By designing cognitive radio networks (CRNs) for low power wide area networks (LPWANs), adaptive spectrum sensing plays an important role in using frequency bands effectively. With spectrum sensing, existing spectrum holes are filled by enabling secondary users to use the licensed band that primary users do not use. Many researchers have proposed various optimization or artificial intelligence techniques in CRNs for spectrum sensing. However, there is hardly any adaptive spectrum sensing method integrated into the LoRa communication standard, which is a very popular LPWAN technology. For this purpose, an adaptive optimization based spectrum sensing methodology with an improved genetic algorithm is proposed in this study. Depending on this methodology, two fitness functions adapted to the LoRa-based network are defined. Thanks to these functions, the movement of individuals in the network population is provided. In parallel, received signal strength values of optimum LoRa nodes were determined by genetic coding, and bands to be used by SUs instead of PUs were discovered considering minimum bit errors. To verify the success of the proposed method, various simulation experiments were carried out. The performance results strikingly show that the proposed method is quite successful for LoRa-CRNs. For example, the proposed method significantly improved the bit error rate performance, and reduced the number of faulty transmissions caused by packet collisions. It also reduced the packet error rate by more than 8% per minute in a 200-node network.

The circuit helps the sensors realize signal readout, conversion, transmission, and complex logic functions. [19][20][21] The human-machine interface (HMI) system plays the role of the application layer in the field of the IoT. [22][23][24] By presenting the sensor information to users in a simple and user-friendly interface, the HMI system enables a good user experience. [25,26] In particular, in the context of the coronavirus disease 2019 (COVID-19) pandemic, the use of smart electronic technology to achieve real-time and wireless interactive sensing is necessary. [27][28][29] Smart contact lenses (SCLs) have been employed for monitoring information regarding the eyes, including physical information (e.g., pressure and temperature) and chemical information (e.g., glucose, protein, and pH). [30][31][32][33][34] These physiological signals are closely related to human health. For example, excessive intraocular pressure (IOP) can induce glaucoma, [35] the abnormal temperature of the ocular surface can cause dry eye syndrome, [36] and excessive glucose in tears may predict diabetic retinopathy. [37] Non-invasive monitoring of human health by using SCLs will aid in better understanding of the physiological state of the eyes and even the body; subsequently, effective measures can be employed in a timely manner for the early prevention or treatment of certain diseases. As personal health information can be monitored in real-time by using SCLs, patients no longer need to go to the hospital or rely on large medical equipment. [38][39][40][41][42] Therefore, the development of SCL devices in view of the rapid advances in IoT technology is an important research topic.In this review, we focus on the latest progress and prospects of integrated biosensors, circuits, and HMI systems on SCLs under the background of the rapid development of the IoT technology, as shown in Figure 1. First, we discuss the integration of biosensors on SCLs for physiological information monitoring of the eyes, including IOP monitoring, corneal sensing, color signals sensing, tear pH monitoring, and glucose sensing. Next, we focus on wireless communication circuits integrated into SCLs, which have different functions, such as physiological signal sensing circuits, sensing circuits for disease treatment, and circuits for power supply. Furthermore, we summarize SCLs used in the HMI system. WhetherThe rapid development of the Internet of Things (IoT) technology endows some traditional devices with intelligent functions. Compared with traditional contact lenses used for correcting vision or beautifying the eyes, smart contact lenses (SCLs) are developed to monitor some physiological information of the eye. Sculls can be used to continuously monitor eye diseases noninvasively in real-time. As a personal electronic device, SCs can aid people in understanding their physical condition better without affecting their personal life. This review mainly discusses the development direction and problems associated with sculls from the perspective of the IoT. SCs c...
