Abstract With the development of engineered nanomaterials and nanomedicines, utilization to generate excessive reactive oxygen species under exogenous ultrasound (US) irradiation for realizing disease therapy, namely sonodynamic therapy (SDT), has attracted widespread attention. Compared with traditional photodynamic US shows deeper tissue penetration reach deep‐seated location. However, high‐efficiency sonosensitizers remains one gravest challenges in current related research future clinical application. Latterly, benefiting from piezotronic piezo‐phototronic effects, novel based on piezoelectric semiconductor (PS) have exhibited inspiring application prospects SDT. In this review, we outline structures physicochemical properties PS that potential applications SDT, introduce presumed mechanisms Then, latest progress as cancer antibacterial are summarized.
