This chapter discusses the processes by which small drops of liquid are generated and delivered in inkjet printing, the rheological properties of the often complex fluids that are involved, the behavior of liquid drops during impact and spreading on a surface, and applications of inkjet printing to large‐area electronics. Many methods for drop generation have been devised, but the most important methods...
The most desirable patterning method for manufacturing organic field‐effect transistors (OFETs) should involve the direct patterning of active materials, in which the patterning and deposition are carried out in a single step, and should afford the ability to process large areas in a high‐throughput process. Inkjet printing is an attractive process for fabrication in many applications, such as organic...
The development of large‐area, flexible electronics applications, such as displays, sensors, and actuators that can cover arbitrary surfaces, would significantly expand the use of electronics in ways that are impossible with conventional circuits. One of the most effective approaches for developing such applications involves the use of printing technologies. However, a major obstacle to the development...
This chapter provides an overview of the device architectures that have been suggested in the past years to realize electrically reprogrammable nonvolatile memory arrays, specifically using organic semiconductors and mostly compatible with organic thin‐film transistors (TFTs). Ferroelectric memories have been extensively researched as an alternative nonvolatile memory to be integrated with Si technology...
In this chapter, the potential and limitations of the technologies currently available for flexible displays will be reviewed, including flexible substrates, the various display modes for flexible displays, and thin‐film transistors (TFT). In addition, the AMOLED panel, which is considered as “an ultimate display,” will be discussed, starting from its design to fabrication by using an organic thin‐film...
This chapter explores solar cells made of organic semiconductors as an alternative photovoltaic (PV) device that is favorable for large‐area, low‐cost production and that can provide additional benefits, such as flexibility, that are not easily available in conventional PV technologies. It briefly introduces the unique characteristics of organic photovoltaic (OPV) technologies along with their operational...
Flexible solar cells offer attractive opportunities towards fabrication cost‐reduction and the diversity of the photovoltaic product market. This chapter will mainly focus on the progress, with selected examples, on inorganic photovoltaics compatible with flexible substrates. Descriptions and discussions are grouped into three different sections depending on the methods required to deposit the active...
This chapter reports and discusses the main features and achievements of flexible bioinspired devices and biosensors for biomedical applications, while identifying the major perspectives and the factors that limit their widespread use. It describes two classes of Electrolyte‐Gated Organic Field Effect Transistors (EGOFETs) suitable for biosensing applications, in particular EGOFETs and organic electrochemical...
