 Abstract surgery is a type of primary clinical treatment for solid tumors. It involves frequent hospital visits due to the high risk of local relapse. To address this issue, researchers have developed a stretchable electronic device that can be worn as a patch and used to deliver targeted treatments such as chemo and thermotherapy. This device uses compliant materials to attach securely to the surgical site, and it is equipped with a nanotextile dressing that releases drugs when activated by electrical or thermal stimulation. Additionally, a flexible circuit and a compact battery provide power to the device, allowing it to operate remotely via a smartphone. In tests, the device successfully delivered both chemo and thermotherapy to inhibit tumor growth, demonstrating its potential use in wearable therapies.
