EPFL Engineers Develop Sound-Powered Micro-Robots Without Motors or Batteries
Engineers at Switzerland’s École Polytechnique Fédérale de Lausanne (EPFL) have developed a method to convert sound waves into directional thrust, enabling the creation of micro-machines that operate without motors, batteries, or electronics. This innovative technique utilizes Helmholtz resonance, where sound excites air within a cavity, generating propulsion through airflow imbalance. This advancement is significant as it allows for the design of small boats and ultralight aerial vehicles powered solely by sound, eliminating the need for traditional power sources. The EPFL team’s approach, which involves 3D-printed hollow cavities, represents a shift from previous acoustic levitation methods, offering a new way to achieve self-generating thrust through concentrated air jets. Looking ahead, the potential for further miniaturization of these sound-powered devices could revolutionize robotics and aeronautics. Researchers have already demonstrated prototypes at both centimeter and microscopic scales, showcasing capabilities such as controlled navigation and impressive lift, indicating a promising future for passive materials in robotic applications. No further timeline was disclosed at the time of publication.

Army Urges Industry for Innovative Power Solutions Beyond Batteries and Generators
The U.S. Army has identified a critical shortage of exportable power in its ground vehicles, which hampers the operation of drones and communication systems. Brig. Gen. Troy Denomy emphasized the urgency for industry to develop solutions, as the Army faces increasing power demands from new energy-intensive weaponry. Current vehicles like the M1A2 Abrams and Bradley Fighting Vehicles lack the capacity to support these systems, leading to operational limitations for brigade commanders. This power deficiency is significant as it affects the Army's ability to deploy unmanned aerial systems (UAS) effectively. Denomy highlighted that commanders are forced to limit UAS operations not based on mission needs but rather on available power. The reliance on noisy generators and additional battery packs is not a viable long-term solution, as these options compromise stealth and increase the burden on soldiers. Looking ahead, the Army is exploring advanced technologies, including fuel cells, to enhance power generation in legacy vehicles. Newer models like the XM30 and M1E3 Abrams are designed to provide greater exportable power. The Army is also investigating next-generation power management solutions and alternatives to traditional liquid fuels to address these challenges.
