Engineers at Purdue University and GlobalFoundries have gotten today’s most advanced transistors to vibrate at frequencies that could make 5G phones and other gadgets smaller and more energy efficient. The feat could also improve CPU clocks, make wearable radars, and one day form the basis of a new kind of computing. They presented their results today at the IEEE International Solid-States Circuits Conference, in San Francisco.
