Design of Powering Wireless Medical Sensor Based on Spiral-Spider Coils

Abstract

Biomedical sensors help patients monitor their health conditions and receive assistance anywhere and at any time. However, the limited battery capacity of medical devices limits their functionality. One advantageous method to tackle this limited-capacity issue is to employ the wireless power transfer (WPT) technique. In this paper, a WPT technique using a magnetic resonance coupling (MRC-WPT)-based wireless heart rate (WHR) monitoring system—which continuously records the heart rate of patients—has been designed, and its efficiency is confirmed through real-time implementation. The MRC-WPT involves three main units: the transmitter, receiver, and observing units. In this research, a new design of spiral-spider coil was designed and implemented for transmitter and receiver units, respectively, to supply the measurement unit, which includes a heart rate sensor, microcontroller, and wireless protocol (nRF24L01) with the operating voltage. The experimental results found that an adequate voltage of 5 V was achieved by the power component to operate the measurement unit at a 20 cm air gap between the receiver and transmitter coils. Further, the measurement accuracy of the WHR was 99.65% comparative to the benchmark (BM) instrument. Moreover, the measurements of the WHR were validated based on statistical analyses. The results of this study are superior to those of leading works in terms of measurement accuracy, power transfer, and Transfer efficiency.

“…For BMIs, WPT provides a safe, efficient, and comfortable charging approach that overcomes the complication of power capacity and decreases the cost and complications associated with surgical battery replacement. Several BMSs and BMIs are highly dependent on WPT, including left ventricular assist FIGURE 1 Classification of wireless power transfer technology devices (LVADs) [10], capsule endoscopes [11], heart rate sensors [12], deep brain stimulators (DBSs) [13], and many other biomedical applications.
