“…As can be seen from the Table 4., GOx/MWCNT−Pt−Au/CFE bioanode and apple tissue/CFE biocathode included BFC has acceptable OCP value. For power density value, according to the Table 4, developed BFC has smaller value compared with other four previous studies [15, 49–51] but better power density value than the one that included nanomaterials in both electrodes [52].…”

A biofuel cell (BFC) was fabricated by combining multiwalled carbon nanotube ‐platinum‐gold (MWCNT−Pt−Au) hybrid nanomaterial, glucose oxidase (GOx) and benzoquinone included carbon felt electrode (CFE) bioanode with apple tissue included CFE biocathode. The working parameters of bioanode were optimized both experimentally and chemometrically. For the biocathode, apple, banana and pear tissues were tried and best power output was obtained with apple tissue. By combining MWCNT−Pt−Au/GOx/CFE bioanode with apple tissue based biocathode, single cell, double cell with membrane and with salt‐bridge BFCs were formed. The best power output with highest current density were obtained with single cell BFC.

“…Performance of biocatalytic electrodes in biofuel cells can be improved by using micro/nano‐porous conducting supports, e. g., nanoporous gold electrodes [110,111] . Also, novel carbon‐based conducting materials, including buckypaper [112] (made of compressed carbon nanotubes) or graphene [113] . The biggest problem for practical application of fuel and particularly biofuel cells is their inability to satisfy the power/voltage parameters and operational stability required for specific needs.…”

This review aims at summarizing the history and state‐of‐the‐art in the areas of fuel and biofuel cells. The paper is addressed to a broad audience including experts and particularly to newcomers and students. Some parts of the review, particularly about fuel cells of different kinds, are rather general and mostly addressed to students, however, sections related to biofuel cells are more specialized and will be interesting for researchers working in this novel and challenging area. Many aspects discussed in the article represent personal opinions of the authors. The article is aimed at providing interesting and easy for reading material representing more concepts than specific experimental data. If the readers get excited about the topic, the authors’ goals will be satisfied.

“…The BFC retained 60% of the initial power density after 7 days. [244] Modifying the CNT anode using hierarchical Ni microstructures, rGO films, and Meldola's blue-tetrathiafulvalene (MDB-TTF) increased the surface area by 3000 times and enhanced the electron-transfer. MDB modification allowed uniform distribution of Pt nanoparticles on the cathode, increasing the surface area by 210 times and enhanced ORR compared to bulk Pt electrodes.…”

Soft robotics can interact with humans safely. 3) Devices built from stretchable materials have a greater mechanical degree of freedom. This allows electronics, displays, and sensors to be integrated into places that would be difficult or impossible with rigid devices and enables new types of human-computer interfaces. It also allows robotics to have enhanced levels of dexterity and complexity in movement (consider the octopus as an inspiring example). 4) Devices that can be deformed elastically can be engineered to have new or emerging properties, such as antennas that change frequency with elongation, [21] intelligent materials that can perform unconventional forms of logic, [22,23] or composites that change thermal conductivity, [24] electrical conductivity, [25] or dielectric properties with deformation. [26][27][28] Most robotic and electronic devices require electricity to function, as shown on the left side of Figure 1A. Electricity can power sensors, enable computation, drive locomotion, and transmit information. Although most devices use electricity from an outlet, such "tethered" devices create notable limitations. In addition to limiting the degree of freedom of robotic materials, plug-in devices must be within a chords-length of a functioning outlet, thereby confining the range of use of such devices. Although battery operated devices can operate for some time without being plugged-in, the need to do so periodically is at best a nuisance that limits the operating time of a device. At worst, it can lead to issues such as lack of compliance with wearable devices (that is, the device is taken off for charging and never put back on) or disruptions in operation (a particular problem for health care devices or remotely deployed devices). Thus, there is a compelling interest in harvesting energy from the ambient to create tetherless devices or even devices that need less charging. Figure 1A (right side) provides examples of applications that may benefit from harvesting, such as internetof-things (IOT) devices, soft robots, wearables, implantables, and deployables (that is, devices sent to remote locations that do not have electrical outlets). Energy Harvesting CategoriesStrategies to harness energy typically convert waste or otherwise unused energy from the ambient into electricity. Although This review highlights various modes of converting ambient sources of energy into electricity using soft and stretchable materials. These mechanical properties are useful for emerging classes of stretchable electronics, e-skins, bio-integrated wearables, and soft robotics. The ability to harness energy from the environment allows these types of devices to be tetherless, thereby leading to a greater range of motion (in the case of robotics), better compliance (in the case of wearables and e-skins), and increased application space (in the case of electronics). A variety of energy sources are available including mechanical (vibrations, human motion, wind/fluid motion), electromagnetic (radio frequency (RF), solar), and ther...
