The nano-guitar string that plays itself

Mon, 10/14/2019 - 19:17
Scientists have created a nano-electronic circuit which vibrates without any external force. Just as a guitar string vibrates when plucked, the wire -- 100,000 times thinner than a guitar string -- vibrates when forced into motion by an oscillating voltage. The surprise came when they repeated the experiment without the forcing voltage. Under the right conditions, the wire oscillated of its own accord. The nano-guitar string was playing itself.
