Organic–Inorganic Hybrid Perovskite Materials for Ultrasonic Transducer in Medical Diagnosis

The ultrasonic transducer is considered the most important component of ultrasound medical instruments, and its key active layer generally fabricated by piezoelectric materials, such as BaTiO3, Pb (Zn, Ti)O3, PVDF, etc. As star material, perovskite photovoltaic materials (organic inorganic halide CH3NH3PbI3, CsPbI3, etc.) have great potential to be widely used in solar cells, LEDs, detectors, photoelectric detectors due their outstanding effects. Herein, we firstly discussed research progress commonly corresponding effects, current scientific status, well application status field medicine. Then, further explored piezoelectric-effect devices, difficulties. Finally, designed an ideal future prospects organic material ultrasound.
