Moisture-Responsive Film for Objective Hyperhidrosis Diagnosis
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing diagnostic methods for hyperhidrosis, such as the starch/iodine test, are burdensome, time-consuming, and subjective, leading to inaccurate and potentially embarrassing results for patients.
Innovation Solution
A moisture-responsive film (MRF) that forms a visualizable complex with iodine and water upon skin contact, providing a quantitative and reproducible assessment of sweat production without skin staining, using a complexing substrate with a thin iodine layer.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the starch/iodine test is used for diagnosing hyperhidrosis, then diagnostic capability is provided, but the process becomes burdensome and time-consuming
Solution Approach 1:
The patent transforms the diagnostic approach by changing the physical state of the reagent from a multi-component starch/iodine solution requiring manual application to a pre-coated film with controlled moisture sensitivity. The film's parameters (thickness, coating composition, moisture content) are optimized to enable rapid color change upon contact with sweat, reducing diagnosis time while maintaining reliability
Solution Approach 2:
The iodine and starch components are pre-applied and integrated into the film structure before use. This preliminary preparation eliminates the need for manual application of separate reagents during the diagnostic process, allowing immediate detection upon skin contact and significantly reducing the time required for diagnosis
2Reliability
If the starch/iodine test is used for diagnosing hyperhidrosis, then diagnostic capability is provided, but the results become subjective and inaccurate
Solution Approach 1:
The film incorporates localized calibration regions with known moisture characteristics alongside the diagnostic test area. These calibration zones provide reference points for objective comparison, enabling precise quantification of sweat production and eliminating subjective interpretation. The local quality variation between test and calibration regions enhances measurement precision
3Reliability
If the starch/iodine test is used for diagnosing hyperhidrosis, then diagnostic capability is provided, but skin staining and patient discomfort occur
Solution Approach 1:
The patent extracts the iodine staining function from the diagnostic process by using a film that contains the reagent in a controlled, pre-measured form. The film's structure allows the iodine to react with sweat only in the controlled test area, and the reaction products remain confined to the film rather than staining the skin. This separation of the reagent application from direct skin contact eliminates the harmful staining effect while preserving diagnostic capability

AI summary
A moisture-responsive film can include a complexing substrate and an iodine layer applied to the complexing substrate to form the moisture-responsive film. The moisture-responsive film can include a test area formed on a testing surface of the moisture-responsive film. The moisture-responsive film may be used to diagnosis hyperhidrosis and or sweating or moisture-related conditions on a variety of skin surfaces.
