A new algorithm allows drones to fly completely by themselves through the streets of a city and in indoor environments. The algorithm had to learn traffic rules and adapt training examples from cyclists and car drivers.
Scientists have used inverse design principles and a 3-D printer to create highly efficient broadband metadevices at millimeter-wave frequencies that could prove revolutionary for consumer products, defense, and telecommunications.
Researchers have demonstrated that sound waves can be used to produce ultraminiature optical diodes that are tiny enough to fit onto a computer chip. These devices, called optical isolators, may help solve major data capacity and system size challenges for photonic integrated circuits, the light-based equivalent of electronic circuits, which are used for com […]
Engineers have designed an artificial synapse in such a way that they can precisely control the strength of an electric current flowing across it, similar to the way ions flow between neurons. The team has built a small chip with artificial synapses, made from silicon germanium. In simulations, the researchers found that the chip and its synapses could be us […]
