Backscattering is a form of wireless transmission based on modulated reflection of external RF signals. Whereas conventional radios generate their own signals, backscatter radios transmit data by making tiny changes to reflected signals. This approach requires a minimal number of active components, promising simple low-cost battery-free operations.   Since the source …

Artificial intelligence is a branch of computer science dealing with the simulation of intelligent behavior in computers. A computer system able to perform tasks that normally require human intelligence, such as visual perception, speech recognition, decision-making, and translation between languages. Machine learning is a subset of AI.  AI has a …
