An international team of researchers (Finland, Russia) has developed a new method for collecting data from passive wireless nanosensors using devices which can measure the parameters of objects and convert them into a signal. They use microscopic nanoelements and do not have an integral battery pack. They do not require any maintenance, have a long service life and low cost. Mathematicians have modeled an experiment with gateways, which are made on the basis of unmanned aircraft. THz frequency range is used for the wireless energy transfer to nanodevices as well as for communication with them. The energy harvested from electromagnetic waves which are radiated by the UAV-based gateway provide sufficient power for the functioning of the passive nanosensor and signal transmission to the gateway. It has applications in monitoring scenarios, control of the soil state in agriculture, environmental pollution monitoring, and the control of linear objects (pipelines, dams, dikes)…read more.
