“…Previous studies of conducting fabric have been done using PEDOT [14] and aniline [15] polymerized on nylon 6 fabric; they yielded maximum conductivities of 2 S/cm and 0.06 S/cm respectively. Fabric coated with polypyrrole by Electrochemical Polymerization yielded conductivity up to 10 S/cm [16].…”

“…The resulting increase in the effective contact area between PEDOT-S and the IL:PIL electrolyte mixture would permit considerably faster dedoping polyaramide as well as silk fi bers with conducting polymers from solution [ 6 , 11 , 28 , 29 ] or by means of in situ polymerization. [30][31][32] Electrochemical transistors (ECTs) were fabricated by arranging PEDOT-S stained fi bers, which consisted of a number of monofi laments (Figure 1 b), in a simple cross-junction confi guration. The gap between the two fi bers was bridged with a drop of a 1:1 electrolyte mixture by weight of the ionic liquid (IL) 1-butyl-3-methylimidazolium bis(trifl uoromethanesulfonim ide) ([bmim][Tf 2 N]) and the corresponding polymer ionic liquid (PIL) poly(1-vinyl-3-methylimidazolium) bis(trifl uoromethane sulfonimide) (poly[ViEtIm][Tf 2 N]) (Figure 1 a).…”

Fiber-based opto-electronic components such as light-emitting diodes (LEDs), [ 1 , 2 ] solar cells, [3][4][5] electrochromic pixels [ 6 ] and transistors [7][8][9][10][11][12] attract increasing attention for their alternative, nonplanar device architectures, which readily permit integration into 'smart' fabrics. Furthermore, devices such as transistors facilitate advanced patterning schemes of electronic circuitry through judicious weaving. [9][10][11][12] In particular conjugated polymers are suited as the (semi)conductor since they either inherently possess the required mechanical toughness or can be processed together with suitable structural polymers-including both, natural and synthetic macromolecules [ 13 , 14 ] -and thus permit the manufacture of fl exible artifacts such as tapes and fi bers. Without doubt, one of the most alluring textile materials is silk from the silkworm Bombyx mori with its delicate texture and brilliant luster. Besides, once thoroughly degummed Bombyx mori silk offers a high degree of biocompatibility, [ 15 ] which is an indispensable characteristic in particular for electronic devices that are intended to operate in a biological environment. As a result, the design of optical, [ 16 , 17 ] electrical [ 18 , 19 ] and electronic [ 20 ] components on silk-based templates has been the subject of much recent research. However, all examples have -so far-been limited to devices that comprised inorganic metal/semiconductor thin-fi lm structures on 'silk fi lms' that were produced from dissolved silk proteins. Clearly, although attractive due to their biodegradability (cf. Ref. 19 and 20) such architectures fail to benefi t from the extraordinary mechanical properties of pristine silk fi bers [ 21 , 22 ] and cannot be woven into fabrics. In a previous report, we have demonstrated that conjugated polyelectrolytescompounds that are uniquely suited to functionalize polypeptide structures [23][24][25][26] -permit facile staining of recombinant spider silk as well as natural Bombyx mori silk. [ 13 ] Depending on the choice of conjugated polyelectrolyte this approach enabled us to produce electrically conductive or photoluminescent fi bers. Here, we explore by which means such conducting silk fi bers can be incorporated as the structural as well as active component into electrochemical transistors (ECTs) that employ an electrolyte mixture composed of imidazolium-based ionic liquids as the electrochemical medium. ECTs offer unique possibilities for the realization of fi ber-based electronic circuits because of their relative insensitivity to the precise device geometry. [ 11 ] Ultimately, we anticipate that such components will permit fully integrated woven logic based on silk fi bers.We elected to work with silk fi bers from the silkworm Bombyx mori because of their availability and widespread use in textile manufacturing. Discrete degummed silk fi bers and threads thereof were obtained from Aurora Silk (Portland, Oregon, USA) and were used as received. As the conjugated polyelectrolyte we c...

This paper reports on a miniaturized microbial fuel cell with a microfluidic flow-through configuration: a porous anolyte chamber is formed by filling a microfluidic chamber with three-dimensional graphene foam as anode, allowing nutritional medium to flow through the chamber to intimately interact with the colonized microbes on the scaffolds of the anode. No nutritional media flow over the anode. This allows sustaining high levels of nutrient utilization, minimizing consumption of nutritional substrates, and reducing response time of electricity generation owing to fast mass transport through pressure-driven flow and rapid diffusion of nutrients within the anode. The device provides a volume power density of 745 μW/cm3 and a surface power density of 89.4 μW/cm2 using Shewanella oneidensis as a model biocatalyst without any optimization of bacterial culture. The medium consumption and the response time of the flow-through device are reduced by 16.4 times and 4.2 times, respectively, compared to the non-flow-through counterpart with its freeway space volume six times the volume of graphene foam anode. The graphene foam enabled microfluidic flow-through approach will allow efficient microbial conversion of carbon-containing bioconvertible substrates to electricity with smaller space, less medium consumption, and shorter start-up time.
