Abstract
A radiofrequency-powered device such as a wireless passive sensor node, for instance, comprises a radiofrequency energy harvesting circuit configured to be coupled to an antenna to harvest radiofrequency energy captured by the antenna from a radiofrequency signal. The radiofrequency energy harvesting circuit is configured to be coupled to an energy storage component to store therein energy harvested via the radiofrequency energy harvesting circuit. The device comprises user circuitry configured to be supplied with energy harvested via the radiofrequency energy harvesting circuit and to operate in accordance with one of a plurality of configurations as a function of configuration data supplied thereto. A receiver circuit coupled to the radiofrequency energy harvesting circuit is configured to receive a configuration data signal modulating the radiofrequency signal and supply to the user circuitry configuration data extracted from the configuration data signal received.
