Acoustic propulsion is a method of using sound waves to generate movement or force. This technology harnesses the energy from sound vibrations to propel objects, often in fluids like water or air. It can be applied in various fields, including marine engineering and medical devices. One notable application of acoustic propulsion is in sonar systems, which use sound waves to detect objects underwater. Additionally, researchers are exploring its potential in microbots for targeted drug delivery, where sound waves can guide tiny robots to specific locations within the body.
