“…Although the standard coin cell used in these devices is bulky and noncompliant, fl exible and stretchable primary batteries have been developed as power sources for fl exible electronics. [ 111,[119][120][121] There is not currently a standard for user-replaceable fl exible primary batteries, however. Thus, if the lifetime of a fl exible medical device must outlast that of an appropriately sized primary battery, a rechargeable battery is preferable.…”

Advances in wireless technologies, low-power electronics, the internet of things, and in the domain of connected health are driving innovations in wearable medical devices at a tremendous pace. Wearable sensor systems composed of flexible and stretchable materials have the potential to better interface to the human skin, whereas silicon-based electronics are extremely efficient in sensor data processing and transmission. Therefore, flexible and stretchable sensors combined with low-power silicon-based electronics are a viable and efficient approach for medical monitoring. Flexible medical devices designed for monitoring human vital signs, such as body temperature, heart rate, respiration rate, blood pressure, pulse oxygenation, and blood glucose have applications in both fitness monitoring and medical diagnostics. As a review of the latest development in flexible and wearable human vitals sensors, the essential components required for vitals sensors are outlined and discussed here, including the reported sensor systems, sensing mechanisms, sensor fabrication, power, and data processing requirements.

“…Gaikwad et al proposed a technique to reinforce arbitrary battery electrodes by supporting them with mechanically tough, low-cost fi brous membranes. [ 210 ] An ingenious design was proposed by Aravindan et al by building a LiMn 2 O 4 | PVdF-HFP | TiO 2 cell comprising all one-dimensional electrospun nanofi bers, [ 211 ] whereas Leijonmarck established a paper-making process based on nanofi brillated cellulose to build single-paper fl exible Li-ion battery cells. [ 186 ] Regular cellulose based materials i.e., paper, cotton textiles, cellophane (also called "transparent nanopaper"), and rayon are intrinsically electrically insulating, justifying their application as battery separator.…”

all need to be used in conjugation with an energy storage system to provide smooth power leveling. Currently, electrochemical energy storage systems are by far the most optimal solutions for powering a broad range of technologies, expanding from compact and light-weighted portable electronic devices to stationary gridscale energy storage applications. [3][4][5][6] These energy storage devices (batteries and supercapacitors) store the available electrical energy in the form of chemical energy and release it whenever needed, by simply reversing the electrochemical reaction. [7][8][9][10][11] Among various available battery chemistries, lithium batteries and supercapacitors are the most promising technologies. [ 7,[9][10][11][12][13][14][15][16][17][18][19][20] Ever since the realization of the fi rst electrochemical energy storage cell by Alessandro Volta (end of 17th century), the working principle and its function has changed very little. [ 21,22 ] Basically, two redox couples (or charge storage electrodes), electrically and physically separated, are bridged by an ion conducting medium to constitute an electrochemical cell. This holds true also for modern Li-ion batteries, although the chemistry involved is much more complex. During operation, the electrons are transferred through an external circuit while ions shuttle through the electrolyte to counterbalance the depleted charge at the electrodes. [ 23 ] So far, much of the effort has been directed towards improvement of the energy and power characteristics by downsizing the active components, re-engineering the current collectors and separators, as well as fi ne-tuning the Batteries have become fundamental building blocks for the mobility of modern society. Continuous development of novel battery chemistries and electrode materials has nourished progress in building better batteries. Simultaneously, novel device form factors and designs with multi-functional components have been proposed, requiring batteries to not only integrate seamlessly to these devices, but to also be a multi-functional component for a multitude of applications. Thus, in the past decade, along with developments in the component materials, the focus has been shifting more and more towards novel fabrication processes, unconventional confi gurations, and additional functionalities. This work attempts to critically review the developments with respect to emerging electrochemical energy storage confi gurations, including, amongst others, paintable, transparent, fl exible, wire or cable shaped, ultra-thin and ultra-thick confi gurations, as well as hybrid energy storage-conversion, or graphene-incorporated batteries and supercapacitors. The performance requirements are elaborated together with the advantages, but also the limitations, with respect to established electrochemical energy storage technologies. Finally, challenges in developing novel materials with tailored properties that would allow such confi gurations, and in designing easier manufacturing techniques that can be widely adopted ar...

There is an increasing interest in thin and flexible energy storage devices to meet modern society's needs for applications such as radio frequency sensing, interactive packaging, and other consumer products. Printed batteries comply with these requirements and are an excellent alternative to conventional batteries for many applications. Flexible and microbatteries are also included in the area of printed batteries when fabricated using printing technologies. The main characteristics, advantages, disadvantages, developments, and printing techniques of printed batteries are presented and discussed in this Review. The state-of-the-art takes into account both the research and industrial levels. On the academic level, the research progress of printed batteries is divided into lithium-ion and Zn-manganese dioxide batteries and other battery types, with emphasis on the different materials for anode, cathode, and separator as well as in the battery design. With respect to the industrial state-of-the-art, materials, device formulations, and manufacturing techniques are presented. Finally, the prospects and challenges of printed batteries are discussed.
