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

“…Piezoelectricity is caused by crystal deformation, the coupling of electrical and mechanical states of a material. Under mechanical strain and deformation, the positive and negative charge centers in piezoelectric materials migrate, resulting in an external electrical field and current flow (Katzir, 2003(Katzir, , 2007Panda et al, 2022;Preetam & Panda, 2021). The inverse is also feasible.…”

Piezoelectric biosensors are a type of analytical equipment that works based on recording affinity interactions. A piezoelectric platform, also known as a piezoelectric crystal, is a sensor component that works on the premise of oscillations changing according to the presence of a mass on the piezoelectric crystal surface. Owing to their high piezoelectricity, biocompatibility, as well as different electrical properties, biomolecular piezoelectric materials are thought to be promising candidates for future piezoelectric biosensors. When biological components in the human body are stressed, they are estimated to produce electric fields that promote cell growth and repair. As a by-product, piezoelectricity research in biological tissues and their elements has drawn much attention recently. This article specifies the principle of the advancement in piezoelectricity research of representative biomolecular materials, which are nucleic acids such as amino acids (DNA, RNA), peptides, proteins, and viruses. We also explored the origins and processes of piezoelectricity in biomolecular materials for biosensor application. Various advantages of using piezoelectric biomolecular materials for biosensor applications are elaborated. Lastly, a comprehensive idea of future challenges and discussion are provided.

“…Piezoelectric sensors may generate their own power by the application of mechanical stimulation, in contrast to more conventional sensors, which need an external power supply to function [ 17 ]. Piezoelectric energy harvesters are a promising contender for self-powered bio-applications since they have the ability to transform mechanical energy into useable electrical energy at the nanoscale scale [ 18 ]. As a result, piezoelectric energy harvesters also provide flexibility, superior biocompatibility, compact size, high electrical output, and universal adaptability.…”

Flexible electronics have great potential in the application of wearable and implantable devices. Through suitable chemical alteration, hydrogels, which are three-dimensional polymeric networks, demonstrate amazing stretchability and flexibility. Hydrogel-based electronics have been widely used in wearable sensing devices because of their biomimetic structure, biocompatibility, and stimuli-responsive electrical properties. Recently, hydrogel-based piezoelectric devices have attracted intensive attention because of the combination of their unique piezoelectric performance and conductive hydrogel configuration. This mini review is to give a summary of this exciting topic with a new insight into the design and strategy of hydrogel-based piezoelectric devices. We first briefly review the representative synthesis methods and strategies of hydrogels. Subsequently, this review provides several promising biomedical applications, such as bio-signal sensing, energy harvesting, wound healing, and ultrasonic stimulation. In the end, we also provide a personal perspective on the future strategies and address the remaining challenges on hydrogel-based piezoelectric electronics.
