Ferroelectrics for Biomedical Applications
نویسندگان
چکیده
Currently, researchers are mainly focusing the phase transitions, domain structures, domain wall functionalities, magneto electric coupling, and the potential applications in high-density ferroelectric non-volatile memories of ferroelectric materials [1-5]. However, there are relatively less research interests in the biomedical applications of ferroelectric materials which is very important to human life, such as the lead zirconate titanate (PZT) ceramics used in ultrasonic transducers for medical ultrasound systems and ferroelectric thin film capacitors implanted to the body as energy storage supply power for medical micro-devices. In this mini-review, we will introduce the biomedical applications of ferroelectric ceramics, ferroelectric thin films and ferroelectric polymers.

Comparison of Paraelectric and Ferroelectric Materials for Applications as Dielectrics in Thin Film Integrated Capacitors
Ferroelectrics such as BaTiO3, PbxZr1-xTiO3 and BaxSr1-xTiO3 can exhibit dielectric constants up to three orders of magnitude higher than those of paraelectric materials such as SiO2, Al2O3, Ta2O5, and BCB. However, the dielectric properties of ferroelectrics are typically a stronger function of temperature, frequency, film thickness, and bias resulting in significant nonlinearities in their pe...
