In a device platform that spans communications, human-machine interfaces and gaming, and medical diagnostics, ultrathin electronics can be worn as simply and unobtrusively as a temporary tattoo with the system developed by a research team led by Todd Coleman and John Rogers of the University of Illinois at Urbana-Champaign and Yonggang Huang of Northwestern University. Sensors and communication electronics are embedded into flexible transparent sheets that stick to skin. The unobtrusive quality of the device opens the potential for a host of measurements and control systems that could offer more accurate day-to-day data than laboratory figures (when patients are in unnatural conditions), while the use of other kinds of electronic modules permits covert communications and physiological-directed gaming.
In 1934, Bell Labs had invented magnetic recording tape. They then shelved it. Although not at the same time, they would go on to invent - and subsequently shelve or fail to bring to market or prevent from coming to market - digital subscriber lines, fax machines, fiber optics, and mobile phones.
