Increase the Efficiency of IoT Devices by Using the Wireless Power Transmission in the Industrial Revolution 4.0

Technology has impacted every field of life, and Education sector is no exception. It has seen seismic changes off-late. The traditional classroom teaching-learning process involved teachers and students using the black-board approach. But, the past years have seen a change in dynamics of this process. Technology has crept in and has profoundly changed it for better. On one hand, when traditional classrooms had teachers, students and books as players, the current classroom has teachers, students, robots, e-books, laptops and books as the players. Today’s classrooms have enabled the teaching-learning process cross boundaries in the form of e-lectures and tutorials. Massive amount of Information is readily available for the process. Also, a shift from “Teacher-centric” to “Student Centric” can be seen in the current scenario. Several technologies have been key-players in revolutionizing the education sector, but the focus of this paper is concentrated in exploiting the applications of Blockchain and IoT in the sector and identifying the areas where they prove to be beneficial. An extensive literature survey shall be done to understand, and identify how these technologies are a solution to major educational problems. The teaching learning process needs to be understood with respect to various parameters: change in process, change in players, change in outcomes derived, and others. The associated challenges shall also be identified. A detailed analysis of these enables us to conclude that these technologies, can revolutionize the education sector for better in future, particularly Blockchain is young, but, owing to the benefits derived from it, further research and adoption shall for surely change the teaching-learning process.

This research and development project aimed to create learning materials in the form of an Internet of Things (IoT) trainer kit specifically designed for the Digital Circuit course. The goal was to enhance student motivation and learning outcomes by facilitating a comprehensive understanding of the subject matter. The research methodology employed was research and development (R&D) utilizing the Instructional Development Institute (IDI) development model, which consists of define, develop, and evaluate stages. Primary data were gathered from experts in instrumentation, media, and materials, as well as feedback from lecturers and students. The findings revealed a high level of validity for the IoT trainer kit learning media. Media experts assigned a validity value of 0.93, while material experts provided a validity value of 0.86. The practicality of the media was confirmed by favorable responses from lecturers, indicating a practicality score of 87.31%. Additionally, students’ responses after the trial reflected a high practicality rating of 83.25%. Regarding effectiveness, the IoT trainer kit learning media demonstrated success in improving student learning outcomes, with a gain score of 77.25%, affirming its effectiveness. In conclusion, the IoT trainer kit Learning Media is considered valid, practical, and effective for teaching digital circuits within the Electrical Engineering Study Program at Muhammadiyah University of West Sumatra. Its utilization is expected to boost student engagement, creativity, and learning outcomes, potentially improving the overall quality of education.

“…Its capability to power up wirelessly electronics devices with low power consumption current. Research in this field recently gathered a lot of attention due to the potential of charging sensors wirelessly in problematic places and areas, investigating wireless power charging by using RF harvesting energy [5]. The essential theory behind this technique is to harvest the RF energy around the antenna or receiver to power sensors.…”

Wireless Power Collecting (WPC) present the future in powering and energizing intelligent Internet of Things (IoT) electronics devices. This chapter studies and utilizes a circuit to powering wirelessly IoT devices. The WPC offer a best technique to help researchers and engineers of modern societies to build cell blocks. The concept is to energy any IoT devices and sensors wirelessly from Radio Frequency (RF) power strength in the same areas that may be hard to achieve or potentially hazardous. We implemented the RF harvesting technology with IoT devices to increase the efficiency of sensors. The idea of this system is to power up and self-energize any IoT sensors wirelessly. This work studies two different topologies of a rectangular patch antenna and different RF harvesting circuit voltage multiplier configurations using a microwave power station as the input RF source. This work aims to utilize the wireless power transmission technique in the smart house solution. The proposed prototype gets all technical parameters to generate enough electricity to power up the bulbs 5 W wirelessly at a gap distance around a five meters. Finally, we test the RF rectifier circuit coupled with a twin patch antenna that can self-energize the bulb, eventually devices work without batteries.
