Low-cost, screen-printed carbon sensors have been used to rapidly detect bacteria commonly found in wounds, which could pave the way for a real time medical device.
A study carried out by the University of Strathclyde and NHS Ayrshire & Arran used sensitive portable electrochemical sensors, which detected infections in clinical samples within half an hour, much quicker than current hospital laboratory testing.
The detection of infection in clinical practice can be expensive and … read more
Wound healing is a delicate tissue regeneration procedure that entails numerous changes in various physiological parameters.
FREMONT, CA: Wearable sensors and systems refer to devices that can detect minute amounts of biological or chemical analytes and convert chemical reactions or physical changes into usable signals (optical or electrical signals, for example) following predefined rules. Wearable sensors/systems for monitoring markers in or around the wound environment can provide real-time symptom information and hold promise for therapy studies, which also meets the World Union of Wound Healing Societies’ requirement that “diagnostic tools be moved into the clinic or patient’s home to ensure optimal care is provided for patients with wounds.” Researchers have developed various wearable sensors/systems based on optical (fluorescence, colorimetry, etc.) or electrical (impedance, potentiometry, amperometry, etc.) mechanisms integrated with conventional wound dressings to form innovative wound dressings. These smart wound dressings convert changes in these biomarkers into visual or electrical signals, allowing for real-time monitoring of wound healing … read more
