“…According to a recent study, it is projected that the number of interconnected devices will grow in the coming years, reaching 50 billion by the year 2030 [2][3][4], many of which are constantly connected due to the growing use of the Internet of Things (IoT) concept [5,6]. This trend has been fueled by the development of micro and nano devices, which can serve as actuator designs or data transfer devices and can be installed ubiquitously due to their small size [7][8][9].…”

Owing to the escalating adoption of IoT systems across various domains, the demand for mobile and wireless power sources has surged. Although conventional batteries typically serve as energy storage components, the current low-power consumption devices necessitate eco-friendly alterna-tives. In this study, we designed, fabricated, and characterized an energy harvesting device that repurposes mechanical vibrations. A three-beam design was employed to harvest energy across a broader range of potential frequencies. Finite element models were simulated to ascertain the first bending moment for both sets of beams. A nanostructured piezoelectric multilayer film made of ZnO was deposited onto an AISI 304 steel substrate, and a photosensitive resin seismic mass was implemented. Low-cost techniques generating minimal environmental waste were leveraged in the fabrication process. The piezoelectric film was deposited using a spray nebulization technique involving recycled materials and cost-effective equipment. Micrographs of the layers unveiled the presence of nanospheres with diameters of 250 nm. Employing a custom-made shaker, output voltages of 1.08 V and 180 mV, and power outputs of 1.849 µW and 16.2 nW were achieved for each set of beams. The electrical characterization was conducted using a custom-made shaker, repurposing materials for this objective.

“…Nowadays, Wireless Fidelity (Wi-Fi) networks are becoming increasingly popular as they offer mobility, enhanced quality of service and are relatively easy to deploy. Together with the new generation of mobile communication standards, the Wi-Fi technology pave the way towards Internet of Things (IoT) applications [1]. With the advent of IoT, the antenna becomes a decisive element which has an essential role in defining the overall performance of the system.…”

This article presents a practical approach towards the use of reflectors for Wi-Fi antennas. First, a custom Wi-Fi antenna was simulated in CST Studio software. Using simulation, we have analysed the effects of several types of reflectors on the antenna parameters. The most effective solution (antenna plus corner reflector) was manufactured and mounted on the specially designed ensemble. The designed ensemble enables automatic rotation of the reflector around the antenna. Simulation results were finally confronted with experimental measurements to validate the data. Our findings show that the presence of the reflector significantly increases the gain in the main radiation lobe and several other radiating directions.
