Contact Lens Communication Electrode Mesh Design
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Contact lenses experience low communication sensitivity and slow communication speeds due to their small size and wet environment, which hampers wireless data transmission to peripheral equipment.
Innovation Solution
Incorporating a mesh-like or meandering linear communication electrode into the contact lens, which is designed to occupy a larger area without degrading visibility, and using transparent conductive materials like ITO, ITiO, IZO, or carbon nanotubes to enhance communication capacity and speed.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a large-area communication electrode is provided on the contact lens, then communication sensitivity and speed are improved, but visibility is degraded
Solution Approach 1:
The communication electrode is divided into multiple segments arranged in a mesh-like pattern, where individual electrode segments are separated by transparent intervals. This segmentation allows the electrode to cover a larger total area for improved communication while maintaining light transmission through the gaps, thus preserving visibility.
Solution Approach 2:
Different regions of the contact lens have different electrode densities - the mesh-like electrode is primarily provided in the peripheral region away from the visual axis, while the central region maintains higher transparency. This local differentiation optimizes communication performance in non-critical areas while preserving visual quality in critical areas.
2Reliability
If a mesh-like or meandering linear communication electrode is provided, then communication electrode capacity is ensured while visibility degradation is suppressed
Solution Approach 1:
The communication electrode transitions from a simple linear arrangement to a mesh-like two-dimensional pattern or meandering linear path. This dimensional change increases the effective electrode capacity and surface area for communication while distributing the electrode material more efficiently across the lens surface, reducing localized opacity and maintaining visibility.
