 l interconnects can play a vital role in information transfer and transduc
 tion protocols. For that purpose\, we designed a waveguide that combines p
 rinciples of mechanical engineering\, condensed matter physics and topolog
 y. We show that wave propagation losses in these devices can be as low as 
 ~ 3 dB/km. We also demonstrate that only 0.01% of phonons propagating alon
 g the waveguide are scattered at sharp corners. Finally\, we discuss adjac
 ent developments related to observation of strong mechanical nonlinearitie
 s in membranes and a fast imaging protocol for obtaining resonant mode pro
 files.
