Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current biomonitoring devices provide limited, intermittent, and burdensome monitoring of body chemistry, often requiring invasive procedures like finger sticks and are limited to analyzing a single or few analytes due to sensor limitations.
Innovation Solution
A system comprising a microsensor patch with an array of filaments that penetrates the skin to sense multiple analytes continuously, integrated with an electronics subsystem for signal processing and transmission, allowing for continuous monitoring of body chemistry without invasive procedures.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If current biomonitoring devices are used, then they can determine analyte levels and provide information to users, but the information is limited in detail, intermittent, and requires invasive procedures like finger sticks
Solution Approach 1:
The patent replaces mechanical invasive procedures (finger sticks, lancing) with a non-invasive optical sensing system that uses light interaction with tissue to detect analyte levels, eliminating the need for physical penetration of the skin
Solution Approach 2:
The system is designed to monitor multiple analytes simultaneously (glucose, lactate, ketones, etc.) using a single device platform, transforming single-purpose blood glucose meters into multi-functional biomonitoring systems
2Measurement precision
If current biomonitoring devices are used, then they can provide analyte level information, but the monitoring is intermittent and user-prompted rather than continuous
Solution Approach 1:
The system enables continuous real-time monitoring of analyte levels through persistent optical sensing, eliminating the intermittent nature of traditional devices that require manual user initiation for each measurement
3Adaptability or versatility
If current biomonitoring devices are used, then they can analyze analytes, but they are limited to one or a limited number of analytes due to sensor limitations
Solution Approach 1:
The patent implements a multi-analyte sensing platform that can simultaneously detect multiple different analytes (glucose, lactate, ketones, electrolytes, etc.) using integrated optical sensors, expanding the device's versatility beyond single-analyte monitoring
Solution Approach 2:
The system combines multiple sensing capabilities into a single integrated device, merging the functions of what would traditionally require separate devices or tests into one unified biomonitoring system
