A Smart Energy Harvesting Platform for Wireless Sensor Network Applications

Abstract

Advances in micro-electro-mechanical systems (MEMS) as well as the solutions for power scavenging can now provide feasible alternatives in a variety of applications. Wireless sensor networks (WSN), which operate on rechargeable batteries, could be based on a fresh basis which aims both at environmental power collection and wireless charging in various shapes and scales. Consequently, a potential illimitable energy supply can override the hypothesis of the limited energy budget (which can also impact the system’s efficiency). The presented platform is able to efficiently power a low power IoT system with processing, sensing and wireless transmission potentials. It incorporates a cutting-edge energy management IC that enables exceptional energy harvesting, applicable on low power and downsized energy generators. In contrast to other schemes, it supports not only a range of power supply alternatives, but also a compound energy depository system. The objective of this paper is to describe the design of the system, the integrated intelligence and the power autonomy performance.

Cooperation between Roads and Vehicles: Field Validation of a Novel Infrastructure-Based Solution for All Road Users’ Safety

“…The core novelty of the solution lies in the custom on-road unit (ORU) developed in the project-the so-called "strip"-which was designed to fulfill three critical requirements: (1) low energy for sustainability for the ORU due to space limitations, (2) low height dimension (for the ORU form) and (3) robustness as the application concerns high criticality. The ORU consists of the following elements [15,16] all hosted and integrated on one single component:…”

“…A similar but simpler configuration of the strip has been also created and added to accommodate vulnerable road user (VRU) scenarios; in this case, the strip is installed on the road pavement area that precedes the zebra crossing and the sensorial part consists only of a corresponding detection system; this time of the pedestrians. 4) parts of the "strip" and a typical horizontal installation in the road lane; source [16].…”

An Impact Localization Solution Using Embedded Intelligence—Methodology and Experimental Verification via a Resource-Constrained IoT Device

“…We regard our paper as a significant work towards the broad use of WSNs in advanced IoT applications, as we aim to integrate effectively the characteristic resource-constrained nature of sensors into an industrial application characterized by strict real-time specifications (e.g., systems that are installed on the road surface, demonstrated in [ 10 ], and for infrastructure monitoring purposes [ 11 ], that also need sustainable SHM tools for the structure itself, to meet their autonomy requirements). Our approach targets several problems and needs in Industrial IoT applications such as the low-latency, real-time information exchange and decision-making, the concerns for security and privacy, the limited bandwidth for data sharing as well as the unreliable performance of the wireless channel into harsh production environments.…”

Ανάπτυξη προσαρμοστικών συστημάτων για εξοικονόμηση ενέργειας σε κτίρια με εφαρμογή τεχνολογιών διαδικτύου των αντικειμένων (IoT) και μεθοδολογιών πληθοπορισμού

“…Σε επίπεδο πρωτοκόλλων επικοινωνίας, αναπτύξαμε ένα ενεργειακά αποδοτικό multihop BLE πρωτόκολλο για κόμβους με περιορισμένους πόρους [13]. Σε επίπεδο υλικού, αναπτύξαμε μια έξυπνη πλακέτα για συλλογή και διαχείριση ενέργειας σε ΙοΤ συσκευές χαμηλής κατανάλωσης [14] [15]. Σε επόμενη εργασία μας [16], αναπτύχθηκε μια νέα πλακέτα η οποία ενσωματώνει επεξεργαστή και μετρητικές διατάξεις όπου μπορεί να γίνει πολύ καλύτερη διαχείριση της ενέργειας.…”
