“…In contrast to the above‐mentioned subtractive technologies, additive manufacturing techniques (inkjet, screen, and 3D printing) offer extremely low cost, completely digital, and highly scalable manufacturing processes . Due to these advantages, additive manufacturing techniques have been used to realize sensors, transistors, RF inductors, RF capacitors, RF filters, RF identification (RFID) tags, and so on. There have only been a few reports on printed RF switches .…”

be reconfigured to cover them, substantial space and cost savings could be achieved.(2) The wireless standards (frequency bands of operation) vary slightly in different parts of the world. In order to have a global device that can be adjusted to varying wireless standards in different parts of the world, the RF components need to be tuned to these frequency bands. Clearly, tunable or reconfigurable RF components are in demand. This tuning is typically done through an RF switch, which is capable of blocking or allowing RF signals to pass through it based on applied stimuli.Several kinds of technologies are used for RF-switching applications, such as a PIN diode-based switch, [1,2] a microelectromechanical-systems (MEMS)-based switch, [3,4] a transistor-based switch, [5,6] ferrite-and ferro-electric-based devices, [7,8] and so on. Each has its advantages and disadvantages; for instance, PIN diode switches feature fast switching speeds and longer operation life, but they can handle only relatively low power, and also they cannot work at very low frequencies.

“…When implemented through inks based on micro-and nanostructures (nanomembranes, nanoribbons, platelets, nanowires or quantum dots), printing techniques provide a simple, yet powerful pathway for the fabrication of device or system configurations that cannot be accomplished over any other method ( Table 5) 132 . Flexible and low-cost low-pass filters (first and second order) with adjustable cut-off frequency (ranging from 82 Hz to 740 Hz ) were printed through inkjet printing 142 . The low-pass filters were optimized and an adaptable cut-off frequency was achieved by an inkjet-printed organic thin-film transistor, allowing signal filtering in applications such as tactile sensing.…”

Smart and functional materials processed by printing technologies reveal an increasing interest due to small cost assembly, easy integration into devices and the possibility to obtain multifunctional materials over flexible and large areas. After introducing smart materials, printing technologies and inks, this review discusses the materials that are already being printed, mainly piezoelectric, piezoresistive, magnetostrictive, shape memory polymers (SMP), pH sensitive and chromic system materials. Since polymer-based smart materials are particularly attractive for device implementation, this review will focus on printed polymer-based smart materials. Finally, critical challenges and future research directions will be addressed.

“…The low-pass filters allow low-frequency components to pass and prevent high-frequency signals. 39 The filtering mechanisms depend on the impedance of devices. For any frequency signal, the resistance is constant, but the capacitance is related to the input signal frequency.…”

A graphene-based flexible filter was obtained via one-step laser heating of a polyimide film. The key parameters of a laser have been confirmed by comparing simulated results and experimental data. High-frequency components of input signals were filtered out effectively for different waveforms, such as sine, rectangular, triangle and pulse waveforms. In order to study filtering performance, this paper focused on amplitude frequency curve, phase frequency curve, transient response and mechanical stability. The phase frequency curve is linear distribution, indicating that it is convenient to control phase shift. The mechanical stability of the device remains good even after 5000 bends, which is unreported in previous work. This paper demonstrated that a graphene-based flexible filter prepared by one-step laser heating has excellent performance and opens new way of thinking about flexible electronics in the future.
