Imagine a technology that can examine a material without touching it. There is no need to open a package, lift a blanket, or place a sensor directly on the body. Instead, the technology sends signals in the millimetre-wave range and analyses the reflections that return. This is the foundation of XFinder’s technology – using radar as a kind of new sense to understand what is happening around us.
What makes the approach different is the use of multiple frequency bands within an extremely short period of time. Each frequency can respond differently to the properties of what is being examined. Some may be more sensitive to factors such as water, while others provide information about structure, density, or surface characteristics. When all these reflections are collected, they create a complex pattern – a kind of electromagnetic fingerprint. It is this pattern, rather than a single signal, that the system analyses.
The next step is interpreting the pattern. The computer can compare a current measurement with previously known patterns while continuously learning from new observations. It can be compared to how we recognize a familiar voice: we do not listen for just one tone, but perceive the whole picture. In a similar way, the system attempts to understand the overall pattern of radar reflections and identify which previously known pattern the current situation most closely resembles.
An important feature is that measurements can be made without physical contact. The technology can, for example, work through everyday barriers such as clothing, packaging, and bed linen. This means that information can be collected without requiring a person to undress or wear a physical sensor.
This opens up many possible applications. In healthcare and care environments, the technology can, for example, be used to monitor certain conditions without disturbing the person. In industry, the same basic principle can be used to examine the contents of a sealed container without opening it. The common idea is simple: to understand more by reading the overall pattern rather than relying on a single measurement.
XFinder’s technology is therefore based on a simple but powerful idea: sometimes, we do not need to touch something to understand what is happening. We simply need to be able to read the right signals.
