Introduction
Have you ever thought of a camera that does not need a battery to work? It has become a reality thanks to the efforts of a group of researchers led by a scientist of Indian origin. It would be the world’s first self-powered video camera. The researchers claim that it produces an image every second. It appears that the research team has designed a pixel that measures incident light and converts it into electrical energy. In this article, we will discuss the features of the self-powered camera for the benefit of the readers.
Importance of the discovery
Under the technical supervision of Shree K. Nayar, a team from Columbia University has developed this beautiful camera. He works as the TC Chang Professor of Computer Science at Columbia University. The world is going through a period of digital revolution. The companies sold about 2 billion cameras of various types worldwide last year. Many of the cameras sold in recent years have used the latest in digital imaging technology. The company has used this technology in many wearable devices, smart environments, sensor networks, and personalized medicine. As for the response and trend, well-known brands in the field of digital imaging have started to develop advanced and compact cameras with tech-savvy customers in mind. In such a scenario, its development camera without external power supply would be a welcome trend in the digital imaging market.
The world’s first self-powered camera
This camera uses the same set of components to become self-sufficient. Components installed in the camera measure light and convert it into electrical energy. The developers say they have installed an image sensor with 30×40 pixels An image sensor chip will have millions of pixels. Each pixel usually has a photodiode to produce electricity when light strikes it. The same unit has an extension to generate current from electricity. This dual functionality helps the camera produce images at a better rate and draw energy from light. In addition, the incorporation of two functionalities in the same part has reduced the weight and size of the new camera. Therefore, users can hold this camera with ease. They can even hold it in the palm of their hand while taking a photo. If the camera is bulkier, it would be difficult to focus on a distant object and the shots would become blurry. Also, users will have more time to shoot a movie with this camera as it has a self-recharging and high-capacity battery.
