“…The demonstration indicated the promising potential in wearable applications and human-machine interfaces. In addition to resonators, stretchable antennas were explored for strain sensing applications as well, including stretchable patch antenna, [217] CPW monopole antenna made from printed Ag NWs, [236] and fluidic dipole antenna based on liquid metal. [188] By detecting the change of resonant frequency and/or gain of the stretchable antennas, strain induced in the antenna can be determined by the sensors.…”

“…Screen printing is advantageous when compared to other printing systems as it is more versatile, and processing is simple, capable of reproducing similar structures in large batches with minimum dimensional variations. Results are duplicated by repeating the similar printing parameters and optimized solution pastes [12,39].…”

“…The prominent challenges in printed electronics are material compatibility, substrate surface energy, viscosity of the materials' solution, and compatibility of dissimilar materials in multilayer structure, technology limitations in terms of film thickness, width, and height. As compared to conventional electronic manufacturing, printing technologies are revolutionizing the incredible field of flexible/bendable electronics by providing cost-effective routes for processing diverse electronic materials on nonplanar substrates at compatible temperatures [9][10][11][12]. Simplified processing steps, reduced materials' wastage, low-fabrication costs, and simple patterning techniques make printing technologies very attractive when compared to standard microfabrication in clean room processes.…”

Fabrication of electronic devices on different flexible substrates is an area of significant interest due to low cost, ease of fabrication, and manufacturing at ambient conditions over large areas. Over the time, a number of printing technologies have been developed to fabricate a wide range of electronic devices on nonconventional substrates according to the targeted applications. As an increasing interest of electronic industry in printed electronics, further expansion of printed technologies is expected in near future to meet the challenges of the field in terms of scalability, yield, and diversity and biocompatibility. This chapter presents a comprehensive review of various printing electronic technologies commonly used in the fabrication of electronic devices, circuits, and systems. The different printing techniques based on contact/noncontact approach of the printing tools with the target substrates have been explored. These techniques are assessed on the basis of ease of operation, printing resolutions, processability of materials, and ease of optimization of printed structures. The various technical challenges in printing techniques, their solutions with possible alternatives, and the potential research directions are highlighted. The latest developments in assembling various printing tools for enabling high speed and batch manufacturing through roll-to-roll systems are also explored.

Investigating the dynamic behaviour of circular plate resting on elastic foundations are very important in designing of structural systems. This study examines the free vibration analysis of circular plate resting on Winkler and Pasternak foundations. The governing nonlinear partial differential equation is transformed to Duffing equation based on von Kármán geometric nonlinear principle and the nonlinear to linear frequency ratios are obtained while the linear natural frequencies are determined using Galerkin of weighted residual method. Also, the accuracy and reliability of the approximate solutions obtained are demonstrated by comparing the obtained results with available results reported in the literature. The analytical solutions obtained are used for examining the effect of elastic foundations on the dynamic behaviour of the circular plate. From the results, it is observed that, increasing elastic foundation parameter increases the natural frequency. As the nonlinear foundation increases, the nonlinear vibration frequency ratio decreases. The nonlinear Winkler foundation attenuates the amplitude of vibration of the circular plate. It is hoped that, the present study will contribute to the existing knowledge of classical theory of vibration.
