Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing health monitoring systems for soldiers in dynamic environments, such as warzones, face challenges in accurately and reliably detecting electromagnetic field (EMF) signals from the human body due to issues with contact-based electrodes, which are cumbersome, prone to signal degradation, and unsuitable for fast-changing environments, and non-contact methods struggle with signal detection and localization.
Innovation Solution
A hybrid EMF detection system using wearable antennas that can detect both contact and non-contact EMF signals, incorporating biopotential amplifiers with high input impedance and differential design to minimize noise, and active harmonic signal calibration to enhance signal processing, allowing for non-intrusive monitoring of bioelectrical signals across a wide frequency range.

Engineering Contradiction Analysis
1Measurement precision
If contact-based electrodes are used to detect EMF signals, then signal detection capability is improved, but device complexity and ease of operation deteriorate due to cumbersome setup and signal degradation
Solution Approach 1:
The patent replaces contact-based mechanical electrodes with non-contact antenna-based EMF detection. The antenna system detects electromagnetic fields emitted by the body without physical contact, eliminating the need for skin preparation, gel application, and secure attachment procedures associated with traditional electrodes. This substitution maintains signal detection capability while dramatically simplifying device operation and reducing setup complexity.

This substitution maintains signal detection capability while dramatically simplifying device operation and reducing setup complexity.
3Ease of operation
If non-contact methods are used to detect EMF signals, then ease of operation is improved, but measurement precision deteriorates due to signal detection and localization difficulties
Solution Approach 1:
The patent divides the detection system into multiple antenna elements arranged in an array. Each antenna element detects EMF signals from specific spatial zones, enabling the system to segment the detection task across multiple sensors. This segmentation allows for better signal localization and precision while maintaining the ease of non-contact operation, as the array configuration provides spatial information that single-antenna systems lack.
Solution Approach 2:
The patent combines signals from multiple antenna elements through signal processing techniques. By merging the detection capabilities of multiple antennas, the system achieves improved measurement precision and localization accuracy while maintaining the operational simplicity of non-contact detection. The combined signal processing approach extracts meaningful physiological information that would be difficult to obtain from a single antenna.
