Radar-based technology has been around for decades but has seen massive changes. In particular, the size of the sensor arrays has shrunk in ways that are nearly impossible to imagine. Originally, radar sensors required huge dishes mounted on towers or domes around military installations. Today, thanks to Acconeer, these sensors are so small you can barely see one in the video.
This accomplishment by Acconeer is significant for a number of reasons. Of course, the accomplishment of making it small is, in itself, impressive. However, the really cool aspect is what is possible because of the size of the sensors. With large arrays, we were able to detect planes during World War 2. With the small arrays, we can accomplish equally impressive tasks for everyday life.
On the company’s website, they have a number of impressive demos for the technology. One of these demos is passenger detection in vehicles, which is a problem we’ve seen a lot in the past few years. Being able to detect if someone is in a vehicle, particularly children with no adult, could potentially save lives. The presence detection capability could be applied outside of a car, howe3ver, and make home security sensors more accurate, smaller, and more power-efficient.
Another interesting demo scenario surrounds liquids. These small sensors could be used to detect tank levels, in your water heater or even your gas tank. In the latter instance, the idea of a contactless sensor could end the common scenario of not trusting the gas gauge because it varies based on the angle of the car. Not having to rely on floating sensors means that the readings could be more accurate.
There are more examples of where these tiny sensors could be used. If you have an idea and would like to learn more or engage with Acconeer, check out their website.
