highly sensitive electronic “skin” to use alongside robots and prosthetic limbs.

Q&A: Gassing up bioengineered materials for wound healing

Biomaterials are specifically engineered to support tissue, nerve and muscle regeneration across the body, yet physicians and researchers have limited control over the size and connectivity of the internal pores that transfer oxygen and vital nutrients to where they are most needed. To solve this problem and better support tissue regeneration, a team at Penn State has designed a new class of tunable biomaterials.
