Tiny 3D printed robots take flight on sound alone.
Forget batteries and motors: researchers at the MicroBioRobotic Systems lab at France's EPFL 3D printed tiny robots that fly on sound. Each microflier contains tiny air-filled cavities that work a bit like a bottle when you blow across its opening: hit it with the right frequency the trapped air starts vibrating strongly enough to thrust the robots airborne and enable researchers to steer them remotely. The robots were resin 3D printed using two-photon polymerization tech on a Nanoscribe Photonic Professional GT+.
