Abstract

Provided is a smart contact lens for non-invasive drug delivery including a platform configured to be worn on an eye, a reservoir installed within the platform, and having a receiving part in which a drug is received, to provide the eye with the drug, an electrode for iontophoresis installed in the reservoir to make iontophoresis work, to provide the eye with the drug from the reservoir, and an activation chip electrically connected to the electrode for iontophoresis to activate iontophoresis.

First claim

What is claimed is:

1. A smart contact lens for non-invasive drug delivery, comprising:
a platform configured to be worn on an eye;
a reservoir installed within the platform, and having a receiving part in which a drug is received, to provide the eye with the drug;
an electrode for iontophoresis installed in the reservoir to make iontophoresis work, to provide the eye with the drug from the reservoir;
an activation chip electrically connected to the electrode for iontophoresis to activate iontophoresis,
a power transmitting structure electrically connected to the activation chip to supply external power to the activation chip; and
a power storage electrically connected to the power transmitting structure to receive the external power from the power transmitting structure and store the external power,
wherein the reservoir includes:
a support surface installed within the platform;
a supply surface disposed opposite the support surface to provide the eye with the drug;
a plurality of pillars interposed between the support surface and the supply surface to extend from the supply surface to the support surface in a direction perpendicular.

2. The smart contact lens for non-invasive drug delivery according to claim 1 , wherein the receiving part is provided between the support surface and the supply surface with the pillars interposed between.

3. The smart contact lens for non-invasive drug delivery according to claim 1 , wherein the supply surface has a supply hole to provide the eye with the drug.

4. The smart contact lens for non-invasive drug delivery according to claim 1 ,
wherein the pillars are spaced apart from each other in a space between the support surface and the supply surface.
