Wireless Cerebral Blood Flow Monitoring System Based on Inductance Sensing Technology

Ischemic stroke is one of the important causes of neurological morbidity and mortality. After ischemic stroke occurs, blood perfusion is decreased. Timely restoration of blood flow to ischemic brain tissue is the key to treatment. In this paper, a wireless cerebral blood flow (CBF) monitoring system based on inductive sensing technology is proposed, which collects CBF data through CBF sensor and LDC1612 EVM module. The STM32F103C8T6 microcontroller and ATK-ESP8266WiFi module wirelessly transmits CBF data to the host computer for real-time display. Physical experiment was designed to explore the monitoring range and depth of the system, analyze the amplitude information of the periodic beat signal. To verify the feasibility of the wireless CBF monitoring system based on inductive sensing technology to monitor CBF. The results of physical experiments show that the system introduced in this paper can monitor the pulse signal of CBF at medium depth. The wireless CBF monitoring system based on inductive sensing technology has been preliminarily verified to be able to monitor the pulse signal of CBF. Interference caused by wired is avoided. It is expected to achieve real-time continuous monitoring of CBF in patients with ischemic stroke, assisting diagnosis and treatment.
