“…The demand for wearable devices has grown tremendously in the last decade. The number of connected wearable electronic devices has increased by more than 100% in the last 4 years, rising from 325 million in 2016 to about 720 million in the year 2019 [114][115][116][117][118]. As technology continues growing at a high rate, these devices are expected to reach 1.1 billion by 2022 [116].…”

Next-generation communication systems and wearable technologies aim to achieve high data rates, low energy consumption, and massive connections because of the extensive increase in the number of Internet-of-Things (IoT) and wearable devices. These devices will be employed for many services such as cellular, environment monitoring, telemedicine, biomedical, and smart traffic, etc. Therefore, it is challenging for the current communication devices to accommodate such a high number of services. This article summarizes the motivation and potential of the 6G communication system and discusses its key features. Afterward, the current state-of-the-art of 5G antenna technology, which includes existing 5G antennas and arrays and 5G wearable antennas, are summarized. The article also described the useful methods and techniques of exiting antenna design works that could mitigate the challenges and concerns of the emerging 5G and 6G applications. The key features and requirements of the wearable antennas for next-generation technology are also presented at the end of the paper.

Robotics has advanced tremendously from performing simple pick-and-place tasks in structured environments to operating in a range of real-world environments and terrains full of uncertainties. Often these advances have been motivated by biological systems. [1] As a result, the field has grown from simple robotic arms performing preprogrammed industrial tasks [2] to human/ animal-like robots or prosthetic devices that autonomously conduct wide-ranging tasks using various sensory modalities. [3][4][5] The advances in robotics have closely followed the developments in the fields of functional materials, sensing, actuation, and communication technologies, as well as artificial intelligence, which altogether have enabled robots to mimic the morphology and functionalities of biological systems to a high degree. [6] As an example, the implementation of large-area tactile skin or electronic skin (e-skin) has allowed robots to exploit tactile feedback from the whole body for working in unstructured or cluttered environments, just as animals do. [5,7] Likewise, miniaturized and yet powerful actuators and electronic components have allowed the development of dexterous hands and agile robots. [8] In recent years, 3D/4D printing has also opened the ways for the development of sensitized robots with complex shapes and soft structures. [9,10] Thus, advances in robotics have closely followed the technological advances in other areas such as electronic hardware, advanced materials, and manufacturing. However, there is one critical area where robotics appears to have largely missed to follow the technological trend, i.e., the energy needed to power the robots.A reliable source of energy is critical for the smooth operation of autonomous robots, particularly in environments where mains power is not readily available. In fact, the majority of applications today require robots to be autonomous, and as such, they must rely wholly on batteries for their source of power. Analyzing the state of the art, we note that not much progress has been made in terms of adopting the advanced energy solutions in the robot, despite major advances in battery technology. [11] Starting from the first autonomous wheel-based robot Shakey [12] in 1966 to the state-of-the-art humanoid robots developed during the last 30 years and the quadrupedal MIT cheetah robot [13] of 2018, the battery the autonomous robots use has improved only in terms of light weight and energy density (Figure 1). [14][15][16] In contrast, the energy-storage technology itself has evolved from the bulky and leaky liquid electrolyte-based systems [17,18] to printed batteries, flexible supercapacitors (SCs) with safe electrolytes, and elegant textile-based devices. [19][20][21][22] The battery technology has improved in terms of a Watt-to-weight ratio, form factors, lifetime, ruggedness (thermal and chemical), etc., and nowadays, flexible, stretchable, and printed batteries are increasingly being explored.The energy requirement of robots can also be met with the harvesting of renewa...

“…One class of microbatteries is based on thin films; such energy sources have found application in wearable or implantable sensors and devices [8][9][10][11]. Li ion-based thin film microbatteries have been found in commercial wearable devices [12][13][14]. Especially for IoT devices not requiring recharging, Zn-air batteries are an interesting alternative, as they have even higher theoretical energy density than Li-ion batteries [15,16].…”

Portable and autonomous microdevices often require on-board power sources such as thin film microbatteries. Air microbatteries are an attractive power source for such devices due to their high specific energy density. One particularly appropriate air chemistry is based on Zn, due to the multiple microfabrication approaches compatible with Zn anode formation. We demonstrate fabrication approaches to realize Zn film anodes in different thickness regimes using microelectromechanical systems(MEMS) based fabrication techniques – evaporation, electrodeposition, and laser micromachining; and evaluate their relative performance as power sources in a primary battery configuration. These fabrication techniques enable films in thickness regimes ranging from the micron scale to hundreds of microns. The fabricated films have been characterized using scanning electron microscopy and energy dispersive X-ray spectroscopy, and were found to be dense and reasonably free from impurities. The electrochemical and discharge properties of the fabricated films were studied in an air battery configuration comprising a Zn anode-alkaline hydrogel electrolyte-metal catalyst stack, in which the anode had a surface area of 0.78 cm2. Evaporated Zn anodes (1-10 microns) yielded Zn utilizations of 96.5% and 82% at 10mA and 1mA discharge rates, respectively. The specific capacity of the evaporated Zn anodes was 791 mAh/g when discharged at 10 mA, close to the Zn theoretical specific capacity of 820 mAh/g. Electrodeposited Zn anodes (10-100 microns) yielded utilizations of 90.2% and 75.6% at 10 mA and 1 mA discharge rates, respectively. Laser micromachined Zn anodes (250 microns) yielded Zn utilization of 90% when discharged at 10 mA. These fabrication techniques offer the potential to realize high energy density Zn anodes of different thickness ranges for thin film microbatteries, which can be tailored to microdevice-based applications of interest.
