Abstract

Wearable contact lenses which can monitor physiological parameters have attracted substantial interests due to the capability of direct detection of biomarkers contained in body fluids. However, previously reported contact lens sensors can only monitor a single analyte at a time. Furthermore, such ocular contact lenses generally obstruct the field of vision of the subject. Here, we developed a multifunctional contact lens sensor that alleviates some of these limitations since it was developed on an actual ocular contact lens. It was also designed to monitor glucose within tears, as well as intraocular pressure using the resistance and capacitance of the electronic device. Furthermore, in-vivo and in-vitro tests using a live rabbit and bovine eyeball demonstrated its reliable operation. Our developed contact lens sensor can measure the glucose level in tear fluid and intraocular pressure simultaneously but yet independently based on different electrical responses.

  • Tears were used for monitoring human eye intraocular pressure as an indicator for glaucoma using soft contact lenses for wireless detection of both glucose and intraocular pressure.

    “In addition, tears were used for monitoring human eye intraocular pressure as an indicator for glaucoma, which can cause blindness, using soft contact lenses for the wireless detection of both glucose and intraocular pressure [151].”
  • Although the smart contact lens device is capable of multiplexed sensing, the simultaneous demonstration of two functionalities has not yet been evaluated.

  • Smart contact lenses for wireless ocular diagnostics have been developed by combining glucose and ocular pressure contact lens sensors for wireless in vivo glucose monitoring in the eye of a rabbit, together with in vitro monitoring of ocular pressure using a bovine eyeball.

    “Recently, ‘smart’ contact lenses for wireless ocular diagnostics have been further developed by combining glucose and ocular pressure contact lens sensors for wireless in vivo glucose monitoring in the eye of a rabbit, together with in vitro monitoring of ocular pressure using a bovine eyeball (Fig. 5b)117.”

  • The tear sensor is designed to detect glucose level in tears and measures intraocular pressure by utilizing resistance and capacitance properties.

    “It is specifically designed to detect the level of glucose in tears and measures intraocular pressure by utilizing the resistance and capacitance properties.”
  • A tear sensor using a graphene field-effect transistor integrated with a graphene-silver nanowire composite antenna works at radio frequency and wirelessly transmits sensory information upon glucose oxidation on the graphene channel.

    “For instance, as shown in Fig. 2f Kim et al. introduced a tear sensor using a graphene field-effect transistor (FET) integrated with a graphene-silver nanowire (AgNW) composite antenna, which works at radio frequency and wirelessly transmits sensory information upon the occurrence of glucose oxidation on the graphene channel (Kim et al. 2017).”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
