Project Title: Passive Wireless Flow Sensing for Hydrocephalus Valves

The proposed monitoring system is designed to improve the care of patients with hydrocephalus who rely on shunt systems to regulate cerebrospinal fluid (CSF) by enabling accurate, long-term assessment of shunt function without necessitating medical imaging or surgery. Its fully passive and chipless design, without surface-mounted components, implanted active electronics, wired connections, or onboard power, reduces complexity and may lower risks associated with powered or active implants. The bias line can be manufactured at variable lengths, allowing compatibility with both pediatric and adult patients and flexible placement within a standard shunt system. The proposed system has the potential to reduce diagnostic uncertainty, minimize unnecessary exploratory surgeries, and support more timely and informed clinical decision-making, thereby leading to substantial improvements in patient care.
