The impact of integrated electronics in medicine

There are two salient points which convey the essence of the impact of integrated electronics in medicine. First, the quality and availability of health care are becoming increasingly dependent on radically new diagnostic, monitoring, and prosthetic instruments provided by electronics. Second, many of these new instruments, such as ultrasonic imaging systems, blood flowmeters, and artificial inner ears, impose very stringent performance requirements, which can be met only through innovative application of integrated electronics. In summary, the initial impact of integrated electronics on health care is now visible, and consequently it is apparent that we are beginning a new era of revolutionary advances in medical instrumentation. Health care may indeed present the most promising opportunity to improve the quality of life in our society through electronics.     

Attosecond control and measurement: lightwave electronics

Electrons emit light, carry electric current, and bind atoms together to form molecules. Insight into and control of their atomic-scale motion are the key to understanding the functioning of biological systems, developing efficient sources of x-ray light, and speeding up electronics. Capturing and steering this electron motion require attosecond resolution and control, respectively (1 attosecond = 10(-18) seconds). A recent revolution in technology has afforded these capabilities: Controlled light waves can steer electrons inside and around atoms, marking the birth of lightwave electronics. Isolated attosecond pulses, well reproduced and fully characterized, demonstrate the power of the new technology. Controlled few-cycle light waves and synchronized attosecond pulses constitute its key tools. We review the current state of lightwave electronics and highlight some future directions.     

The chemistry of solid-state electronics

Since the original theoretical insights of Bardeen and Shockley about 40 years ago, the progress of solid-state electronics has been paced by the ability to control chemical bonding structures, particularly at surfaces and interfaces. The functioning of solid-state devices depends on being able to produce interfacial structures with a minimum number of defective chemical bonds. A series of chemical discoveries and insights, on germanium (Ge) and silicon (Si) surfaces and gallium arsenide-aluminum arsenide (GaAs-AlAs) interfaces, has brought the electronics revolution to its present state of development. In most cases, the technological consequences of these accidental discoveries could not be accurately foreseen. With that caution, the technological prognosis for some current research is also reviewed.     

Molecular electronics. It's all about contacts

A key requirement in molecular electronics studies is the ability to measure the conductivity of a single molecule. But as Hipps explains in his Perspective, such measurements are often more about contacts than about molecular conductivity. Depending on the experimental setup, DNA behaves like a semiconductor, insulator, or metal. Cui et al. have designed a method that overcomes some of these problems, opening the door to systematic, reliable, and reproducible studies of the molecule-contact interface.     

Scenes from a marriage--of optics and electronics

BALTIMORE-Exploring the common ground between optics and electronics, more than 6800 physicists, spectroscopists, and engineers gathered here from 21 to 26 May at the joint meetings of the Conference on Lasers and Electro-Optics and the Quantum Electronics and Laser Science conference. Participants unveiled new technologies that have sprung up on this common ground, such as an imaging technique that can gauge the chemical composition of materials. They also described ways to broaden that ground, such as a novel approach for integrating lasers and silicon chips-a challenge that has slowed progress toward a new generation of high-speed computers and communications.

Heterogeneous three-dimensional electronics by use of printed semiconductor nanomaterials

We developed a simple approach to combine broad classes of dissimilar materials into heterogeneously integrated electronic systems with two- or three-dimensional layouts. The process begins with the synthesis of different semiconductor nanomaterials, such as single-walled carbon nanotubes and single-crystal micro- and nanoscale wires and ribbons of gallium nitride, silicon, and gallium arsenide on separate substrates. Repeated application of an additive, transfer printing process that uses soft stamps with these substrates as donors, followed by device and interconnect formation, yields high-performance heterogeneously integrated electronics that incorporate any combination of semiconductor nanomaterials on rigid or flexible device substrates. This versatile methodology can produce a wide range of unusual electronic systems that would be impossible to achieve with other techniques.     

Plasmonics: merging photonics and electronics at nanoscale dimensions

Electronic circuits provide us with the ability to control the transport and storage of electrons. However, the performance of electronic circuits is now becoming rather limited when digital information needs to be sent from one point to another. Photonics offers an effective solution to this problem by implementing optical communication systems based on optical fibers and photonic circuits. Unfortunately, the micrometer-scale bulky components of photonics have limited the integration of these components into electronic chips, which are now measured in nanometers. Surface plasmon-based circuits, which merge electronics and photonics at the nanoscale, may offer a solution to this size-compatibility problem. Here we review the current status and future prospects of plasmonics in various applications including plasmonic chips, light generation, and nanolithography.     

A universal method to produce low-work function electrodes for organic electronics

Organic and printed electronics technologies require conductors with a work function that is sufficiently low to facilitate the transport of electrons in and out of various optoelectronic devices. We show that surface modifiers based on polymers containing simple aliphatic amine groups substantially reduce the work function of conductors including metals, transparent conductive metal oxides, conducting polymers, and graphene. The reduction arises from physisorption of the neutral polymer, which turns the modified conductors into efficient electron-selective electrodes in organic optoelectronic devices. These polymer surface modifiers are processed in air from solution, providing an appealing alternative to chemically reactive low-work function metals. Their use can pave the way to simplified manufacturing of low-cost and large-area organic electronic technologies.     

Computers and electronics in postharvest technology — a review

The article gives an overview of areas where computers and electronics have made a particular impact on the postharvest industry. These include environmental control and storage, quality monitoring, quality management, grading systems, inventory control, and management of product. Specific examples of the application of electronic systems have been given to illustrate the current state of postharvest technology, and some future predictions have been given. It is likely that consumer demand for improved quality, longer storage life, and guaranteed product safety will continue to grow. In a highly competitive market the industry will need to meet these demands, and electronic technology will play an increasingly important role. Improved sensors to assess quality are still needed, and handling and storage systems are likely to become increasingly sophisticated. In the latter half of the twentieth century technology has contributed much to improve the world's food supply, but it has also generated problems for the wider society, which will require attention in the next millennium.
