Eddie Gonzales Jr. – MessageToEagle.com – Researchers at ETH Zurich have made sound waves travel only in one direction. In the future, this method could also be used

To turn ‘on’ an acoustic transistor, ultrasound arriving at the ‘gate’ input heats and expands the base plate, changing the spacing in two lattices of slightly-different-sized pillars, and inducing a topological transition that guides sound along the interface. (Credit: Hoffman Lab/Harvard SEAS)
