“…These phenomena further lead to the accumulation of printed a‐IGO precursor solution near the contact pads (ITO in our case) and unwanted thickening of the semiconductor film. [ 55 ] Consequently, in case of polyimide substrate, the diode performance, in terms of both DC and AC, decreases a little, when compared to the ones printed on the glass substrates. Figure 5b shows the frequency response of flexible HWR and DHWR circuits.…”

Printed electronic circuits are beginning to attract commercial success in different area of applications that include low‐cost wearables, biosensors, biomedical tags, packaging, e‐textiles etc. However, the major part of the research in this domain has always been focused at developing high performance thin film transistors (TFTs), while the other essential circuit elements, that are required, for example, for low‐loss conversion of the input power, have rarely been reported. In this regard, we demonstrate inkjet‐printed amorphous oxide based diodes on glass, and flexible polyimide substrates with rectification ratio >104 and operation frequency up to 25 MHz, and 15 MHz, respectively. Next, using the printed diodes full‐wave and double half‐wave rectifiers have been fabricated to convert input AC signals to DC supply. In addition, we demonstrate wireless power transfer (WPT), where the input AC signal has been wirelessly transmitted from a distance of 3 cm, at 125 kHz. The demonstrated WPT technology can be suitable for invasive implantable devices and stand‐alone systems in multiple mediums. Lastly, bending fatigue tests have been carried out with the printed diodes on flexible substrates, down to a bending radius of 2.5 mm to demonstrate tensile strain tolerance up to 2.5%.This article is protected by copyright.

“…While maximizing print resolution is challenging, it offers the highest benefits regarding data density. The maximum resolution achievable in inkjet printing primarily depends on factors like nozzle size, drop volume, the interaction of drops with the substrate, and ink spreading on the surface [33].…”

“…The solution to the increasing need for multiple copies of data and the storage of larger amounts of data was printing techniques. Inkjet printing has emerged as the most widely used form of printing and is undergoing continuous improvements in resolution [31], substrate compatibility [32], droplet control and precision [33], 3D printing [34], and overall print quality.…”

Handling and storing the immense amounts of data native to the information age is a major challenge in terms of technological sustainability and energy demand. To date, tape storage remains the most widespread method for data archiving, while DNA data storage appears to offer the best data density and long-term stability in the future. However, DNA data storage is still in its infancy primarily due to economic and accessibility challenges. This emphasizes the need for more practical and readily available alternatives.We present a method for data storage utilizing inkjet printable quantum dots on paper with photoluminescence (PL) readout. Our proof of principle study showcases the ability to print and stack multiple bits of data on a single spot by exploiting the unique PL properties of quantum dots. This approach utilizes easily accessible resources, including a consumer-grade printer and paper as the substrate. Additionally, we perform initial stability tests, investigate scalability by controlling emission intensity, and evaluate the potential data density achievable by our approach.

“…This printer consists of several injector nozzles in the printhead, and droplets are ejected in parallel to each other with each pulse. Subcategories of drop-on-demand inkjet are defined by the mode used to generate pulses, including acoustic, electrostatic, thermal, and piezoelectric methods. , The success of inject printing depends on the rheological properties of the ink, assessed by the ink’s Z parameter, defined as the inverse of the Ohnesorge number (Oh), further expressed in terms of the Weber number (We) and Reynolds number (Re). Numerical computations widely accept the optimum range for printing a stable droplet to be 1 < Z < 10 .…”

The human body continuously emits physiological and psychological information from head to toe. Wearable electronics capable of noninvasively and accurately digitizing this information without compromising user comfort or mobility have the potential to revolutionize telemedicine, mobile health, and both human−machine or human−metaverse interactions. However, state-of-the-art wearable electronics face limitations regarding wearability and functionality due to the mechanical incompatibility between conventional rigid, planar electronics and soft, curvy human skin surfaces. E-Tattoos, a unique type of wearable electronics, are defined by their ultrathin and skin-soft characteristics, which enable noninvasive and comfortable lamination on human skin surfaces without causing obstruction or even mechanical perception. This review article offers an exhaustive exploration of e-tattoos, accounting for their materials, structures, manufacturing processes, properties, functionalities, applications, and remaining challenges. We begin by summarizing the properties of human skin and their effects on signal transmission across the e-tattoo-skin interface. Following this is a discussion of the materials, structural designs, manufacturing, and skin attachment processes of e-tattoos. We classify e-tattoo functionalities into electrical, mechanical, optical, thermal, and chemical sensing, as well as wound healing and other treatments. After discussing energy harvesting and storage capabilities, we outline strategies for the system integration of wireless e-tattoos. In the end, we offer personal perspectives on the remaining challenges and future opportunities in the field.
