Chips can infect people through the air Researchers from Northwestern University in the USA, together with colleagues from China, Korea and the UK, have developed a micro-propeller shape that allows you to stay in the air for as long as possible when falling from a great height, and also provides movement control over a large area. "Our goal was to add flight capability to small electronic systems, with the idea that this new capability would allow us to distribute highly functional miniature electronic devices (chips)," lead author John Rogers, who led the research, said in a university press release, professor of materials science and engineering, biomedical engineering and neurological of McCormick School of Engineering and Feinberg School of Medicine. To determine the ideal configuration, the scientists performed full-scale digital simulations of how air flows around the device to simulate the slow, controlled rotation of the tristellatea semen. Based on this simulation, the authors built miniature devices and tested them in the laboratory using advanced visualization and quantification of flow parameters. natural qualities. The authors have already tested devices equipped with sensors, power supplies that harvest energy from the environment, memory and an antenna that can transmit data wirelessly to a smartphone, tablet or computer. In one test, they used flying microchips to detect particulate matter in the air, and in another to determine the pH of water vapor and measure sunlight at different wavelengths.
