On the other hand, the external driving force can be greatly decreased, while the output power density (11.9 mW) and the durability of the equipment can be improved at the same time . They successfully demonstrated the TENG applications in night direction indication, insect capture, soil moisture detection, ambient temperature/humidity detection, and signal transmission. Recently, many excellent review articles have been published on the application of TENG in different and specific research fields. For instance, Liu et al. summarized the multi-domain applications of IoTs driven by advanced mechanical energy harvesters in the construction of smart city in recent years .
Wireless technologiescan include everything from short-range protocols such as Bluetooth, NFC, and RFID through to long-range ones like 5G and satellite systems. In between you’ll see formats like Wi-Fi, Zigbee, Z-Wave, and Thread. If you are concerned about cyber attacks, learnhow to save IoT devices from hackers.

Gu et al. proposed a particle transport-based TENG (PT-TENG) for self-powered mass flow detection and explosion warning. It is well known that pneumatic conveying of particles has been widely used in food industry , petrochemical industry, and other processing and electronic industries . PT-TENG can be used as a self-powered detector to monitor the mass flow of particles in a timely manner. Moreover, a self-powered explosion-proof alarm device can be further developed on this basis to effectively guarantee the safety of the factory.
The benefits of tracking and organizing things seem overwhelming to some people; even so, critics point out equally clear risks of monitoring people and things so much more closely. Do we want grocery stores to know even more about what we're heating than they do already? Do we want our homes packed with sensors, keeping tabs on us at all times?
The Best Smart Home Hubs We've Tested
The circuit diagram and design of the self-powered system are shown in Fig.4b. Depending on the outdoor windy environment, the capacitor can be quickly charged to reach the operating voltage of the monitoring system in a short time and subsequently implement the real-time monitoring process. In addition to monitoring the status of industrial facility and production, the prevention of laboratory accidents and special workshop accidents is also very important during the production process. Ma et al. designed a smart protective laboratory-coat based on a fabric TENG composed of PTFE yarns, which has four main functions for self-powered monitoring during the extreme working environments .
Relevant studies have shown that the external high electrostatic field can not only be used to accelerate seed germination and plant growth , but also improve the ion migration in the soil for better nutrient absorption . Li et al. reported a wind and rain energy-driven electric stimulation system based on all-weather TENG for improving crop yields . On the other hand, by harvesting the energy from environmental wind and raindrops, the all-weather TENG can be used to drive various agricultural sensors for optimizing the growth conditions of plants.
Applications of Internet of Things and Cloud Computing
When you set up your smart home effectively, then it is called home automation—you have automated many daily tasks. For example, setting the thermostat on echo mode automatically when you leave for work. Because devices are interconnected and capable of communicating with one another, they can often be set to perform certain functions in an automatic fashion. Communication and interconnectivity go hand-in-hand when it comes to IoT. As interconnectivity is about data sharing, communication takes things a step further by allowing devices to speak to and control one another.
People have been getting excited about this idea since it was originally suggested in 1999 by technology entrepreneurKevin Ashton, then working in brand marketing at Proctor & Gamble. Ashton realized his Internet of Things was a yellow-brick road to better efficiency and less waste for all kinds of businesses. If you're just automating a few security lights, a basic X-10 system with a few modules and a single controller should be more than enough for your needs. But if you want to run a more sophisticated setup, with many different appliances coming on and off in all kinds of different ways, you might want to use your home computer as the controller instead.
Google Assistant Hubs
In this section, various HMIs based on TENG assisted with ML methods, AR/VR applications, and digital twins are summarized to promote the construction of IoTs. The goal is to integrate the function of acquisition, processing, and execution of information together to construct the micro-system with multi-functionality and significantly improve the level of automation, intelligence, and reliability. As is known, various sensors are the most important elements in IoTs, which will generate a large amount of sensory data during their operation. Efficiently utilizing/analyzing the data assisted with AI can deliver timely analysis and feedback. Accordingly, the integration of AI and the IoTs can promote better and more rapid development of the era of IoTs .
Similarly, Yeh et al. proposed a self-powered smart window system with an electrochromic reaction driven by TENG operating under wind or raindrops . In addition, Tan et al. presented a rotary FS mode TENG for driving the anti-fog device . Through the triboelectricity signal generated by TENG, droplets oscillate on the glass surface and condense due to the difference of triboelectric potential distribution.
However, the interconnectivity of devices is the fundamental basis of the terminology. Perspectives on the challenges and future research directions of TENGs in IoTs have been proposed. At Cognizant, we help our clients do what others can’t—operate with human insight, but at superhuman speed. A lot of progress has been made in those areas, but another recurring challenge is platform fragmentation. In the smart home space, Alexa and Google Assistant accessories often won’t work with HomeKit, or vice versa. The Matter standard will hopefully address this, but it’s still very new.
In order to better diagnose the fault of rolling bearings, Han et al. glued flexible interdigital electrodes to the outer ring of rolling bearings to form a rolling TENG , as shown in Fig.6c. The variation of output current amplitude and frequency with rotation speed is analyzed. Based on the model of output signals, a variety of classification algorithms are used for ML, and the fault characteristic frequency of the TENG output current is obtained when the outer ring, inner ring, and ball part failed. The achieved accuracy is more than 92%, which proves that TENG has a good application prospect in rolling-bearing fault diagnosis. Wireless sensor network is the core of IoTs, which is commonly composed of more than one billion sensors and electronic devices .
It shouldn’t be amazing when you think about the comfort and facilities that brilliant home gadgets offer. Since these IoT gadgets are interconnected, it becomes more straightforward to deal with numerous activities. This category is less popular even though it gains increasing interest and often shines at CES. In this category, you will find smart beds with sleep tracking sensors and in-built Alexa, mirrors with skin analytics and physical assessment capabilities and the whole smart bathrooms with intelligent toilets such as Numi 2.0.
These systems can range from lighting and temperature control to security cameras and surveillance. In some cases, they can even include locking and unlocking your doors. The term “Internet of Things” refers to the ever-growing network of physical objects that contain embedded technology to communicate and sense or interact with their internal states or the external environment. IoT devices are now so commonplace that there are over six billion connected things in use worldwide today. “Smart” technologies are devices that can be controlled remotely by a phone, tablet, or computer. While an IoT home is connected to the internet, some devices in a smart home may not be online.
Working with the IoT
If things communicate using IP, or use something like WiFito talk to an Internet-connected router, it opens up the possibility of controlling them from a Web browser anywhere in the world. That's why we're now seeing home security and monitoring systems that allow you to do things like turning your central heating on and off with smartphone apps. In summary, we can conclude that home automation seeks to improve the day-to-day life of people in their homes, with smart appliances, automate tasks or be able to control devices. IoT devices are used especially for sending information and connecting devices, but not necessarily at home, but also in industries and many other places. IoT can also be said as the digital interconnection of objects that we use in our day to day.
