Smart overview of the Invention

The patent application discusses a novel contact lens design incorporating integrated electronic components. These lenses are crafted from hydrogels and encapsulate electronics such as sensors, batteries, and microfluidic channels. This encapsulation ensures that the electronics are safely enclosed within the lens material, addressing biocompatibility concerns and maintaining user comfort by keeping the lens thin.

Field of Invention

This development pertains to smart contact lenses featuring embedded electronics. These lenses offer enhanced functionality for vision correction, health monitoring, and potential drug delivery. The invention emphasizes scalable and cost-effective production methods, which are crucial given the delicate balance required between safety, comfort, and technological integration.

Background

Advancements in flexible electronics have led to various health-related applications. However, integrating such technology into contact lenses poses challenges, particularly regarding safety and comfort. Traditional methods either expose electronics to the eye or result in lenses that are too thick. The present invention seeks to overcome these issues by fully encapsulating electronic components within the lens material.

Technical Details

  • Materials: The hydrogel may include substances like polyvinyl alcohol and silicone.
  • Components: Electronics can include sensors, batteries, supercapacitors, and microfluidic channels.
  • Thickness: Lens thickness is controlled between 0.05 mm to 0.5 mm for comfort.
  • Pharmaceuticals: Lenses can be impregnated with drugs for controlled delivery.

Production Method

The production process involves heating a solvent and combining it with a hydrogel precursor to form a hydrogel matrix. This matrix is then molded around the electronic components to create the contact lens. The method allows for simultaneous production of multiple lenses using molds with multiple wells, ensuring efficiency and scalability in manufacturing.
