Integrating electronic applications with paper, placed next to or below printed images or graphics, can further expand the possible uses of paper substrates. Consuming paper as a substrate in the field of electronics can lead to significant innovations toward papertronics applications as paper comprises various advantages like being disposable, inexpensive, biodegradable, easy to handle, simple to use, and easily available. All of these advantages will definitely spur the advancement of the electronics field, but unfortunately, putting electronics on paper is not an easy task because, compared to plastics, the paper surface is not just rough but also porous. For example, in the case of lateral flow assay testing the sensor response is delayed if the pore size of the paper is enormous. This might be a disadvantage for most electrical devices printed directly on paper. Still, some methods make it compatible when fit with a rough, absorbent surface of the paper. Building electronic devices on a standard paper substrate have sparked much interest because of its lightweight, environmental friendliness, minimal cost, and simple fabrication. A slew of improvements have been achieved in recent years to make paper electronics perform better in various applications, including transistors, batteries, and displays. In addition, flexible electronics have gained much interest in human−machine interaction and wireless sensing. This review briefly examines the origins and fabrication of paper electronics and then moves on to applications and exciting possible paths for paper-based electronics.

Ultraviolet-induced photochromism has been an attractive dual-mode security encoding approach to enhance the anticounterfeiting performance of commercial products. However, photochromic inks have recently reported major drawbacks, including high cost, low efficacy, and poor durability. Herein, we report the development of self-healing security ink using poly(2-acrylamido-2-methyl-1-propanesulfonic acid) (PAMPS) immobilized with rare-earth-activated aluminate nanoparticles for advanced anticounterfeiting applications. Remarkably, self-healable security inks can ensure durability and photostability. The self-healing composite ink demonstrated ultraviolet-induced photochromism with high reversibility and photostability. Various self-healing composite inks of diverse emission properties were developed using various concentrations of rare-earth-activated aluminate nanoparticles. Homogeneous films were printed onto paper sheets, demonstrating a colorless appearance that changed to green under ultraviolet rays as proved by the CIE Lab. The morphological properties of the phosphor were examined, demonstrating a particle diameter of 4–9 nm. Various analytical methods were used to investigate the morphology and chemical composition of the prepared photochromic films. Both the rheological and mechanical properties of the ink solution and the ink-printed paper sheets were measured. The luminescent films had an excitation wavelength of 365 nm (colorless) and an emission peak at 520 nm (green). Various industries can benefit greatly from the current smart ink as an efficient strategy for the development of anticounterfeiting commercial products.

“…The thermochromic polymer nanoparticle ink is often capable to show excellent optical properties because of their minimal light reflection and high-surface area. However, these polymer nanoparticles often clump together, causing printer nozzles to get clogged and a major conflict to arise . Therefore, it is possible to describe the creation of thermochromic nanoparticles dispersed in a polymer matrix as a cutting-edge technique for better secure authentication.…”

Temperature-driven colorful switching inks have been an interesting security encoding method to improve the anticounterfeiting properties of commercially available merchandise. Recently, thermochromic inks have faced many disadvantages, such as low efficiency, high cost, and low durability. In the current study, we developed self-healable ink from poly(2-acrylamido-2-methyl-1-propanesulfonic acid) (PAMPSA) integrated with the anthocyanidin(ACY)-based red-cabbage extract in the presence of ferrous sulfate for authentication purposes. Self-healable inks have been able to guarantee durability and thermal stability. Environmentally friendly, ACY-based chromophore was extracted from Brassica oleracea L. var. Capitata (red-cabbage) to serve as a spectroscopic probe immobilized into PAMPSA. The prepared self-healable nanocomposite ink (PAMPSA-ACY) displayed temperature-induced chromism with high reversibility and thermal stability. Different self-healable nanocomposite inks of thermochromic features were prepared employing different ratios of the ACY-based red-cabbage extract. As described by Commission Internationale de L’éclairage Lab coordinates, homogeneous films were stamped on the paper surface to show a purple color (631 nm) able to switch color into red (458 nm) with the increase in temperature from 25 to 65 °C, respectively. Transmission electron microscopy, infrared spectra (FT-IR), energy-dispersive X-ray, and scanning electron microscopy were utilized to inspect the morphological behavior and chemical compositions of thermochromic prints. Both mechanical and rheological properties of ink-printed paper substrates and ink solution were also investigated. Both of antimicrobial activity and cytotoxicity study of the nanocomposite ink (PAMPSA-ACY) were also evaluated. Various industries can take the advantage of the current ink as a competent approach for anticounterfeiting purposes.
