The ORCID identification number(s) for the author(s) of this article can be found under https://doi.org/10.1002/adma.201805722.Self-powered electronics using triboelectric nanogenerators (TENGs) is drawing increasing efforts and rapid advancements in eco/biocompatible energy harvesting, intelligent sensing, and biomedical applications. Currently, the triboelectric performances are mainly determined by the pair materials' inherent electron affinity difference, and merely tuned by chemical or physical methods, which significantly limit the optional variety and output capability, especially for natural-biomaterial-based TENGs. Herein, a biocompatible triboelectric material with a programmable triboelectric property, multiple functionalization, large-scale-fabrication capability, and transcendent output performance is designed, by genetically engineering recombinant spider silk proteins (RSSP). Featuring totally "green" large-scale manufacturing, the water lithography technique is introduced to the RSSP-TENG with facilely adjustable surface morphology, chemically modifiable surface properties, and controllable protein conformation. By virtue of the high electrical power, a proof-of-principle drug-free RSSP-patch is built, showing outstanding antibacterial performances both in vitro and in vivo. This work provides a novel high-performance biomaterial-based TENG and extends its potential for multifunctional applications.

“…For example, flat surfaced Cu/PTFE TENG shown in the literature was shown to have a charge density of 40 μCm -2 only [33], much smaller than those of other reported TENGs. Several other positive triboelectric insulator materials have been employed to construct TENGs, such as silk [34], carbon nanotubes (CNTs) [35], glass [36] and polyamide-6 (PA6, Nylon) with varying degrees of success [37]. The silk/PET TENG obtained a maximum peak power density of only 10 mWm -2 , while the CNTs/PDMS TENG produced about 5 Wm -2 which was mainly attributed to the high surface area of CNT arrays [35].…”

Realizing the potential of polyethylene oxide as new positive tribo-material: Over 40 W/m2 high power flat surface triboelectric nanogenerators

The ongoing research into the negative tribo-materials has led to significant improvements in the performance of triboelectric nanogenerators (TENGs), however, very little attention has been paid for positive tribo-materials. This work reports on the use of poly(ethylene oxide) (PEO) as the positive tribo-material for the fabrication of TENGs and shows that PEO has much higher positive tribo-polarity than the existing choice of polyamide-6 (PA6). A 2 × 2 cm 2 TENG comprising of spin-coated flat PEO and polydimethylsiloxane (PDMS) films produces a voltage of up to 970 V, a current density of 85 mAm-2 , and a power of ~40 Wm-2 under a 50 N contact force. Comparatively, the PA6/PDMS TENG only produces 630 V, 30 mAm-2 , and a power of ~18 Wm-2 , showing the remarkable property of the PEO as the positive tribo-material. The results are further supported by the contact potential difference between PEO (1.26 V) and PA6 (0.87 V) obtained using Kelvin Probe Force microscopy. Furthermore the triboelectric behavior of PEO is explained in the context of the positively charged oxygen functional groups and the lower work function of PEO as compared to PA6. The work thus expands the current portfolio of materials used for triboelectric nanogenerators with great prospects.

human life. [1][2][3] To achieve such a dream, choosing natural biomaterials such as nucleic acids, [4][5][6] peptides, [7] proteins, [8,9] and polysaccharides [10] as the substitutes of fossil source-based synthetic chemicals is a promising way. Correspondingly, micro/ nanoscale fabrication on natural biomaterials receives great of importance, [11] and a spatially definable property with high precision to exactly position biomaterials on a surface is highly desirable [12][13][14][15][16][17][18] toward biodegradable and biocompatible green electronic, [19][20][21][22] optical, [23][24][25][26][27][28][29] sensor, [30] energy, [31] and environmental devices. [32] Typical examples down this road include silk fibroin, [12][13][14] polysaccharides, [10] and DNA origami-mediated lithography. [5] These approaches are part of great efforts to develop "green" lithographic processing in semiconductor industry that is eligible to lessen the exposure of workers and environment toward noxious chemical and reduce waste. [13] The adoption of these strategies allows the replacement of organic solvent with water to cast and develop a resist, accompanied with the exclusion of environmentally harmful components from material processing and fabrication. However, so far the lithographic processes based on existing natural biomaterials are difficult to be exploited in scale-up industrial application, because their limited quantities, high material, and processing cost as well as small deposition area impede the practical engineering of these biomaterials. [9] Moreover, the less-controlled variation on polymorph and polydispersity of biomaterials often influences the repeatability of results. [33] Recently, our group reported the use of phase-transited lysozyme nanofilm as the resist for photolithography and electron-beam lithography (EBL), with the cost being decreased and practical applicability being potentially demonstrated. [17] Continuous efforts along this way further require much cheaper material and simpler fabrication process for large-scale industrial uses. In this respect, we pay attention to egg white due to the following reasons. First, egg white is a very common natural biomaterial just taken from egg as our daily food, which makes it has great natural abundance with a low cost. Second, in contrast to other natural competitors usually requiring strict demands on the purity, polydispersity, and polymorph stability, egg white is a combination of multiple functional nutrients, [34] which could be directly utilized without further purification and Complex lithographic steps and the use of toxic chemicals in these processes are in conflict with a sustainable human society. Development of new inexpensive and green resist, simple alternative procedures, and nontoxic solvents is the key to move recyclable micro/nanofabrication from laboratory level to industrial application in large scale. Herein, precise control on protein fragmentation/aggregation upon photo/electron irradiation is conceived into egg white-based green resist...
