“…This type of material is used for electronic devices such as transducers that are used for microspeakers or for medical ultrasound, sensors used for measuring changes in temperature, pressure, strain or force and for motorized actuators among other applications. One of the most utilized piezoelectric materials are lead zirconate titanates Pb(Zr x Ti 1−x )O 3 (PZT) and lanthanum modified lead zirconate titanate (Pb 1−3x/2 La x )(Zr y Ti 1−y )O 3 (PLZT) due to their increased functional dielectric and ferroelectric properties [1][2][3]. PZT-based thin films have been used in different areas such as sensors, cantilever actuators [4,5] and ultrasonic micromotors [6].…”

In this paper we report the development of thin films composed of two piezoelectric materials, namely (Ba(Ti0.8Zr0.2)O3-x(Ba0.7Ca0.3)TiO3 (BCTZ) and polyvinylidene difluoride (PVDF), thus obtaining high piezoelectric hybrid heterostructures for making them a viable option for wearable pressure sensors. The piezoelectric output response as a function of different weight percentage of BCTZ ceramic powders (x = 0.50 BCTZ50 and x = 0.55 BCTZ55) in the PVDF matrix was investigated. The highest value of the piezoelectric coefficient d33 and the capacitance, with low dielectric loss was obtained for the heterostructure composed of PVDF/BCTZ50.
