(Press-News.org) Researchers from RMIT University have developed a wearable wound monitoring device with integrated sensors that could reduce infection risks by minimising the need for frequent physical contact.
Standard methods require regular removal of wound dressings for assessments, often delaying crucial interventions, whereas this invention monitors healing remotely via a Bluetooth connection.
The proof-of-concept device is designed for reuse, making it more cost-effective and practical than disposable smart bandages and other emerging wound monitoring technologies.
Globally, millions of people suffer from chronic wounds, impacting their quality of life and incurring significant healthcare costs. In Australia, about 500,000 people are affected, costing the healthcare system $3 billion annually.
Lead inventor Dr Peter Francis Mathew Elango said the device used advanced integrated sensor technology – including inflammation, pH and temperature sensors – to continuously track key healing indicators. High temperatures signal inflammation or infection, while changes in pH levels can indicate different stages of wound healing.
“We tested our wound monitoring device by simulating conditions it would encounter in wound management. We placed the device on a human arm to demonstrate that it conforms well to the curved surface,” said Elango, from the School of Engineering.
“This was a test to show that this type of alternative monitoring technology is possible, and we are now ready to work with industry partners to develop it for clinical trials.
“Its components are biocompatible and fit seamlessly into existing manufacturing workflows and processes, potentially bringing the cost below $5 per unit when produced at scale.”
An RMIT-patented technology platform underpins this innovation, with flexible sensors that can be placed on or next to a wound under dressings.
“The high-resistivity silicon-based sensor technology is our platform IP that has been proven to be efficient at multiple biomarker detection related to different ailments,” said team leader Professor Madhu Bhaskaran.
Bhaskaran’s Functional Materials and Microsystems Research Group at RMIT has a strong track record developing med-tech devices, including bedding sensors for use in aged care to monitor sleep quality and comfort. Meanwhile, earlier work led by Elango on a wearable heart monitor is now progressing towards commercialisation through a partnership with Perth-based Lubdub Technologies.
Their latest journal article, ‘Multiplexed cutaneous wound monitor for point-of-care applications’, is published in Advanced NanoBiomed Research (DOI: 10.1002/anbr.202500142).

Study reveals spinning could reduce NHS waiting lists for physiotherapy treatments
2025-07-31
A new study by Bournemouth University (BU) and University Hospitals Dorset (UHD) has revealed the benefits of spinning for patients with hip osteoarthritis. The study was funded by the National Institute for Health Research (NIHR) and will be published in Lancet Rheumatology at 23:30 UK time on Thursday 31st July 2025.
Participants within the study who took part in the weekly cycling and education sessions reported better recovery outcomes compared to participants who undertook regular physiotherapy. The results reveal that better outcomes for patients can be achieved in a group setting using the cycling and ...
New AI tool illuminates “dark side” of the human genome
2025-07-31
LA JOLLA (July 31, 2025)—Proteins sustain life as we know it, serving many important structural and functional roles throughout the body. But these large molecules have cast a long shadow over a smaller subclass of proteins called microproteins. Microproteins have been lost in the 99% of DNA disregarded as “noncoding”—hiding in vast, dark stretches of unexplored genetic code. But despite being small and elusive, their impact may be just as big as larger proteins.
Salk Institute scientists are now exploring the mysterious dark side of the genome in search of microproteins. With their new tool ShortStop, researchers ...
CCNY team discovers potential chemo-induced cognitive changes in cancer survivors
2025-07-31
Researchers at The City College of New York have linked chemotherapy treatment to lasting cognitive changes in rats – potentially shading light, for the first time, on cognitive problems some cancer survivors experience long after treatment ends. Entitled “Chemotherapy treatment alters DNA methylation patterns in the prefrontal cortex of female rat brain,” the study appears in the journal Nature: Scientific Reports.
“Our study explored how chemotherapy affects the brain at the molecular level using an animal ...
New mRNA-based therapy that shows promise in heart regeneration after heart attack
2025-07-31
Heart attacks remain a leading cause of death and disability worldwide. The permanent loss of heart muscle cells—known as cardiomyocytes—and the heart’s limited regenerative capacity often led to chronic heart failure. Current treatment strategies manage symptoms but do not repair the underlying damage. Now, researchers at the Lewis Katz School of Medicine at Temple University have identified a new strategy that may help repair damaged heart tissue by reactivating an important developmental gene.
In a study published in Theranostics, a multidisciplinary team led by Raj Kishore, PhD, Laura H. Carnell Professor, Vera J. Goodfriend ...
Extremists use gaming platforms to recruit - study
2025-07-31
New research published in the journal Frontiers in Psychology reveals how extremist groups are exploiting the popularity of video games to recruit and radicalise impressionable users.
The study shows that gaming-adjacent platforms, which allow users to chat and live stream while playing, are being used as “digital playgrounds” for extremist activity and that video game players are being deliberately “funnelled” by extremists from mainstream social media platforms to these sites, in part ...
Nearly 70% of U.S. children in car crashes with a fatality were not using proper child passenger restraints, study finds
2025-07-31
Despite national guidelines, state laws and known safety benefits of child passenger restraint systems (CRS), suboptimal practices were found in nearly 70% of children under 13 years old who were involved in car crashes with a fatality from 2011 to 2021, according to a study published in the journal Traffic Injury Prevention.
“Given the continued problem of suboptimal child passenger safety practices among children across the country, there is a need for innovative, targeted programs to promote correct and consistent use of age-appropriate car seats, ...
Understanding what makes some bladder cancers resistant to chemotherapy
2025-07-31
About one quarter of patients with muscle-invasive bladder cancer (MIBC) may be treated and derive a benefit with the current standard chemotherapy. To better understand why some tumors resist chemotherapy and identify better ways to treat those cancers, researchers at Baylor College of Medicine have conducted a detailed molecular analysis of MIBC tumors. The results, published in Cell Reports Medicine, offer potential new ways to identify which patients will benefit from chemotherapy and reveal possible new treatment strategies.
“One of our goals was to identify molecular markers in patient tumors that would help us predict which patients were ...
Protecting your beating heart
2025-07-31
You may have heard the phrase “my heart skipped a beat” when someone was talking about a romantic encounter. In truth, hearts that beat irregularly are dangerous for your health. Atrial fibrillation (AF) is the most common type of irregular heartbeat, and over time, it can worsen and become a permanent condition, a severe disorder that’s the leading preventable cause of ischemic stroke, according to the NIH. Nicolae Moise, a research scientist in the Department of Biomedical Engineering at Ohio State University ...

Saliva testing may reveal early signs of diabetes and obesity
2025-07-31
Measuring elevated levels of insulin in blood, called hyperinsulinemia, is a proven way to measure metabolic health and can show risk of developing future health concerns, including Type 2 diabetes, obesity and heart disease.
Now, a team of UBC Okanagan researchers has found that measuring insulin levels in saliva offers a non-invasive way to do the same test—without the need for needles or lab-based blood work.
Dr. Jonathan Little, Professor with UBC Okanagan’s School of Health and Exercise Sciences, says that a simple spit ...
