The first subterahertz data backscatter tag for large-scale signal sharing (IMAGE)
Caption
The silver tag sends information back to the reader in an experimental setup. The technology is an advanced version of a device that transmits data in a wireless system, commonly known as a tag. The new tag can support data transmission for a large network of devices using a technique called backscattering. This is where a central reader sends a signal to a sensor tag to gather information, and the tag reflects this signal directly back to the reader. This is the first backscatter tag that operates in the subterahertz frequency range. This frequency range makes it possible for the first time to use this technique for for large numbers of devices at once.
