“…[196,197] Recently, scientists focused on NBT-based material electrospinning for specific applications, such as transducers [170] , micro-electro-mechanical systems (MEMS) [31,171,172] and nano-sensors. [173] Chen et al [31] have demonstrated that loading Ba 0.06 TiO 3 inside Na 0.5 Bi 0. was used to produce nanofibers with the high specific surface area. [173] By using bismuth nitrate, cerium nitrate, and titanium butoxide as resources, Jiang et al [174] have synthesized cerium-substituted bismuth titanate (BCT) nanofibers with a uniform diameter and good nanocrystalline distribution for energy harvesting application.…”

The field of nanotechnology has been gaining great success due to its potential in developing new generations of nanoscale materials with unprecedented properties and enhanced biological responses. This is particularly exciting using nanofibers, as their mechanical and topographic characteristics can approach those found in naturally occurring biological materials. Electrospinning is a key technique to manufacture ultrafine fibers and fiber meshes with multifunctional features, such as piezoelectricity, to be available on a smaller length scale, thus comparable to subcellular scale, which makes their use increasingly appealing for biomedical applications. These include biocompatible fiber-based devices as smart scaffolds, biosensors, energy harvesters and nanogenerators for the human body. This paper provides a comprehensive review of current studies focused on the fabrication of ultrafine polymeric and ceramic piezoelectric fibers specifically designed for, or with the potential to be translated toward, biomedical applications. It provides an applicative and technical overview of the biocompatible piezoelectric fibers, with actual and potential applications, an understanding of the electrospinning process, and the properties of nanostructured fibrous materials, including the available modeling approaches. Ultimately, this This article is protected by copyright. All rights reserved. 3 review aims at enabling a future vision on the impact of these nanomaterials as stimuli-responsive devices in the human body.

“…57 Moreover, in each case, the response time was lower than the recovery time because of the fact that the adsorption could be faster than the desorption of adsorbed water molecules. 58,59 The gure presents the repeatability curves for all the sensors, which signify their good sensing ability for humidity. The humidity sensing mechanism was based on a Grotthuss chain reaction.…”
