A team of researchers at Nagoya University has discovered something surprising. If you have two tiny vibrating elements, each one barely moving on its own, and you combine them in the right way, their combined vibration can be amplified dramatically—up to 100 million times.

The paper is published in the Chaos: An Interdisciplinary Journal of Nonlinear Science.

Their findings suggest that by relying on structural amplification rather than power, even small, simple devices can transmit long-distance clear signals, potentially innovating long-distance communications and remote medical devices.
