Engineers have successfully developed an infrared imager with the help of which we can see through different types of mediums. Lots of engineers were working on this so as to provide the best service which would solve our problems, and the best part of the discovery is that we could be able to see through smog and fog it would be very easy to locate the blood vessels present in our body. We could also fix the problem which is majorly found in the electronics, and so we are able to detect the and see-through electronic boards. It is very much handy and portable. It is slim, compact, and less costly to fabricate than similar technologies.

The imager detects part of the infrared spectrum, called short-wave infrared light (wavelengths 1000-1400 nanometers), which is just outside the visible spectrum (400-700 nanometers). Detects much longer infrared wavelengths emitted by the body. "It makes invisible light visible, says Tina Ng, professor of electrical and computer engineering at the Jacobs School of Engineering at UC San Diego. Although infrared imaging technology has been around for decades, most systems are expensive, bulky, and complex and often require a separate camera and display.

Infrared imagers are typically made from inorganic semiconductors, which are expensive, rigid, and made up of toxic chemicals like arsenic and lead. The infrared imager developed by Ng’s team overcomes these problems. It combines the sensors and the screen in one slim device, making it compact and simple. It consists of organic semiconductors, which makes it inexpensive, flexible, and safe to use in biomedical applications. It also offers better image resolution than some of its inorganic counterparts. The new imager, which was recently published in Advanced Functional Materials, offers additional advantages. It sees more of the short-wave infrared spectrum, 1000-1400 nanometers, existing similar systems often only see the largest infrared screen sizes below 1200 nanometers—previous imagers: 2 square centimeters area. And since the imager is manufactured using a thin-film process, it can be easily and cost-effectively scaled to make even larger displays.
