Developed by BASF, the Hertzstück is a groundbreaking infrared detector that could turn smartphones in pocket-sized laboratories. Designed to track the molecular content of food, the Hertzstück utilizes near-infrared spectroscopy. This process essentially has the device project light onto an object and then analyze the amount of light that is reflected back into the sensor. This reflected light is quite telling and the device can easily inform the users of what the material is and what it is mainly comprised of.
The Hertzstück was not designed with food primarily in mind, but the device was first showcased at the London Restaurant Festival. The display invited users to scan various foods, including an experiment that involved scanning through plastic packaging. All the results from this showcase were accurate and the device is now being geared towards health and wellness brands as a means of promoting healthy diets.
