Introduction
Have you ever thought of a camera that doesn’t 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 seems that the research team has designed a pixel that measures the 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 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 around the world 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 yet compact cameras with tech-savvy customers in mind. In such a scenario, your 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-contained. Components installed in the camera measure light and convert it into electrical energy. The developers say that they have installed an image sensor with 30×40 pixels An image sensor chip will have millions of pixels. Each pixel generally has a photodiode to produce electricity when light falls on 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 power 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 high capacity and self-recharging battery.
