Skinlike Disposable Tattoo on Elastic Rubber Adhesive with Silver Particles Penetrated Electrode for Multipurpose Applications

Abstract

We propose a silver precursor with in situ reduction under an adhesive substrate with a silver precursor penetration effect. It shows a high durability under mechanical deformation resulting from the composite form of the Ag-penetrated electrode adhesive. This stretchable electrode in which the silver particles are tightly penetrated into the adhesive with a confining effect can be used for various purposes since it offers water-proof properties and a high mechanical stability up to 70% strain, radius of curvature 0.5 mm ( R/ R< 1.5), and electrical resistance of 0.58 ± 0.063 kΩ □ by adhering to the multipurpose application.

Chitin Nanocrystals as an Eco-friendly and Strong Anisotropic Adhesive

“…With the development of industrialization, a variety of high-performance adhesives have been synthesized. At present, new adhesives have been developed with UV or visual light curing properties, including thermoplastic, rubber, and pressure-sensitive materials. − These artificial adhesives usually have high adhesion and strength, but they are not resistant to high temperature. For example, the adhesion provides by commercial 502 cyanoacrylate glue will fail at 150 °C.…”

Vertically and Horizontally Drawing Formation of Graphite Pencil Electrodes on Paper by Frictional Sliding for a Disposable and Foldable Electronic Device

“…Recent studies on paper electronics have reported the use of light and flexible paper as a substrate to manufacture various devices and electrodes. − Paper is made of cellulose fibers with variable spacing based on the type and structure of cellulose, resulting in varying permeability and flexibility. The paper substrates are made into electrodes by various methods that do not require a high-temperature process, as follows: ink-jet printing by a drop-on-demand method to drop microdroplets, , microfluidic devices, − electrohydrodynamic technology using solution conductors, − screen printing using conductive ink such as carbon nanotube (CNT) or silver nanowire, − and direct pen writing, which forms an electrode by drawing on a paper with a pencil directly. − Thus, the electrodes formed can be used as application devices, such as flexible displays, − touchscreens, and supercapacitors. − In addition, it is advantageous to manufacture environmentally friendly disposable devices for one time use because compared with other materials, it is a low-cost and biodegradable invention. ,− The direct pencil writing by hand processing is advantageous in that the electrode is formed by simply drawing with a graphite pencil on paper, which is the simplest, cost-effective, and disposable method. , Paper is produced from raw wood pulp softened with chemicals followed by separation of fibers from the pulp by mechanical actions that are energy intensive . The torn fibers are transformed into various types of papers via refining and filling processes .…”
