Physically soft magnetic films and devices: fabrication, properties, printability, and applications

Abstract

Developing materials that enable fabricating multifunctional devices has been the cornerstone of present-day materials science and engineering. Such multi-functionality makes these devices capable of novel applications ranging from energy, storage,...

A PDMS pocket based transparent polydopamine-decorated polypyrrole nanofibril–polyacrylamide hydrogel for EMI shielding applications

“…[4][5][6][7][8] Due to their potential uses in a variety of industries, including artificial skins, supercapacitors, and sensors, the creation of hydrogel-based EMI shielding materials having new features is emerging as an alternative. [9][10][11][12] With a high water-holding capacity, hydrogels are soft materials made of three-dimensional polymer networks that have been crosslinked chemically or physically. 13 Because of their high water-holding capacity, they can be used in numerous industries, including tissue engineering, wastewater treatment, and controlled drug release.…”

Fabrication of a magnetic thin-film actuator using roll-to-roll gravure printing

“…Thin films of soft magnetic actuators made from a mixture of elastomers and magnetic particles (MPs) have been extensively researched in recent years. 1,2) These magnetic actuators have a wide range of applications such as micro and millimeter-scale grippers of soft robots, [3][4][5] drug delivery devices, 6) cilia-based mixing devices, 7,8) and microfluidic pumps. 9) Electrostatic and electronic types of actuators need tethers to conduct electric charges.…”
