“…[63] Modifying bioelectrodes with metal NPs and/or NWs has been suggested to improve the electron transfer performance from the biocatalyst to the electrode in microbial BFCs [64] and enzymatic BFCs. [65] An early work by Nishioka and co-workers [66] reported a w-BFC using silver NWs (AgNWs) decorated polydimethylsiloxane (PDMS) electrodes (Figure 3a). Biocatalysts glucose oxidase (GOx) coupled with mediator ferrocene, and bilirubin oxidase (BOD) were drop-cast onto the electrodes to form bioanode and biocathode, respectively.…”

The booming field of wearable devices has nourished progress in developing multifunctional wearable energy sources that can withstand deformations while maintaining their electrochemical functions. Unlike energy storage systems such as rechargeable batteries and supercapacitors, wearable biofuel cells (w-BFCs) generate green electricity from energy-dense carbon-neutral fuels via highly efficient bioelectrochemical reactions, delivering excellent biocompatibility, remarkable environmental sustainability, and exceptional capability of miniaturization. These desirable merits give w-BFCs great potential in the field of wearable applications. Moreover, emerging studies of w-BFCs in self-powered biosensing, controlled drug delivery, and wound dressings have greatly expanded their possible fields of application. Recent progress and strategies to accomplish flexible and stretchable w-BFCs are summarized here. Novel materials and configurations with tailored features that can be employed to fabricate w-BFCs are elaborated and discussed. Current applications and near-future applications of w-BFCs in health-monitoring and medical treatment fields are outlined. Furthermore, challenges and perspectives regarding this emerging field of materials science and engineering are also emphasized.

“…The substrates for many stretchable electrodes are mainly textiles and elastomeric polymers with intrinsic stretchability. A variety of stretchable polymers, such as polydimethylsiloxane (PDMS), [43] polyurethane, [13] Ecoflex (silicone rubber), [13] and styrene-(ethylene-butylene)-styrene (SEBS), [44] can serve as the underlying platforms for stretchable bioelectronics. For example, an elastomeric thin film, based on Ecoflex and PU, was introduced as a stretchable underlying base material for fabricating temporary-tattoo BFCs (Figure 2A).…”

The growing power demands of wearable electronic devices have stimulated the development of on-body energy harvesting strategies. This article reviews the recent progress on rapidly emerging wearable biofuel cells (BFCs), along with related challenges and prospects. Advanced on-body BFCs in various wearable platforms, e.g., textiles, patches, temporary tattoo, or contact lenses, have enabled attractive advantages for bioenergy harnessing and self-powered biosensing. These noninvasive BFCs open up unique opportunities for utilizing bioenergy or monitoring biomarkers present in biofluids, e.g., sweat, saliva, interstitial fluid, and tears, toward new biomedical, fitness or defense applications. However, the realization of effective wearable BFC requires high-quality enzymeelectronic interface with efficient enzymatic and electrochemical processes and mechanical flexibility. Understanding the kinetics and mechanisms involved in the electron transfer process, as well as enzyme immobilization techniques, is essential for efficient and stable bioenergy harvesting under diverse mechanical strains and changing operational conditions expected in different biofluids and in a variety of outdoor activities. These key challenges of wearable BFCs are discussed along with potential solutions and future prospects. Understanding these obstacles and opportunities is crucial for transforming traditional bench-top BFCs to effective and successful wearable BFCs.

Harnessing electrochemical energy in an engineered electrical circuit from biochemical substrates in the human body using biofuel cells is gaining increasing research attention in the current decade due to the wide range of biomedical possibilities it creates for electronic devices. In this report, we describe and characterize the construction of just such an enzymatic biofuel cell (EBFC). It is simple, mediator-free, and glucose-powered, employing only biocompatible materials. A novel feature is the two-dimensional mesoporous thermally reduced graphene oxide (rGO) host electrode. An additionally novelty is that we explored the potential of using biocompatible, low-cost filter paper (FP) instead of carbon paper, a conductive polymer, or gold as support for the host electrode. Using glucose (C 6 H 12 O 6 ) and molecular oxygen (O 2 ) as the power-generating fuel, the cell consists of a pair of bioelectrodes incorporating immobilized enzymes, the bioanode modified by rGO−glucose oxidase (GOx/rGO), and the biocathode modified by rGO−laccase (Lac/rGO). Scanning electron microscopy/energy-dispersive X-ray spectroscopy (SEM/ EDX), transmission electron microscopy, and Raman spectroscopy techniques have been employed to investigate the surface morphology, defects, and chemical structure of rGO, GOx/rGO, and Lac/rGO. N 2 sorption, SEM/EDX, and powder X-ray diffraction revealed a high Brunauer−Emmett−Teller surface area (179 m 2 g −1 ) mesoporous rGO structure with the high C/O ratio of 80:1 as well. Results from the Fourier transform infrared spectroscopy, UV−visible spectroscopy, and electrochemical impedance spectroscopy studies indicated that GOx remained in its native biochemical functional form upon being embedded onto the rGO matrix. Cyclic voltammetry studies showed that the presence of mesoporous rGO greatly enhanced the direct electrochemistry and electrocatalytic properties of the GOx/rGO and Lac/rGO nanocomposites. The electron transfer rate constant between GOx and rGO was estimated to be 2.14 s −1 . The fabricated EBFC (GOx/rGO/FP-Lac/rGO/FP) using a single GOx/rGO/FP bioanode and a single Lac/rGO/FP biocathode provides a maximum power density (P max ) of 4.0 nW cm −2 with an open-circuit voltage (V OC ) of 0.04 V and remains stable for more than 15 days with a power output of ∼9.0 nW cm −2 at a pH of 7.4 under ambient conditions.
