The idea of having a camera to record an image is giving way to the goal of having ways to pick up photons and work out the image we would like to have. A first sign appeared a few years ago with the inclusion of the histogram on cameras. Probably, …

Digital image sensors are actually … analogue. They are -sort of- buckets that gets filled with (many) photons. The level of filling during an exposure is converted in a specific voltage that is used by the camera software to associate a certain level of brightness (it is a bit more …

There are so many ways to transform analogue into digital and yet new ones keep popping up. Look at what researchers at Dartmouth University have presented at UIST 2017: an ingenious way to detect the movement of your thumb on your index fingertip using an infrared sensor (watch the clip). …

Researchers at Caltech have been able to create a chip that mimics the properties of MRI, a very bulky machinery, so tiny that it can be injected in the body, through arteries, or can be swallowed to explore the gastrointestinal tract. The micro chip is in shape of a cube, …

A team of researchers at Austin University has announced the creation of a sensor, in shape of a pen, that can detect molecules for spectroscopy analyses leading to the detection of cancerous cells. The pen is 3D printed and is used by a doctor to touch a tissue, both in …
