An over-the-distance wireless battery charger based on RF energy harvesting
2017
An RF powered receiver silicon IC (integrated circuit) for RF energy harvesting is presented as wireless battery charger. This includes an RF-to-DC energy converter specifically designed with a sensitivity of -18.8 dBm and an energy conversion efficiency of â¼45% at 900 MHz with a transmitting power of 0.5 W in free space. Experimental results concerned with remotely battery charging using a complete prototype working in realistic scenarios will be shown.
Internet of Things with Deep Learning-Based Face Recognition Approach for Authentication in Control Medical Systems
2022
Internet of Things (IoT) with deep learning (DL) is drastically growing and plays a significant role in many applications, including medical and healthcare systems. It can help users in this field get an advantage in terms of enhanced touchless authentication, especially in spreading infectious diseases like coronavirus disease 2019 (COVID-19). Even though there is a number of available security systems, they suffer from one or more of issues, such as identity fraud, loss of keys and passwords, or spreading diseases through touch authentication tools. To overcome these issues, IoT-based intelligent control medical authentication systems using DL models are proposed to enhance the security f…
Predictive pumping based on sensor data and weather forecast
2019
In energy production, peat extraction has a significant role in Finland. However, protection of nature has become more and more important globally. How do we solve this conflict of interests respecting both views? In peat production, one important phase is to drain peat bog so that peat production becomes available. This means that we have control over how we can lead water away from peat bog to nature without water contamination with solid and other harmful substances. In this paper we describe a novel method how fouling of water bodies from peat bog can be controlled more efficiently by using weather forecast to predict rainfall and thus, minimize the effluents to nature. peerReviewed
Explaining organizational adoption of technology : the case of cloud platforms
2015
The internet of things (IOT) is a vision that represents a world of connected devices which are identifiable and may have capabilities to sense and act on the surrounding environment. Almost every item in the planet has the potential to become part of the IOT. The data exchange between these devices requires that cloud technologies are applied. These cloud computing platforms already exist and need to adapt to the specific needs of the IOT in order to cope with the high demands of the IOT, for example handling the Big Data generated by the IOT devices. Nonetheless, little is known about the adoption levels of these platforms. In the past the UTAUT2 has been used to help explain technology a…
Internet of Things – Emergence of standards
2012
Poikolainen, Janne Internet of Things – Emergence of standards Jyväskylä: University of Jyväskylä, 2012, 34 p. Information System Science, Bachelor's Thesis Supervisor: Mazhelis, Oleksiy Internet of Things is a paradigm referring to the pervasive presence of networked things and objects that are able to interact and cooperate with each other. This paradigm also suggests that in the future these objects also produce large amounts of data to the internet and other network applications. Predictions say that the amount of data produced by things proceeds human produced data in the near future. These visions are grounded in the assumption that the advances in microelectronics, communications and…
Next Generation Home Sharing: Disrupting Platform Organizations with Blockchain Technology and the Internet of Things?
2020
During the last decade, the sharing economy has given birth to a number of market mediators, which have grown to become the world’s most valuable companies. Centralized sharing platforms like Uber, Didi Chuxing, and Airbnb have transformed several traditional industries. However, with the rise of the blockchain technology, some voices predict that these platform companies will soon be at risk of being disrupted themselves. In this chapter, we address the question of whether blockchain technology has given birth to a new breed of sharing economy platforms that can challenge the incumbents’ business models. We identify five different stages of the application of blockchain technology in emerg…
New tree monitoring systems: from Industry 4.0 to Nature 4.0
2019
This is the accepted version of the article "New tree monitoring systems: from Industry 4.0 to Nature 4.0" published as final paper in Annals of Silvicultural Research Volume 43, Issue 2, 2019, Pages 84-88, http://dx.doi.org/10.12899/asr-1847 Abstract - Recently, Internet of Things (IoT) technologies have grown rapidly and represent now a unique opportunity to improve our environmental monitoring capabilities at extremely low costs. IoT is a new system of thinking in which objects, animals or people are equipped with unique identifiers and transfer data to a network without requiring human-to-human or human-to-computer interaction. IoT has evolved from the convergence of wirele…
Model-Driven Development Approach for Providing Smart Home Services
2009
Smart home is about the application of automation techniques for the comfort and security of residents' privately owned homes. In a smart home environment, different and independent embedded devices provide services that can be freely used by others, in the sense of service invocation. This paper presents our idea of using Model Driven Development (MDD) for the composition of existing services, by which we aim at demonstrating how new smart home services will be promoted.
A Battery-Free Smart Sensor Powered with RF Energy
2018
The development of Internet of Things (IoT) infrastructure and applications is stimulating advanced and innovative ideas and solutions, some of which are pushing the limits of state-of-the-art technology. The increasing demand for Wireless Sensor Network (WSN) that must be capable of collecting and sharing data wirelessly while often positioned in places hard to reach and service, motivates engineers to look for innovative energy harvesting and wireless power transfer solutions to implement battery-free sensor nodes. Due to the pervasiveness of RF (Radio Frequency) energy, RF harvesting that can reach out-of-sight places could be a key technology to wirelessly power IoT sensor devices, whic…
Low-Power Wide-Area Networks for Sustainable IoT
2019
Low-power wide-area (LPWA) networks are attracting extensive attention because of their abilities to offer low-cost and massive connectivity to Internet of Things (IoT) devices distributed over wide geographical areas. This article provides a brief overview on the existing LPWA technologies and useful insights to aid the large-scale deployment of LPWA networks. Particularly, we first review the currently competing candidates of LPWA networks, such as narrowband IoT (NB-IoT) and long range (LoRa), in terms of technical fundamentals and large-scale deployment potential. Then we present two implementation examples on LPWA networks. By analyzing the field-test results, we identify several chall…
