“…The idea on which the proposed IoE paradigm revolves is the exploitation of the wireless-based ecosystem, where some existing devices (hereinafter referred to as trackers) are used in order to track the activity of other devices associated to people or things (hereinafter referred to as entities), registering a series of immutable information about the latter ones by using the features offered by a blockchain-based distributed ledger. This idea relies on what affirmed by several authoritative studies, which indicate that by the end of this decade the number of smart-phones and tablets will be about 7.3 billion of units [53], as well as the number of IoT devices, which will be between 20 and 50 billion by 2020 [56].…”

The exponential growth of wireless-based solutions, such as those related to the mobile smart devices (e.g., smart-phones and tablets) and Internet of Things (IoT) devices, has lead to countless advantages in every area of our society. Such a scenario has transformed the world a few decades back, dominated by latency, into a new world based on an efficient real-time interaction paradigm. Recently, cryptocurrency have contributed to this technological revolution, the fulcrum of which are a decentralization model and a certification function offered by the socalled blockchain infrastructure, which make it possible to certify the financial transactions, anonymously. However, it should be observed how this challenging scenario has generated new security problems directly related to the involved new technologies (e.g., e-commerce frauds, mobile bot-net attacks, blockchain DoS attacks, cryptocurrency scams, etc.). In this context, we can acknowledge that the scientific community efforts are usually oriented toward specific solutions, instead to exploit all the available technologies, synergistically, in order to define more efficient security paradigms. This paper aims to indicate a possible approach able to improve the security of people and things by introducing a novel blockchain-based distributed paradigm to security defined Internet of Entities (IoE). It represents an effective mechanism for the localization of people and things, which exploits both the huge number of existing wireless-based devices and the blockchain-based distributed ledger technology, overcoming the limits of traditional localization approaches, but without jeopardizing the user privacy. Its operation is based on two core elements with interchangeable roles, entities and trackers, which can be very common elements such as smart-phones, tablets, and IoT devices, and its implementation requires minimal efforts thanks to the existing infrastructures and devices. The possibility of including further information to those of localization, such as those generated by device sensors, gives rise to a novel and widely exploitable data environment, whose applications can be extended to contexts different from that of the localization of people and things, e.g., eHealth, Smart Cities, and so on.

“…Recent high-impact studies have highlighted the growing demand for sustainable and environmentally-friendly energy sources, driven by the proliferation of electronics and the Internet of Things (IoT). However, traditional fossil fuels and battery storage systems are no longer efficient enough to meet these demands [1,2]. Furthermore, the electronics requires self-powered systems due to the impracticality of frequent battery changes [3].…”

The growing demand for self-powered systems and the slow progress in energy storage devices have led to the emergence of piezoelectric materials as a promising solution for energy harvesting. This study aims to investigate the effects of chirality, length, and strain rate on the piezoelectric potential of BNNTs through molecular dynamics simulation. Accurate data and guidance are provided to explain the piezoelectricity of chiral nanotubes, as the piezoelectric potentials of these nanotubes have previously remained unclear. The present study focuses on calculating the effect of these parameters based on the atomic model. The observed results stem from the frequencies and internal deformations, as the axial frequencies and deformations exhibit more substantial modifications compared to transverse directions. The piezoelectricity was found to depend on chirality, with the order of BNNT piezoelectricity sufficiency being in the sequence of zigzag > chirality > armchair configurations. The length of the BNNTs was also found to influence piezoelectricity, while the strain rate had no effect. The results also indicate that BNNTs can generate power in the milliwatts range, which is adequate for low-power electronic devices and IoT applications. This research provides valuable insights into the piezoelectricity of chiral nanotubes and offers guidance for designing efficient energy harvesting devices.

“…Energy harvesters have been attracting much attention over the past decade that can convert ambient energy in the environment, such as mechanical vibrations, heat, fluid flows, electromagnetic radiation, radio waves and in vivo energies into electrical energy for low-power applications [ 8 ]. Energy harvesting is a sustainable power source which can be utilized in wireless sensor networks (WSNs), mobile electronics and implantable and wearable IoT devices, eliminating the need for network-based energy, conventional batteries, cables and minimizing maintenance and ecological costs [ 9 ]. In energy harvesting, various energy conversion mechanisms have been investigated such as piezoelectric [ 10 , 11 ], pyroelectric [ 12 ], photovoltaic [ 13 ], triboelectric [ 14 ] and magneto-mechano-electric [ 15 ].…”

In the ongoing fourth industrial revolution, the internet of things (IoT) will play a crucial role in collecting and analyzing information related to human healthcare, public safety, environmental monitoring and home/industrial automation. Even though conventional batteries are widely used to operate IoT devices as a power source, these batteries have a drawback of limited capacity, which impedes broad commercialization of the IoT. In this regard, piezoelectric energy harvesting technology has attracted a great deal of attention because piezoelectric materials can convert electricity from mechanical and vibrational movements in the ambient environment. In particular, piezoelectric-based flexible energy harvesters can precisely harvest tiny mechanical movements of muscles and internal organs from the human body to produce electricity. These inherent properties of flexible piezoelectric harvesters make it possible to eliminate conventional batteries for lifetime extension of implantable and wearable IoTs. This paper describes the progress of piezoelectric perovskite material-based flexible energy harvesters for self-powered IoT devices for biomedical/wearable electronics over the last decade.
