With the tons of 21 megapixel cameras out there it may seem strange that a 20-pixel camera has the scientific community buzzing. That is, until you consider the fact that this camera is so tiny it can fit on the head of a pin.
Researchers at Cornell university have developed the microscopic camera with no lens or moving parts. The camera is only a hundredth of a millimeter deep and half a millimeter on either side and made from doped silicon, a very inexpensive material. In fact, the camera costs only pennies to make, making it perfect for a myriad of different applications, particularly in the medical and robotics industries.
The camera was originally developed by Alyosha Molnar and Patrick Gill to be implanted near a living brain in order to measure brain activity by picking up light from specific neurons. The pair published their work in the journal 'Optics Letters' just last week, but industries across the globe are already taking notice. Technology like this has potentially hundreds of applications in robotics and medicine and many are already brainstorming on how they can use the camera to improve products in development.
