Transforming brain monitoring with bioresorbable wireless sensing

The ability to continuously and accurately monitor intracranial physiological indices is crucial for the diagnosis and management of various neurological conditions, including traumatic brain injury, hydrocephalus, and cerebrovascular disorders. However, conventional approaches involving wired instruments with percutaneous leads are fraught with challenges, including the risk of infection, restriction on patient movements, and potential surgical complications during insertion and removal. In a recent study, an interdisciplinary team led by Professors Jianfeng Zang, Xiaodong Chen and Xiaobing Jiang proposed an innovative solution—an injectable, bioresorbable, and wireless sensor for ultrasonic monitoring of intracranial signals.
