Approved documents should be distributed in accordance with a defined distribution list. By minimizing the number of copies, the task of retrieving and updating distributed documents will become much easier. Some organizations print documents on colored paper so that a black and white photocopy can be easily recognized as a copy of the master. It may be necessary for...

Solution processable conductors come in three main elasses metals, metal oxides or organics. Printed metals, most notably as eleetrodes or RFID antennae, are mainly obtained by using partiele-based inks. Silver or gold partiele inks are eommercially available. Evonik has developed silver printing pastes, sueh as Silver 30 SN, a formulation of silver flakes in organie solvents, optimized for screen printing (Figure 2.6).

The final portion of the digital circuitry to be considered is the memory. This remains a complete unknown for organic/printed electronics at this time. The memory must necessarily be nonvolatile. For some RFID architectures, it will be necessary to provide EEPROMs or at least PROMs, since some programmability in the...

Organ printing refers to the placement of various cell types into a soft scaffold. This is fabricated by a computer-aided design template (12). The simultaneous printing of cells and biomaterials has been elucidated, which allows the precise placement of cells and proteins within three-dimensional hydrogel structures. Both the scaffold structure, and also the type of tissue that can be grown within the scaffold, can be controlled. 

Organ printing is in general a computer-aided, dispenser-based, three-dimensional tissue-engineering technology directed to the construction of functional organ modules and eventually entire organs, layer-by-layer.

Figure 8.11 shows steps involved in organ printing. The first step in organ printing is to fabricate spheroids in a scalable and reproducible manner. Also, these spheroids must be maximally standardized in their size in order to make them processable through a bioprinter nozzle or by other means without clogging...
