PurdueUniversityresearchers have actually established soft contact lenses that not just proper vision however likewise can monitor glucose and medical conditions and be utilized for ocular discomfort relief or drug shipment.

Sensors or other technology formerly could not be utilized for soft contact lenses due to the fact that the technology needed a stiff, planar surface area incompatible with the soft, curved shape of a contact lens.

ThePurdue University group, led by Chi Hwan Lee, an assistant teacher of biomedical engineering and mechanical engineering, produced an unique technique for connecting sensing units and other little gadgets to soft contact lenses.

“We developed a very unique technology that enables the integration of thin film sensors with a commercially available soft contact lens,”Lee stated. “These current hydrogel-based contacts serve as the perfect platform for smart lens systems due to their high degree of comfortability, biocompatibility, breathability and long-term wearability. Before our discovery, it was challenging to fabricate high-performance electronics on commercially available soft contact lenses.”

The sensing units embedded on the soft contact lens discover the levels of glucose, lactate and pH worth in a constant way, offering info connected with diabetes, hypoxia and underlying ocular tissuehealth With the capability to integrate soft, silicon-based contact lenses with a range of various semiconductor gadgets, various innovative eye care applications are now possible.

“This technology is highly novel and will significantly expand the functionality of existing soft contact lenses,”Lee stated. “This technology will also form a basis to further extend the functionality of the smart soft contact lens system for many other envisioned applications, including controlled release of ocular drugs, eye-wearable night vision and augmented reality.”

Lee’s group is continuing to test the mechanical and electrical homes of the lenstechnology The PurdueOffice of Technology Commercialization assisted protect a patent for the technology and it is offered for licensing.
