Oh, patents! Glucose-monitoring contact lens

Copyright © Françoise Herrmann

Yes, that’s right, smart contact lenses, comprising Lab-on-a-Chip (LOC) nanotechnology, that continuously measures and analyzes glucose levels in tear film, sending information to your mobile device for the management of diabetes. In a nutshell, this is what the Medella Health smart contact lenses are all about: paving the way for on-eye tear diagnostics. Pioneers in smart contact lenses, because beyond nano-glucose monitoring, tear film contains many important biomarkers of health, all of which are potential sources of personal health information. 

The YouTube video below explains how the smart lens works:



Winner of an International Runner-up James Dyson Award, the many aspects of the Medella Health smart contact lens, comprising LOC or Micro Total Analysis System (µTAS), are recited in a family of patents:
  • CA2948010A1Functional contact lens and related systems and methods.
  • CN106793943BFunctional contact lens and related systems and methods.
  • EP3131454A4 - Functional contact lens and related systems and methods.
  • US20170042480A1 - Functional contact lens and related systems and methods.
  • WO2015157855A1 - Functional contact lens and related systems and methods.
The US20170042480A1 abstract, of the Medella Health smart contact lens invention, is included below.
Various embodiments are described herein for a Functional Contact Lens (FCL) for detecting at least one target analyte. The FCL may comprise a substrate for supporting electronic components and providing structural support for the functional contact lens; at least one sensing element disposed on the substrate for sensing the at least one target analyte and undergoing a physical change representing a sensed signal; and an antenna disposed on the substrate for transmitting the sensed signal to an external device, the antenna being coupled to the at least one sensing element.
