A compound which is a good choice for an artificial electron relay is one which can reach the reduced FADH2 active site, undergo fast electron transfer, and then transport the electrons to the electrodes as rapidly as possible. Electron-transport rate studies have been done for an enzyme electrode for glucose (G) using interdigitated array electrodes (41). The following mechanism for redox reactions in osmium polymer—GOD biosensor films has... 

Interdigital micro mixers comprise feed channel arrays which lead to an alternating arrangement of feed streams generating multi-lamellae flows [39 2]. If processes have to be carried out with extended residence times (> 1 s) and/or at a temperature level different from the mixing step, tubes have to be attached to the interdigital micro mixers. Their internals comprise millimeter dimensions or below, if necessary. 

OS 89] [R 19] [P 69] Using a special reactor configuration with an interdigital micro-mixer array with pre-reactor, subsequent tubing and a quench, a yield of 95% at 0 °C was obtained [127]. The industrial semi-batch process had the same yield at -70 °C.

Figure 6. Generation/collection experiments for different fixed collector potentials in an interdigitated array of microelectrodes coated with poly(I) in CH3CN/O.I 14 [n-Bu4N]PF6. The potential of the collector electrodes is held at 0.0 V, -0.50 V, -0.59 V, -0.62 V, or -0.80 V vs. Ag+/Ag while the potential of the generator electrodes is swept between 0.0 V and -0.9 V vs. Ag+/Ag at 20 mV/s.

A central feature for the interdigitated configuration is that the arrays need to be periodic. A variation on this approach is to use interdigitated plates rather than rods (Figure 2b), which is analogous to stacking 2-D batteries with parallel connection. 

This paper discusses the prospects for creating 3-D architectures for batteries. We next introduce calculations for the 3-D interdigitated array battery (Figure 2a). which will illustrate the design considerations under which the 3-D configuration leads to better performance than the conventional 2-D one. Other sections then discuss the prior art in small power, followed by the materials, synthetic, and fabrication approaches required to achieve 3-D designs. Finally, we review the present status of the systems most likely to demonstrate true 3-D battery operation.
