“…Integrating sensors in smart city's infrastructure [1][2] and transportation routes for health monitoring [3], harvesting the environmental energy [4] [5] or equipped with powerful batteries for reliability such as for road traffic monitoring [6] or parking occupancy [7] upgrade previous technology and connects it to the new wave of internet of things (IoT) [8]. In the energy system, embedding sensors inside the rechargeable batteries used for e-mobility, to increase battery's life [9] decrease charging time [10] and reduce thermal runaway through in-situ monitoring [11] proved to be an efficient progressive measure. In addition, embedded communications on power lines like for electric cars [12] with a minimum of interfacing for wireless [13] or wired [14] transceivers since the DC power line shows no impact on its overall impedance [15] [16] constitutes another level of fusion and integration.…”

Wide bandgap Gallium Nitride (GaN) technology promises to deliver the next generation of power transistors capable of high energy density and compact design integration however, without active monitoring high failing rates are recorded due to its instability to design parameter variations. Moreover, the electromagnetic (EM) radiofrequency (RF) emissions due to GaN power switching require extra design resources. Considering the extensive research area dedicated to galvanic isolated magnetic sensors for GaN wafer monolithic integration with usage in power monitoring, this study investigates the conditions that a Hall sensor is required to meet when operating in close proximity of a GaN transistor. Through considerable experimental testing, it was determined that the sensor requires a magnetic field starting from ±1 mT when interfaced with a microcontroller. Additionally, since the GaN transistor's EM RF switching noise was one of the most monitored parameters during the experiments, it was discovered that it is proportional to the transistor's current transfer area whereas its magnitude is due to electrical current required by the load. As a result of these findings, the EM radiated switching noise may apply to all electrical switches and provide a significant advantage when designing for EM compatibility (EMC).

“…This way, by using modern multi-frequency wireless modules designed for smart electronics and inter-vehicle communication [ 20 , 21 , 22 ], future addition of road nodes and alternative data protocols bridging different networks together may be available. Despite the fact that road studs without rechargeable capabilities use rechargeable battery packs due to their high energy density, such as Li-ion technology, this energy storage technology can be improved furthermore by using battery cell internal instrumentation [ 23 , 24 ] specifically designed for automotive and off-grid energy storage applications. The newly developed IoT and 5G network [ 25 ] may be adjusted to cover data links for the remote road studs while, in parallel, providing real-time information to the moving vehicles.…”

Updating the road infrastructure requires the potential mass adoption of the road studs currently used in car detection, speed monitoring, and path marking. Road studs commonly include RF transceivers connecting the buried sensors to an offsite base station for centralized data management. Since traffic monitoring experiments through buried sensors are resource expensive and difficult, the literature detailing it is insufficient and inaccessible due to various strategic reasons. Moreover, as the main RF frequencies adopted for stud communication are either 868/915 MHz or 2.4 GHz, the radio coverage differs, and it is not readily predictable due to the low-power communication in the near proximity of the ground. This work delivers a reference study on low-power RF communication ranging for the two above frequencies up to 60 m. The experimental setup employs successive measurements and repositioning of a base station at three different heights of 0.5, 1 and 1.5 m, and is accompanied by an extensive theoretical analysis of propagation, including line of sight, diffraction, and wall reflection. Enhancing the tutorial value of this work, a correlation analysis using Pearson’s coefficient and root mean square error is performed between the field test and simulation results.
