Bionic Eyes

In a pioneering research, scientists claim to be developing bionic eyes for the blind, which they say will be ready for human trials by 2013.

Here’s a brief explanation of bionic vision system or bionic eye:

What is bionic eye?

Bionic Contacts Lens

This lens is based upon Bionic Technology, but it’s not a Bionic Eye.

Bionic eye is an experimental visual device intended to restore the sense of vision to people living with blindness, low vision, or age-related macular degeneration.

Bionic eyes or bionic vision system consists of a camera mounted on pair of glasses, the purpose of this camera is to transmits visual information or high-frequency radio signals to a microchip( or electrode array) which is connected to neurons in the retina. Electrodes on the implanted chip convert these signals into electrical impulses and then these electrical impulses are transmitted through the optic nerve to the vision centers of the brain where they are interpreted as an image. The detail of a generated image by this technology depends on phosphene. A phosphene is a perceived spot of light in the visual field which can be induced with the help of electrodes. It means the more electrodes are implanted, the more phosphenes are capable of being generated and the more detail a patient may be able to see.

A person using this device or technology won’t experience vision in the same way that a person with a healthy eye does but with training and patience people will adapt to the implant. This technology is in its initial stage and with time and more research, it is possible that in future this technology can help patients living with blindness and low vision to recognize faces, read large print and much more. It is also possible with the more research and advancement in the field of bionic vision systems, there will be high-resolution and visual quality bionic eyes and will be commercially available which can even provide better vision than normal eyes. It might be possible that even healthy people will upgrade their sight with these kind of devices.

The future of electricity transmission

Day by day, technology is advancing very rapidly; there will be many changes in coming decades in the world of technology and one of them will be wireless transmission of electricity. Yes, in the coming few decades electricity will be transmitted without the use of wires.

The first person to actually make wireless transmission of power possible was Nikola Tesla. Tesla demonstrated wireless energy transfer to power electronic devices in 1891, and aspired to intercontinental wireless transmission of industrial power in his unfinished Wardenclyffe Tower project and still wireless transmission of electricity is a field of research. It might be possible that this technology will come into existence in few decades.

Here’s something about this technology:

Primarily, this technology may starts from mid-range transmission methods that could charge or even power portable devices such as cell phones, laptops, PDA and all that kind of devices or possibly all other range of electric and electronic appliances. And for sure, this technology will going to eliminate the need for multiple wall sockets and bulky cables and will greatly reduce clutter in homes and offices. In place of batteries, electronic devices will have antennas to draw power from a single power node mounted in the ceiling or in the wall of a room. Electromagnetic waves are transmitted through the air from the device present in the ceiling or in the wall. These waves are then received by the device like cell phone or other appliance through their receiving antenna. And in this way electricity will be transmitted without using wires. So definitely, there will be new way of transmission of electricity in the coming decades, maybe by the late 2020s.
