Flexible strain sensors have received extensive attention due to their broad application prospects. However, a majority of present flexible strain sensors may fail to maintain normal sensing performances upon external loads because of their low strength and thus their performances are affected drastically with increasing loads, which severely restricts large-area popularization and application. Scorpions with hypersensitive vibration slit sensilla are coincident with a similar predicament. Herein, it is revealed that scorpions intelligently use risky slits to detect subtle vibrations, and meanwhile, the distinct layered composites of the main body of this organ prevent catastrophic failure of the sensory structure. Furthermore, the extensive use of flexible sensors will generate a mass of electronic waste just as obsoleting silicon-based devices. Considering mechanical properties and environmental issues, a flexible strain sensor based on an elastomer (Ecoflex)-wrapped fabric with the woven structure was designed and fabricated. Note that introducing a “green” basalt fiber (BF) into a degradable elastomer can effectively avoid environmental issues and significantly enhance the mechanical properties of the sensor. As a result, it shows excellent sensitivity (gauge factor (GF) ∼138.10) and high durability (∼40,000 cycles). Moreover, the reduced graphene oxide (RGO)/BF/Ecoflex flexible strain sensor possesses superior mechanical properties (tensile strength ∼20 MPa) and good flexibility. More significantly, the sensor can maintain normal performances under large external tensions, impact loads, and even underwater environments, providing novel design principles for environmentally friendly flexible sensors under extremely harsh environments.

“…[32][33][34][35][36][37][38] Degradable batteries/capacitors are an area of current research interest for their potential economic, environmental, and health impacts. [27,39,[40][41][42] By comparison with the vast literature on traditional batteries, [12] there are relatively few examples of transient batteries in the literature due to challenges related to the fact that they must fulfill very different requirements than for traditional batteries (e.g., solid-state electrolytes such as polymer electrolytes, PEs, may not be conductive enough) [43][44][45] ; and this exciting area of science and engineering has attracted the attention of researchers from various disciplines investigating various feedstocks for components of degradable batteries (i.e., anodes, cathodes, electrolytes, and containers) including: peptides, [46] polysaccharides, [47][48][49] synthetic polymers (e.g., polycaprolactone, [50] poly(glycerol sebacate), [51] ionic liquids, [52,53] with examples of batteries that are metal containing [54][55][56][57][58] or indeed metal free.

Batteries are utilized in a multitude of devices encountered in our daily lives. Here we describe a comparative study of Magnesium‐air and Zinc‐air primary batteries using silk fibroin‐ionic liquid polymer electrolytes (composed of Bombyx mori silk fibroin and choline nitrate). The ionic conductivity of the films was of the order of mS cm−1 which is sufficient to satisfy the conductivity requirements for many battery applications, the open circuit voltages (V) for the Mg 1:1 SF:IL and 1:3 SF:IL batteries just after fabrication were ca. 1.8 and 1.7 V, respectively; the 1:1 SF:IL battery had a capacity of 0.84 mAh cm−2, whereas the 1:3 SF:IL battery had a capacity of 0.68 mAh cm−2. The open circuit voltages (V) for the Zn 1:1 SF:IL and 1:3 SF:IL batteries were in the range of 1.3 and 1.2 V just after fabrication; the 1:3 SF:IL battery displayed a capacity of 0.96 mAh cm−2 and the 1:3 SF:IL battery displayed a capacity of 0.72 mAh cm−2. Integration of the PE and substitution of the carbon cloth electrodes with degradable materials would offer routes to production of transient primary batteries helping to address the global issue of electronic waste (e‐waste).

Given the advantages of high energy density and easy deployment, biodegradable primary battery systems remain as a promising power source to achieve bioresorbable electronic medicine, eliminating secondary surgeries for device retrieval. However, currently available biobatteries are constrained by operational lifetime, biocompatibility, and biodegradability, limiting potential therapeutic outcomes as temporary implants. Herein, we propose a fully biodegradable primary zinc−molybdenum (Zn−Mo) battery with a prolonged functional lifetime of up to 19 days and desirable energy capacity and output voltage compared with reported primary Zn biobatteries. The Zn−Mo battery system is shown to have excellent biocompatibility and biodegradability and can significantly promote Schwann cell proliferation and the axonal growth of dorsal root ganglia. The biodegradable battery module with 4 Zn−Mo cells in series using gelatin electrolyte accomplishes electrochemical generation of signaling molecules (nitric oxide, NO) that can modulate the behavior of the cellular network, with efficacy comparable with that of conventional power sources. This work sheds light on materials strategies and fabrication schemes to develop highperformance biodegradable primary batteries to achieve a fully bioresorbable electronic platform for innovative medical treatments that could be beneficial for health care.
