New Bionic Eye Lens

Bionic Eye Lenses or Bionic Contact Lenses are of the latest inventions of the decade that are being used by visually impared people inorder to get some assistance in their sight. This bionic lens is actually a simple contact lens, super-imposed by the bionics technology. Bionic lens is manufactred from bio-compatible and bio-sustainable compounds via microfabrication.



These lenses have a built-in electronic circuit whose thickness is not more than few nano-meters. This electronic circuit contains a solar assembly, tele-communication panel, display control unit and a matrix of tiny LEDs (Light Emitting Diodes), all scaled-down to nano-level!

The solar assembly consists of solar cell, an energy converter and energy storage area which are combined so as to generate and store the energy required to run the circuit. The tele-communication panel consists of antennas that can capture light in the form of electromagnetic waves. The light waves when captured are sent to display control unit, which processes the image and glows the LED matrix such that the image is formed. In the LED matrix, LEDs are placed 250 to 300 nanometers away from each other. The distance between LEDs and size of matrix co-effect the sharpness and distance of the vision.

Currently, scientist are able to produce such lens that can generate sharp vision upto 10 meters which will greatly help the people having visual impairment. 

The Medical Radio

You might surely have heard the local radio broadcasts... any news.. or any of your favorite song... via tuner or your television set or may be via your mobile set or even from internet! And most of you, do surely know that these radio broadcast are actually the wide scale transmission of a bunch waves known as radio waves but... many of you don't even know these bunch of "broadcast waves" are used in "medical field" as well! 

Well... Yes! It is correct and what's more...! these waves have been in practise from more than 75 years!

These waves are used for many medical purposes like...

• Generate live images of what is going on inside the body (See the video)
• Rejuvenation and tightening your skin (See the video)
• To lessen the extra bit of fat in the body
• Burn cancerous tissues (Read page 236 of the book)
• Treatment of bone tissues from various diseases (Read this article)
• Treatment of sleep apnea i.e. treats the breathing problem during sleeping
• To cease excessive bleeding
• To cut the skin for surgery
• Muscle relaxation

Non-Invasive Glucometer

Diabetes is one of the major problems in not only Pakistan but also in the world. This disease is no more than a "silent killer" which malfunction the human physiology at a snail's pace. Diabetes can be easily defined as “the disorder of insulin function or production”. In diabetes, the glucose level in the blood deviates from the normal levels, due to the lack of insulin quantity or due to the disturbance in the insulin function. This disturbance in glucose levels can be easily controlled through synthetic insulin delivery. But, here a can question can arise that how do we know about the disturbance in the blood glucose concentration?

The answer to this question is quite simple. A blood glucose meter can used to keep track of the blood glucose levels. Currently, there are glucose meters which can be used as a household medical device (like, a thermometer in your home!). Some of the household medical devices require a complete drop of blood from you while others require less than a blood. Some of these glucose meters are automated but, most of them are manual. For, manual glucose meters you have to prick your blood by yourself through a lancet or pricking gun (and ouch, it is really painful). The automated glucose meters does not require manual pricking, they just suck your blood automatically in very few amounts (usually, half the drop of blood). The pricking or sucking sites are mostly fingers. These devices are called invasive glucometers.

The research for the quest of a novel blood glucose meter that doesn’t require any blood is continuing since 40 years and, up till now many methodologies have been implemented to produce such devices. The most famous of them are through reflection, refraction and/or scattering of either infrared rays or ultrasonic waves. You just only have to wear a ring or a clip on your finger or wear special glases on your face or even wear it on ears like ear tops! And lo! Bingo! You will get your blood sugar level. These devices are collectively known as non–invasive glucometers.

Non-Invasive glucose meter are better than the invasive ones. Not only that invasive glucometers require blood and pricking but also they need glucose strips. Glucose strips have a significant running cost which have to be beared by the patient. Non-invasive ones are cheap, user–friendly and comfortable. They also have very low running cost. Scientists, engineers and industrialists believe that by 2013, the commercialization of glucose meters will start and people will feel much comfortable when using these machine.
