Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional biomonitoring devices are limited in their ability to continuously and comprehensively monitor multiple analytes in the body, providing intermittent and detail-limited information, and are often designed for intermittent use, unable to effectively monitor body chemistry beyond a single analyte due to sensor limitations.
Innovation Solution
A new on-body microsensor system comprising an array of filaments with a substrate, conductive layer, insulating layer, sensing layer, and selective coating, configured to penetrate the skin for continuous or semi-continuous monitoring of multiple analytes, integrated with an electronics module for real-time data processing and analysis.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional biomonitoring devices are used, then device simplicity is maintained, but the ability to continuously monitor multiple analytes is limited
Solution Approach 1:
The device is segmented into multiple independent filaments, each equipped with specific sensors for detecting different analytes. This segmentation allows the system to monitor multiple analytes simultaneously while maintaining manageable complexity through modular architecture.
Solution Approach 2:
The filament array platform provides universal functionality by supporting multiple types of sensors on different filaments. Each filament can be configured with specific sensors for different analytes, allowing the same base structure to perform multiple monitoring functions.
2Loss of information
If intermittent monitoring is implemented, then device complexity is reduced, but information completeness is limited
Solution Approach 1:
The system enables continuous monitoring by maintaining constant contact between the filament sensors and interstitial fluid through skin penetration. This continuous action ensures uninterrupted data collection for comprehensive body chemistry information without requiring complex intermittent sampling mechanisms.
3Ease of manufacture
If single analyte monitoring is used, then manufacturing simplicity is maintained, but comprehensive health monitoring is limited
Solution Approach 1:
The manufacturing process is segmented into standardized steps for creating individual filaments with specific sensors. Each filament can be manufactured using similar processes, and then assembled into arrays, maintaining manufacturing ease while enabling multi-analyte capability through modular composition.
Solution Approach 2:
Different filaments are manufactured with locally optimized sensor configurations for specific analytes. This allows each filament to be tailored for its specific detection function while using standardized manufacturing processes, balancing ease of manufacture with specialized multi-analyte capabilities.
