Background:

• Hydrocephalus involves abnormal cerebrospinal fluid (CSF) accumulation in brain ventricles.
• Current CSF diversion shunts face complications like infection, obstruction, and over-drainage.
• Shunt malfunctions can necessitate emergency interventions, impacting patient health.

Purpose of the Study:

• To introduce a novel soft, wireless device for monitoring distal shunt fluid flow.
• To enable precision measurement of CSF flow rate over extended periods.
• To provide early detection of shunt malfunctions and potential complications.

Main Methods:

• Development of a multimodal sensing device with flow sensors and electrodes.
• Integration of a fluidic chamber for precise flow rate and resistance measurements.
• Implementation of low-power Bluetooth for smartphone data transmission.

Main Results:

• The device enables precision measurement of CSF flow rate under various conditions.
• It allows for long-term monitoring of fluid dynamics within shunt systems.
• The wireless, smartphone-connected design facilitates remote data access.

Conclusions:

• The developed device offers a promising solution for monitoring hydrocephalus shunt function.
• Its universal design aims for compatibility with existing commercial shunt systems.
• This technology has the potential to enhance patient care and reduce shunt-related complications.
