Special Issue Information

Dear Colleagues,

Passive Wireless sensors are a type of device that perform sensing and signal transmission when they are activated by external stimuli. Representative devices include piezoelectric resonators, LC resonators, surface acoustic wave resonators, etc. Self-Powered Wireless Sensors, on the other hand, are a class of devices and systems that can work without relying on an external power supply. They collect abundant waste energy from their surroundings, such as mechanical vibrations, walking, residual heat, microwave energy, etc. through electrostatic, piezoelectric, thermoelectric, triboelectric effects etc. These devices may provide either electrical signal output to form self-driven sensors or energy to form self-powered sensor systems. Passive Wireless and Self-Powered Wireless Sensors are the key components for state-of-art smart systems, and play an essential role in the modern information era, with widespread applications in intelligent manufacturing, smart homes and cities, smart medicine, etc. This Special Issue aims to provide an opportunity to address the aspects of simulation, design, materials, fabrication and applications of Passive Wireless and Self-Powered Wireless Sensor systems from both academic and industrial perspectives. Contributions that include novel sensor design, operation principles, energy collection, energy collection circuits and innovative sensors based on new concepts such as parity-time symmetry or coherent perfect absorption, etc., are particularly encouraged. Both review papers and original research articles are welcome.

The subject of the research contained in this paper is a new design solution for an energy harvesting system resulting from the combination of a quasi-zero-stiffness energy harvester and a two-stage flexible cantilever beam. Numerical tests were divided into two main parts-analysis of the dynamics of the system due to periodic, quasiperiodic, and chaotic solutions and the efficiency of energy generation. The results of numerical simulations were limited to zero initial conditions as they are the natural position of the static equilibrium. The article compares the energy efficiency for the selected range of the dimensionless excitation frequency. For this purpose, three cases of piezoelectric mounting were analyzed-only on the first stage of the beam, on the second and both stages. The analysis has been carried out with the use of diagrams showing difference of the effective values of the voltage induced on the piezoelectric electrodes. The results indicate that for effective energy harvesting, it is advisable to attach piezoelectric energy transducers to each step of the beam despite possible asynchronous vibrations. Full article

The key challenge for a lab-on-chip (LOC) device is the seamless integration of key elements of biosensing and actuation (e.g., biosampling or microfluidics), which are conventionally realised using different technologies. In this paper, we report a convenient and efficient LOC platform fabricated using an electrode patterned flexible printed circuit board (FPCB) pressed onto a piezoelectric film coated substrate, which can implement multiple functions of both acoustofluidics using surface acoustic waves (SAWs) and sensing functions using electromagnetic metamaterials, based on the same electrode on the FPCB. We explored the actuation capability of the integrated structure by pumping a sessile droplet using SAWs in the radio frequency range. We then investigated the hybrid sensing capability (including both physical and chemical ones) of the structure employing the concept of electromagnetic split-ring resonators (SRRs) in the microwave frequency range. The originality of this sensing work is based on the premise that the proposed structure contains three completely decoupled resonant frequencies for sensing applications and each resonance has been used as a separate physical or a chemical sensor. This feature compliments the acoustofluidic capability and is well-aligned with the goals set for a successful LOC device. Full article

In recent years, passive wireless sensors have been studied for various infrastructure sectors, making them a research and development focus. While substantial evidence already supports their viability, further effort is needed to understand their dependability and applicability. As a result, issues related to the theory and implementation of wireless sensors still need to be resolved. This paper aims to review and summarize the progress of the different materials used in different passive sensors, the current status of the passive wireless sensor readout devices, and the latest peripheral devices. It will also cover other related aspects such as the system equipment of passive wireless sensors and the nanogenerators for the energy harvesting for self-powered sensors for applications in contemporary life scenarios. At the same time, the challenges for future developments and applications of passive wireless are discussed. Full article

With the development of 5G, artificial intelligence, and the Internet of Things, diversified sensors (such as the signal acquisition module) have become more and more important in people’s daily life. According to the extensive use of various distributed wireless sensors, powering them has become a big problem. Among all the powering methods, the self-powered sensor system based on triboelectric nanogenerators (TENGs) has shown its superiority. This review focuses on four major application areas of wireless sensors based on TENG, including environmental monitoring, human monitoring, industrial production, and daily life. The perspectives and outlook of the future development of self-powered wireless sensors are discussed. Full article
