The world of semiconductors, displays, computers, printers, cell phones, personal digital assistants (PDAs), circuit boards, and many other electronic devices may soon experience a paradigm shift away from silicon chips, according to Glenn Sanders, VP of development at Rolltronics. The company has pioneered a new approach to electronics manufacturing by producing thin-film electronic devices on flexible substrates using roll-to-roll manufacturing techniques. "The first applications will probably involve flexible back planes for IT and PDA devices," says Sanders. Using roll-to-roll manufacturing, Rolltronics plans to work with private companies developing Internet devices, medical imaging equipment, electronic ID tags, electronic books and paper, and a variety of other "transformational" products. Other potential applications include logic, wireless, power, memory, and display components. The devices are constructed as a "sandwich" of five or six thin layers (such as the plastic used in overhead transparencies) laminated into a single unit. "We're still in the prototyping phase, but we expect to have test units in a year and small production quantities in 18 months," says Sanders.

Because of the increasing ubiquity of wearable technology, it would be easy to think that design of wearable devices is routine and involves common design and engineering knowledge. Missed efforts in development will be remembered once the devices are used in the field
This grab-bag of new fasteners and adhesives work with a range of materials they can attach to, as well as a wide variety of applications. Several are for use in consumer applications, such as wearables or other compact electronic assemblies, and some of the adhesives have extended service temperature ranges and cure at room temperature.
As governments, associations, and NGOs around the world seek to protect consumers, national and regional standards are becoming mandatory, challenging manufacturers and making testing and certification necessary for any product developed and brought to market.
