The authors introduce a MEMS device that leverages the destructive interference between two topological radiofrequency (RF) counter-propagating wave modes at a piezoelectric Aluminum Scandium Nitride (AlScN) Su-Schrieffer-Heeger (SSH) interface. This device offers enhanced sensing capabilities compared to conventional NEMS/MEMS, particularly for localized parameters such as the mass of a single cell.
