Biocompatible Nanogenerators through High Piezoelectric Coefficient 0.5Ba(Zr_0.2Ti_0.8)O₃‐0.5(Ba_0.7Ca_0.3)TiO₃ Nanowires for In‐Vivo Applications

Abstract

Lead-free BZT-BCT (0.5Ba(Zr0.2Ti0.8)O3-0.5(Ba0.7Ca0.3)TiO3) nanowires with a high piezoelectric coefficient are synthesized and nanogenerators (NGs) composed of them are successfully developed. The studied in vitro and in vivo biocompatibility of the NGs shows great potential for their application as in vivo power sources.

Wireless, power-free and implantable nanosystem for resistance-based biodetection

“…[19] sandwiched by two glass substrates coated with Ag electrodes and a PDMS layer mixed with iron powder attached on the top of the device. When putting the device in an inhomogeneous magnetic field, the film with iron powder squeezes the device, and the film with BZT-BCT NWs converts mechanical energy into electronic energy.…”

Silk fibroin-based biodegradable piezoelectric composite nanogenerators using lead-free ferroelectric nanoparticles

“…Since ZnO nanowire arrays have been used to fabricate such piezoelectric nanogenerators [1][2][3][4][5][6], there have been many attempts to fabricate piezoelectric energy harvesting devices by employing various nanostructured materials such as ZnO [7], BaTiO 3 [8], KNbO 3 [9], xKNaNbO 3 -(1-x)LiNbO 3 (KNLN) [10], ZnSnO 3 [11], and NaNbO 3 [12] and 0.5Ba(Zr 0.2 Ti 0.8 )O 3 -0.5 (Ba 0.7 Ca 0.3 )TiO 3 (BZT-BCT) [13]. Recently, the polymer-moldsupporting nanogenerators composed of nanowires and nanoparticles have been successfully demonstrated as one of promising platforms for the large-scale and super-flexible nanogenerators.…”
