The document discusses Google's smart contact lens project announced in 2014. The lens contains sensors and electronics to continuously monitor glucose levels in tears to help people with diabetes. It consists of a glucose sensor and wireless chip embedded in the soft lens material. Data is transmitted via an antenna thinner than a human hair to a wireless device. Challenges include ensuring safety of LED lights and performance in various eye conditions.

2. ● Google project announced by GOOGLE in January 2014.
● The project aims to assist people with diabetes by constantly measuring
the glucose level.
GOOGLE SMART CONTACT LENS

6. DESIGN
● The lens consist of a wireless chip and a miniaturized glucose sensor.
● A tiny pinhole in the lens allow the tear fluid to seep in to the sensor to
measure blood sugar levels.
● Both the sensors are embedded between two soft layers of the lens material.
● The electronics lies outside of both the pupil and iris so there is no damage to
the eye.

7. ● There is a wireless antenna inside the lens that is thinner than a human hair
which will act as a controller to communicate information to the wireless
device.
● The antenna will gather read and analyze data.Power will be drawn from the
device which will communicate data via the wireless technology
RFID(Radio frequency identification).
● Plans to add small LED lights that could warn the wearer by lightning up
when the glucose levels have crossed above or below.

8. ADVANTAGES
● It is a simple and painless method.
● Continues glucose monitoring.
● Accurate reading - ensures efficiency and safe use.
● Reusable ( cost effective solution).
● Researchers have proven that the contact lens is less painful and time
consuming for diabetic than traditional finger pricking.

9. CHALLENGES
● Challenges presented by such a technology are that the LED Lights contain
the toxic metal ARSENIC.
● The performance of contact lenses in windy environment and teary eyes is
unknown.

10. CONCLUSION
● New technology.
● Continuousmonitoring.
● Non-invasive.
● Mobility for patients.
● Emerging markets.
