Perspectives on recent advancements in energy harvesting, sensing and bio-medical applications of piezoelectric gels

Abstract

This review highlights the recent progress in piezoelectric gels (also known as PiezoGels) comprised of polymers, ceramic oxides and supramolecular piezoelectric materials used for energy harvesting, sensing and wound dressing.

Low-dimensional nanostructures for monolithic 3D-integrated flexible and stretchable electronics

“…Recently, flexible piezoelectric sensors based on piezo-fibers and piezoelectric gels have also been reported. 196 The triboelectric effect is a mechanism that converts mechanical energy into electrical energy, effectively generating triboelectric charges between two materials in contact through the coupling of contact electrification and electrostatic induction. 197…”

Advances in magnetoelectric composites for promoting bone regeneration: a review

“…These reactive radicals have a wide range of applications and strong oxidizing properties, and can be used in areas such as degradation of dye solutions, decomposition of water to produce hydrogen, sterilization, and tumor cell destruction. 48 The magnetoelectric effect has been combined with the electrochemical effect. Coupling the magnetoelectric effect with electrochemical reactions can also produce magnetic field-induced catalytic effects.…”

An Emerging Era: Conformable Ultrasound Electronics

“…Different from PLLA, chitosan is another biomaterial that can be processed into a very thin and highly compliant flexible film for flexible MEMS and miniaturized devices. [141] Additional investigations have been conducted on several organic piezoelectric gels [142] and piezoelectric biomaterials [143] (i.e., glycine, cellulose, collagen, and silk) to explore their potential use as piezoelectric devices. However, there is currently no available literature reporting their utilization as ultrasound transducers.…”
