Cameras the Size of a Grain of Salt
In today’s world, small-sized things are a crucial trend. Computers that were once room-sized are now palm-sized. We are living in that world where a micro-size ship holds more data than a room filled with files.
Sensors that once weighed so heavy that they could hardly be held in a hand now fit inside your smartphone. But the world and its inventions do not end here. The scientist has created a camera that is the of a grain of salt. Yes, you heard it right. A camera that is so small that it could be almost invisible to the naked eye.
Each camera is 120 millionths of a meter in diameter. As far as its diameter is concerned its diameter is nearly equal to the size of human hair. This dimension makes it the size of table salt. Since these cameras are made in one piece they can be made more complex in the upcoming times which will result in taking the finest quality images.
The better and improved version of these cameras will be capable of including single, double, and triple optical lenses and the image can be printed on the standard paper used in the field of medicine. These devices will make the procedure of endoscopy less invasive. Even, its benefits do not end here it can be injected into the brain by placing it at the start of the syringe and then injecting it into the body.
Apart from their medical applications, these can also be utilized in the Department of Intelligence, where they can be integrated into miniature drones and robots. They can also help in keeping the security of the areas.
The best part about these devices is they can be produced on a commercially available 3D printer which means that it can be produced at a small scale and their realization is not limited to highly specialized multi-million dollar labs.
Now the researcher is working on making the lens quality better. I’ve noted down the text.
