Transdermal Patch Battery Isolation Segmentation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing biological tissue transdermal patches face issues with self-discharging and corrosion due to continuous contact between active ingredients and electrodes, requiring gel forms and complex application procedures, and often use harmful materials in power supplies, increasing environmental concerns.
Innovation Solution
A biological tissue transdermal patch design that isolates a battery part and active ingredient within a plastic pack, allowing them to be stored separately and brought into contact only during use, utilizing a magnesium-air battery reaction without electrolytes, allowing the active ingredient to function as an electrolyte and reducing environmental impact.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the active ingredient is kept in contact with the battery part during storage, then the battery reaction can start immediately upon application, but self-discharging and corrosion occur during storage
Solution Approach 1:
The patch is divided into separate compartments: the battery part (magnesium and air electrode) and the active ingredient are physically separated during storage. This segmentation prevents unwanted reactions while allowing quick activation when brought into contact during use.
2Reliability
If the active ingredient is used in gel form to prevent liquid junction, then penetration into tissue is achieved, but the product form must be changed and storage contact with electrodes is required
Solution Approach 1:
The separator acts as an intermediary component that allows ionic conduction while preventing direct contact between the active ingredient and electrodes during storage. This enables the use of liquid or cream forms without requiring gel conversion or continuous contact.
3Power
If a general dry-cell battery is used for power supply, then sufficient power is provided, but harmful materials and rare metals are used increasing environmental load
Solution Approach 1:
The power supply system is changed from a conventional dry-cell battery to a magnesium-air battery system that uses environmentally friendly materials (magnesium, air, water) while providing sufficient power for transdermal delivery through controlled battery reactions.

AI summary
A biological tissue transdermal patch houses a battery part and an active ingredient such that they do not come into contact with each other. For the use of the biological tissue transdermal patch, the battery part and the active ingredient are brought into contact to start battery reaction of the battery part and the battery part is attached to a biological tissue. Carbonized bacterial cellulose or cellulose nanofiber carbon is used for a positive electrode of the battery part.
