Smart lens for Diabeties

  1. 1. SMART LENS Presented by: K. Rani Samyuktha Dept. of Pharmaceutical Analysis NIPER-HYDERABAD 11/4/2016
  2. 2. EXISTING AND PROPOSED SYSTEMS EXISTING SYSTEM The traditional method of using a lancing device is disruptive and painful and needs to be done repeatedly through out the day PROPOSED SYSTEM The project aims to assist people with diabetes by consistently measuring the glucose levels in body 11/4/2016 2

  4. 4.  SENSORS: Embedded between 2 soft layers of lens material & a pinhole in the lens allows fluid to sweep into sensor and measures glucose levels.  WIRELESS ANTENNA: Communicates information to the wireless device.  Adding led lights to warn the wearer when glucose levels crossed threshold.  Readings available at a tap on your phone.  App can be used by others, they can monitor your blood glucose levels. 11/4/2016 4
  5. 5. HOW DOES IT WORK? Lens consists of proprietary combinations of boronic crystals and other chemicals Boronic crystals react with glucose in tears Molecular spacing between chains in array changes 11/4/2016 5
  6. 6. HOW DOES IT WORK? Initiation of chemical reaction Causes lens to shift their hues Causes change in colour of lens Working can be compared to pH Paper: Ph paper - Hydrogen ion concentration Smart lens – Glucose concentration 11/4/2016 6
  7. 7. Advantages Reusable Painless Highly reliable Mobile accessible Patient compliance Novel drugs delivery system 11/4/2016 7
  8. 8. Smart lens as novel drug delivery system Tiny chambers are carved into the hydrogel and drug is added and covered with a thin gold electrode membrane User can use voice commands to tell app to send drug- releasing signal to the chip Chip initiates a voltage Membrane dissolves and releases the drug 11/4/2016 8
  9. 9.  Developed by Google partnered with, pharma company Novartis eye care division.  Patented by Google in March 2015  Human trials started in 2016  Released around 2019 11/4/2016 9
  10. 10. CONCLUSIONS: • Smart way to monitor and control diabetes. • Rising novel drug delivery system. REFERENCES : 2.Wikipedia 9
