Wearable sensors could revolutionize cancer radiotherapy safety

WOLLONGONG, AUSTRALIA: Researchers at the University of Wollongong (UOW) have unveiled a groundbreaking development in cancer treatment with wearable organic x-ray sensors. These innovative sensors are set to enhance safety and precision in radiotherapy, which is used by 50% of the 400 Australians diagnosed with cancer daily.
Led by Dr. Jessie Posar of UOW’s School of Physics, the study published in Advanced Functional Materials highlights the potential of organic semiconductors in monitoring radiation exposure during therapy. Unlike traditional silicon-based detectors, these sensors are lightweight, cost-effective, and biocompatible, making them ideal for wearable applications.
“These sensors can provide real-time radiation monitoring, ensuring better protection for healthy tissues while optimizing cancer cell targeting,” said Dr. Posar.
The technology was tested under clinical radiation beams and found to transmit 99.8% of the beam while accurately detecting radiation. The research also explored its application in advanced treatments like Microbeam Radiation Therapy, a modality aimed at untreatable tumors such as brain cancer.
Further collaboration with global experts and advancements in data science could accelerate the practical adoption of this technology, heralding a safer, more personalized era in oncology care.
