Surface acoustic wave-induced mechanical stimulation

Surface acoustic wave-induced mechanical stimulation refers to the use of surface acoustic waves, which are electromechanical waves generated by applying an electrical signal to an interdigitated transducer patterned on a piezoelectric substrate[1][2]. These waves travel along the material surface and can induce controlled mechanical perturbations in cells or tissues abutting the substrate. Such stimulation has been used in experimental contexts to promote cell migration or modulate neural activity (neuromodulation), wound healing, and to actuate sensors and microfluidic devices[1][2][3][4][5][6]. Unlike a molecular target, this approach is a platform for delivering mechanical cues, rather than a discrete biological molecule or receptor susceptible to classical drug targeting. In summary, surface acoustic wave-induced mechanical stimulation is a physical process and not a canonical biological or drug target.
