Context-aware electromagnetic design for continuously wearable biosymbiotic devices

Imperceptible wireless wearable devices are critical to advance digital medicine with the goal to capture clinicalgrade biosignals continuously. Design of these systems is complex because of unique interdependent electromagnetic, mechanic and system level considerations that directly influence performance. Typically, approaches consider body location, related mechanical loads, and desired sensing capabilities, however, design for real world application context is not formulated. Wireless power casting eliminates user interaction and the need to recharge batteries, however, implementation is challenging because the use case influences performance. To facilitate a data-driven approach to design, we demonstrate a method for personalized, context-aware antenna, rectifier and wireless electronics design that considers human behavioral patterns and physiology to optimize electromagnetic and mechanical features for best performance across an average day of the target user group. Implementation of these methods result in devices that enable continuous recording of high-fidelity biosignals over weeks without the need for human interaction.

Automated summary

We demonstrate a personalized, context-aware method for designing antennas, rectifiers, and wireless electronics that optimize electromagnetic and mechanical features based on human behavioral patterns and physiology. By implementing these methods, we can achieve continuous recording of high-fidelity biosignals for weeks without the need for human interaction.
