A small, cheap, and low-power mesh-type piezoelectric ultrasonic transducer (MPUT) from a household USB humidifier has been developed as a sonochemiluminescence generator for the first time. The ultrasonication of an MPUT facilitates the generation of reactive oxygen species to trigger sonochemiluminescence. There is no light emission of luminol without sonication. In contrast, the luminescence becomes very intense by ultrasonication using the MPUT and can be readily observed by a smart phone, enabling the visual detection of luminol wit
