Researchers have developed an innovative wearable patch capable of detecting early signs of the deadliest form of skin cancer. This wireless device enables individuals to conduct self-screening at home, potentially identifying melanoma sooner and reducing the need for unnecessary biopsies. The creation of the battery-free patch aims to make screening more convenient and less intrusive, emphasizing the severity of skin cancer, particularly melanoma, as one of the most hazardous types of the disease.
Melanoma UK estimates that over 19,000 individuals in the UK will receive a melanoma diagnosis by 2025. Early detection plays a vital role in successful treatment, yet existing methods heavily rely on visual inspection, which can be subjective and may miss crucial early warning signs.
The patch, designed by a team at Wake Forest University School of Medicine in North Carolina, measures the bioimpedance of skin lesions in a simple and non-invasive manner. By assessing the electrical properties of skin, the patch can identify abnormal areas that may necessitate further medical attention. The device, which does not require batteries or chips, is lightweight, disposable, and cost-effective, providing objective data on skin health to reduce unnecessary biopsies and aid healthcare professionals in making informed decisions.
Through safe electrical signals, the patch can differentiate between healthy and abnormal skin, offering additional information on lesions and supporting other diagnostic techniques. The research team plans to enhance the patch by incorporating conductive hydrogel electrodes for improved performance and comfort. Further clinical studies will be conducted to evaluate the patch’s effectiveness in real-world scenarios and its ability to distinguish between benign and malignant lesions accurately.
Dr. Mohammad Moghimi, the project leader, envisions the patch as a tool accessible to everyone, aiming to enhance early skin cancer detection and improve patient outcomes by reducing missed or delayed diagnoses.
